Error cards and Misprints, are cards in the TCG that have certain elements on the card that are incorrect. They include design errors, misprinted ink errors, and all known repeating factory errors. Design errors that were corrected are much rarer variants making them more desirable. Uncorrected design error cards were mass produced so they are not valuable to collectors. Errors cards that are listed on the Official TCG Errata will be denoted by (Erratum)

Original Series

Base Set

 
Vulpix listed with "HP 50" instead of "50 HP".

Corrected Errors:

  • Alakazam: Subtle blue ink streaks on the holo background of some unlimited prints.
  • Blastoise: "Stage Error Blastoise". The word "stage" is missing at the top right corner on unlimited prints.
  • Blastoise: "Illustrator Error Blastoise". The word "Illus." is missing at the bottom left corner before Ken Sugimori's name found on unlimited prints. Much rarer than the "Stage Error".
  • Blastoise: "Red Dot Blastoise". A small red ink dot above Hydro Pump's water energy symbol appears on unlimited prints. High population.
  • Chansey: "Black Dot Chansey". A black ink blob can be seen above the "x" of "next" in Chansey's Scrunch attack on unlimited prints.
  • Charizard: "Black Dot Charizard" A small black ink dot can be found on the "t" of "Nintendo" at the bottom of unlimited prints. Notably this error has a slight holobleed and holofoil shift at the bottom of the holo. High population.
  • Clefairy: "Red Heart Clefairy". A magenta ink hickey coincidentally resembling a heart inside of a circle can be seen above the artwork on unlimited prints. Very rare error with the copies having a full circle being most desirable.
  • Clefairy: "Black Dot Clefairy". A big black ink blob can be seen covering the "N" and the "O" of "now" in Clefairy's Sing attack on unlimited prints.
  • Gyarados: Low black ink gray text error from the theme deck print run. Another error is a reddish black dot can be found on the bottom yellow border of some unlimited prints, directly under the "96."
  • Hitmonchan: Low black ink gray text error from an unlimited theme deck print run. Unlimited Hitmonchan can also be found with a large holobleed at the top right of the card over the HP and energy symbol.
  • Machamp: "Screen Holo". Unlimited Machamps can rarely be found with a "screen" of yellow vertical lines across all or part of the card. pop<20
  • Machamp: "Green Dot Machamp" A blue ink blob over the "H" in "HP" can be found at the top right on unlimited prints. pop<50
  • Machamp: Some unlimited print Machamps were printed with a darker gold border. pop<5
  • Mewtwo: Low black ink gray text error from an unlimited theme deck print run. Another error that can be found on unlimited prints is subtle blue ink streaks on the background of the holo.
  • Ninetales: "No Damage Ninetales". Design error where the number "80" is missing on the Fire Blast attack on some rare shadowless prints. This error has only been found in some shadowless Brushfire theme decks.
  • Ninetales: A black ink hickey obstructing the "es" in Ninetales' name on some unlimited prints. Also unlimited Ninetales can be found with a red hair or string obstruction hickey at the bottom right of the card. Unlimited Ninetales can also be found as a low black ink gray text error from a theme deck print run.
  • Venusaur: Blue ovals scattered randomly across the card. Each copy is different ranging from small to large ovals caused by water obstructions on the yellow plate.
  • Beedrill: "D.efending Error Beedrill". Design error where some unlimited Beedrill cards were accidentally printed with a period in the middle of the word "D.efending" in the Poison Sting attack.
  • Dragonair: "Rainbow Smear Dragonair". A rainbow-like smudge covering the letter "u" in the word "number" on 1st edition and shadowless prints.
  • Dragonair: Unlimited print is known to have pink and gold ink circles in the artwork.
  • Electrode: Blue and pink ink hickey on it's right cheek on some unlimited prints.
  • Charmeleon: "Red Heart Tattoo Charmeleon". Unlimited print red ink hickey at it’s left hip. The shape inside the yellow ring resembles a heart. pop<20
  • Charmeleon: "Blue Slash Charmeleon". Rare unlimited Charmeleon looking like it slashed 2 blue lines across the artwork just below it's actual slash. Seems to be caused by 2 hair obstructions getting on the blue layer. pop<5
  • Dratini: Pink and Blue Lasso Dratini. Looking like a pink lasso around Dratini's head from a long wavy hair obstructing the blue plate's ink on one variant. On a different variant the lasso is blue from printed addition blue ink from being on the blanket cylinder. pop<5
  • Haunter: A few shadowless prints were found with a black ink hickey resembling a ghost face in the artwork. It's just above Haunter's left ear.
  • Poliwhirl: A few unlimited Poliwhirl cards were printed with a blue ink hickey at the top right at the word "Pokemon" above the water energy symbol.
  • Wartortle: "Evolution Box Wartortle". Design error where a picture of Wartortle was accidentally printed in the evolution box instead of Squirtle on unlimited print. Notably all Portuguese 1st edition and unlimited Wartortles have this error.
  • Wartortle: Blue ink hickey at the top right of some unlimited prints. Same size as the water energy symbol just to the right of it. pop<5
  • Abra: "Jet Plane Abra". A small black ink spot resembling a jet plane can be found in the sky left of Abra on some unlimited prints. pop<10
  • Abra: Yellow stain at the top left of the card in varying degrees on some unlimited prints.
  • Bulbasaur: "Sunbeam Bulbasaur". Rare shadowless ink error resembling two yellow sunbeams coming down over Bulbasaur's body. The yellow lines appear to be missing blue ink. All copies weirdly also have a large column of missing gloss from the top of the yellow lines down to below Bulbasaur's body. pop<10
  • Charmander: "Scratch Error Charmander". A few unlimited prints have been found with a red smear over the “h” in it’s “Scratch” attack causing half of the "h" to be missing. pop<5
  • Charmander: Repeating red ink hickey over the "h" in Scratch on unlimited. Makes a yellow ring of missing magenta ink. Same error can be found at bottom left over the "Mit" in Mitsuhiro and at the top right above the "50" in 50 HP of unlimited. All 3 have pops<5.
  • Diglett: "Rotated Energy Symbol Error Diglett". The fighting energy symbol can be found rotated 90 degrees left on the Dig attack of some unlimited prints found from certain 2-Player Starter Sets.
  • Machop: A few unlimited Machop cards were printed with three greenish-yellow dots on Machop's belly.
  • Magnemite: Blue and red ink hickey on it's forehead on a couple of unlimited prints.
  • Pikachu: "Ghost Stamp Pikachu". Rare shadowless copies can be found with an incomplete 1st edition stamp. Reading only the outline of "E ITION", it's completely missing the "1" and the "D." Only has been found in shadowless "Zap!" theme decks on yellow cheeks Pikachu's.
  • Ponyta: A few unlimited cards were found with a light blue ink ring hickey above it's tail in the sky. Caused by an obstruction on the magenta blanket looking a call for batman.
  • Rattata: Two red ink dots can be found on shadowless copies at the middle right side of the card.
  • Squirtle: "Red Diamond Squirtle". Shadowless copies can be found with a little red ink diamond over the "ve" in "prevent" of it's Withdraw attack. pop<75.
  • Squirtle: Some unlimited copies have been found missing the bottom half of "tle" in it's name from a black in obstruction. pop<10
  • Staryu: A red ink hickey at the top left of the artbox making a yellow ring on some unlimited cards. pop<5
  • Tangela: A huge blue ink hickey on the right of it's face on some unlimited prints. This is likely the largest ink hickey in the set. pop<15
  • Vulpix: "Blue Butt Vulpix". A blue ink obstruction can be found on Vulpix's butt on both 1st edition and shadowless prints. The 1st edition version is rarer.
  • Water Energy: Mass produced design error where the top banner is misaligned higher than it's supposed to be. The top, left, and right banner perimeter is also missing the design.
  • Grey Stamps: All 102 cards from the 1st edition print run can be found as a grey or faded 1st edition stamp. Holofoil grey stamps are much harder to find compared to the common/uncommon cards. Note: As every Machamp was printed with a 1st edition stamp, it is the most common holo to suffer from this error.
  • Back Stamps: Some 1st edition commons and uncommons have partial inverted 1st edition stamps on the card backs from ink transfer. It's believed that the black ink was too heavy and didn't fully dry by the time the sheets were printed and stacked. Some card backs received addition black ink and some card backs had their ink removed to be white back stamps.
  • White Stamps: Some 1st edition commons and uncommons can be found with a partially white stamp due to missing ink from ink transfer to the sheet stacked on top of it. Can also be on the back.
  • Dark Gold Borders: Some Shadowless nonholo rares, uncommons, and commons have been found printed with extremely dark gold borders as well as some unlimited Machamps. One recent occurrence was the com/uncom 2-player starter set deck. A few 1st edition commons have also been found.
  • Holo Shifts: The unlimited holos besides Machamp, can be found with an extreme holoshift. Extremely rare only about two examples of each have been found.
  • UK Print Yellow Shifts: Commons from 2000 UK print can be found with a severe yellow ink shift to the right and downward. Extremely rare, only about 10 have been found and none of them were starters.
  • Inverted Backs: All the unlimited holos, uncommons, and commons have been found having an upside-down back plus majorly off-center. The error is actually an inverted front because the backs are standardly printed first. It's fun to display these errors in a binder with the front upside-down.
  • Yellow Stain Shadowless Holos: Most of the shadowless holos have been found with vertical yellow ink lines across the card. Some have a lot of lines while some only have one.
  • Yellow Saturated Holos: Most of the unlimited holos have been found with extreme oversaturated yellow ink across the whole card.
  • Crimps: Crimps can be found on any card with the most common card being unlimited Machamp. Vertical crimps are the rarest with only about three known occurrences of unlimited uncommons and would have likely been hanging halfway out of the back of an unsealed pack. Long stem hanger pack crimps are also extremely rare with only about 10-15 known examples mostly all unlimited uncommons with a few being commons partially crimped. Fully crimped cards having a cut line or fully cut through are also extremely rare and are among the most desirable crimp types. Besides Machamp, the rare cards are extremely unlikely to be crimped due to being in the middle of the pack. There are also a few examples of square corner cards being crimped apparently due to the sharp corners affecting it's placement into the booster pack.

Uncorrected Errors:

  • Gyarados: All Base Set Gyarados were printed with the "6/102" too far to the left.
  • Machamp: The shadowless version has the fighting symbols in all four of the fighting energy symbols noticeably shifted to the right.
  • Kakuna: In the 1st Edition and shadowless versions of this card the bio incorrectly reads "Cocoon Pokémon. Length: 2' 0", Length: 22 lbs" instead of "Weight: 22 lbs".
  • Bulbasaur: In the 1st Edition and shadowless versions of this card the bio incorrectly reads "Seed Pokémon. Length: 2' 4", Length: 15 lbs" instead of "Weight: 15 lbs".
  • Caterpie: The 1st Edition and Shadowless versions of this card have their HP listed as "HP 40" instead of "40 HP".
  • Metapod: The 1st Edition and shadowless versions of Metapod cards have their HP listed as "HP 70" instead of "70 HP".
  • Nidoran♂: Nidoran♂ is misspelled as "Nidoran ♂".
  • Sandshrew: The 1st Edition and Shadowless versions of this card have Sandshrew's Sand-attack read "If the defending Pokémon tries to attack during your opponent's next turn, your opponent flips a coin. If tails this attack does nothing" while it's supposed to say "that attack does nothing".
  • Voltorb: In the 1st Edition and Shadowless versions of this card the Bio at the bottom of the card reads "Usually found in power plants. Easily mistaken for a Monster Ball, it has zapped many people." The unlimited version was corrected and monster ball is replaced with "Poké Ball." The error refers to Poké Balls as their Japanese counterparts Monster Balls.
  • Vulpix: The 1st Edition, Shadowless, and unlimited prints have their HP printed as "HP 50" instead of "50 HP". This was only corrected in the UK released 1999-2000 4th print run.
  • Imposter Professor Oak: The 1st Edition and Shadowless versions of this card read "Impostor Oak" instead of "Imposter Oak".
  • Bill (1st and Normal Edition): All prints of this card have a transparency error; there should not be a white space around Bill's arm.
  • Switch: The 1st Edition and Shadowless versions of this card read "Switch 1 of your own Benched Pokémon with your Active Pokémon." where the word "own" is completely unnecessary and was corrected in the unlimited versions of this card.
  • Japanese Base Set Holofoil cards: All holofoil cards with an evolution box have the holographic overlapping the bottom on the evolution box.

Variants incorrectly regarded as errors:

  • Machamp: "Cosmos Holo Machamp". Base Set was printed using the starlight holofoil pattern. However, some Machamps were printed with the Cosmos holofoil pattern instead. These Machamps were found inside the 2-Player CD-ROM Starter Set deck. This deck contained Base Set 2 cards and a reprint of the unlimited Machamp with Base Set 2's cosmos pattern.
  • Ninetales: "Black Flame Ninetales". A rarer variant only for unlimited print where the flames of the artwork are black like the shadowless artwork instead of blue like most of the unlimited prints. Apparently Wotc changed the design at some point early during unlimited print making the black flame Ninetales more desirable.
  • Pikachu: "Red Cheeks Pikachu". A desirable variant found on 1st edition, shadowless, and the E3 promo prints are often regarded as errors. The illustrator of the card, Mitsuhiro Arita, originally submitted the artwork of the Base Set Pikachu as having yellow cheeks. Wizards of the Coast employees thought the cheeks were supposed to be red so they changed the artwork to red without Mitsuhiro Arita's permission. Eventually they switched it back to having yellow cheeks as Mitsuhiro had originally intended. Pikachu's cheeks turn yellow during an attack which explains why Mitsuhiro Arita wanted them yellow. Because this was an intentional design change it should not be considered an error.

Jungle

Corrected Errors:

  • Clefable: The prerelease promo holo can be found with both a misaligned and inverted prerelease stamp.
  • Flareon: Unlimited holo Flareon can be found with multiple magenta ink hickies with white rings in the background of the artwork. They are pretty subtle.
  • Pinsir: A number of 1st edition Pinsir cards have holo-like scratch that can be seen going above and through the 1st edition stamp.
  • Clefable: A handful of unlimited non-holo Clefable cards were printed with a red ink mark on Clefable's body.
  • Kangaskhan: "Green Spear Kangaskhan". A number of unlimited cards were printed with a streak of missing magenta ink resembling a greenish spear is Kangaskhan's hand. There's also a subtle red streak above it from missing cyan ink.
  • Snorlax: "Yellow Highlighter Snorlax". A number of unlimited Snorlax cards were printed with a large streak of missing magenta ink making it look like a yellow highlighter was drawn across the bottom left of the artwork.
  • Butterfree: ""d" Edition Butterfree". Due to a little obstruction, a large number of 1st edition Butterfree cards were printed with an ink hickey in the 1st edition stamp making the 1 look like a perfect "d". This is probably the most mass produced and most common error in the TCG.
  • Eevee: Due to an ink bubble error, a number of Eevee cards were printed with a ink bubble inside the 1st edition stamp. Sometimes referred to as "d" Edition Eevee as this error closely resembles the "d" Edition Butterfree error card.
  • Exeggcute: A number of unlimited Exeggcute cards were printed with a green ink dot at the top of the card.
  • Venonat: A number of 1st edition Venonat cards have a dark line running along the top half of the left side of the card where the yellow border meets the green background.
  • No Symbol Errors: In an early print run of the Unlimited Jungle set all 16 holofoil cards were printed without the Jungle Set Symbol.

Uncorrected Errors:

  • 1st Edition Electrode: Every 1st edition Jungle Electrode has the image of Base Set Electrode.
  • Rapidash and Seaking: Seaking and Rapidash are Stage 1 Pokémon but the text tells the person playing the cards to "put XXX on the Stage 1 card". This error applies to both 1st and Normal Edition sets.
  • Nidoran♀: Nidoran♀ is misspelled as "Nidoran ♀".
  • Japanese Jungle Holofoil cards: All holofoil cards with an evolution box have the holographic overlapping the bottom on the evolution box.

Variants incorrectly regarded as errors:

  • Electrode: The Jungle 1st edition nonholo Electrode was accidentally designed using the Base Set Electrode artwork. This was never corrected within the 1st edition print run and is therefore not a desirable error.

Fossil

Corrected Errors:

  • 1st Edition and Unlimited Holofoil Zapdos : A number of Fossil Holofoil Zapdos cards have a space for the evolution box punched out of the Holofoil, even though Zapdos is a Basic Pokémon. All 1st edition cards have this error as they were never corrected, while less than half of the unlimited prints were corrected. The corrected unlimited are somewhat rarer than the error version.
  • 1st Edition Non-holo Zapdos : Some 1st edition non-holo cards have a small red dot directly above the Poké Ball on the back of the card.
  • Haunter: A number of unlimited holo Haunter cards were printed with a purple-blue ink stain with varying severity in the lower right hand corner of the artwork.
  • Hitmonlee: Some Hitmonlee 1st edition holo cards were printed with an orange stain with varying severity on the left side of the card.
  • Haunter: A number of Haunter 1st edition holo cards were printed with an orange stain with varying severity on the left side of the card, much like the previously mentioned Hitmonlee, though much rarer.
  • Seadra (Italian): Some unlimited print cards had the water energy symbol within the move description shifted to the right, covering the word "assegnata".
  • Omastar (Italian): Some unlimited print cards had the water energy symbol within the move description shifted to the right, covering the word "assegnata". Omastar is much rarer than its Seadra counterpart.
  • Krabby: Some unlimited Krabby cards have an incomplete Fossil set symbol. Often referred to as "Fossil Slash Krabby"
  • Krabby: Some unlimited Krabby cards have an ink bubble covering or obscuring the word "length" with varying severity.
  • Slowpoke: A number of unlimited cards have a rather large blue ink blotch over the psychic symbol on the top right of the card.

Uncorrected Errors:

  • Slowpoke: The card erroneously reads Miki Tanaka's name as "Miki Takano", even though the rest of the cards that she has illustrated credits her as "Miki Tanaka."
  • Japanese Fossil Holofoil cards: All holofoil cards with an evolution box have the holographic overlapping the bottom on the evolution box.

Possible Errors:

  • Cosmos Holofoil Cards: Some unlimited holos were printed with the incorrect foil pattern. 99.99% of fossil holos are printed with the star foil pattern, but for some unexplained reason some holos were printed with the cosmos foil pattern instead. It is unclear if this was done in error, as test prints, or if Wizards of the Coast intentionally switched to a different holofoil. These are highly sought after by collectors.

Base Set 2

Corrected Errors:

  • Poliwrath: A few Poliwraths were printed with a blue ink dot on the top right of the swirl on Poliwrath's body.

Uncorrected Errors:

  • Seaking: Card reads "Put Seaking on the Stage 1 card" when it should say "Put Seaking on the Basic Pokémon"
  • Vulpix: This print as well as the Base set 1st edition, shadowless and 1999 unlimited versions of this card have their HP listed as "HP 50" instead of "50 HP". This was finally corrected in the 4th base set print released exclusively in the UK where the card's HP reads "50 HP".
  • Nidoran♀: Nidoran♀ is misspelled as "Nidoran ♀".
  • Nidoran♂: Nidoran♂ is misspelled as "Nidoran ♂".
  • Wartortle: W stamped promo versions of the Base Set 2 Wartortle have a smaller Water Energy symbol next to their HP.

Team Rocket

 
Dark Golbat reads as "Pokémon.Apply"

Corrected Errors:

  • Holofoil Dark Dragonite: A number of Dark Dragonites from both the 1st Edition and Unlimited print runs were printed without the holo.
  • Holofoil Dark Arbok : A number of holofoil Dark Arbok cards were printed with the holofoil shifted slightly to the left.
  • Dark Charizard : Some Unlimited Dark Charizards suffer dramatically from heavy black ink. This error is so severe it resembles water damage. Dark Charizard's name can be obstructed, as well as the artwork and text box.
  • Charmander : Some unlimited prints suffer from a small black ink dot above the "d" in Charmander's name.
  • Smudged 1st Edition Stamps: The quality control for the 1st edition printing of Team Rocket was very poor resulting in many cards having smudged or "heavy" 1st edition stamps. The most common cards affected by this are the Trainer cards and Dark Gyarados, though it appears any non-holo card from this set can suffer from a smudged 1st edition stamp. Stamps can appear smudged, heavy, smeared, wiped, incomplete, or any combination of those.
  • Faded Holofoil Cards: The quality control for the unlimited printing of Team Rocket was also very poor resulting in many unlimited holofoil cards being printed with a light ink layer resulting in the cards looking washed-out or faded. This also results in a sort of holo-bleed affect to the right of the cards artwork. It is assumed any one of the unlimited holofoil card can be affected by this error.

Uncorrected Errors:

  • Holofoil Dark Arbok and Rare Dark Arbok (1st & Normal Edition): Dark Arbok was printed with the number three accidentally inserted into 2000, so it was written as "©1999-23000 Wizards".
  • Holofoil Dark Dragonite (1st & Normal Edition): The attack cost symbols for Holofoil Dark Dragonite are not centered.
  • Dark Golbat (holo and non-holo): The English Pokémon Power mentions "Apply Weakness and Resistance", while in the Master Rules Document, the Japanese Dark Golbat's Pokémon Power says "Don't apply Weakness and Resistance." There is also a lack of space between the words "Pokémon" and "Apply". (Reads "Pokémon.Apply")
  • Non-Holofoil Dark Vileplume (1st & Normal Edition): Non-holofoil Dark Vileplume have a weakness to Fighting instead of Fire.
  • Dark Rapidash: Dark Rapidash's stats lack the word "Length".
  • Grimer: English Team Rocket's Grimer's Poison Gas attack puts Pokémon to sleep, although the Japanese version Poisons them.
  • Dark Raichu (1st and Normal Edition): Dark Raichu's Evolution Box is colored light gray instead of dark gray. Additionally, the card reads "Put Raichu on the Basic Pokémon" instead of "Put Dark Raichu on the Basic Pokémon". This wording error was fixed for the Legendary Collection reprint.

Gym Heroes

Uncorrected Errors:

  • Rocket's Scyther: In all prints of this card the attack Shadow Images it reads "Whenever Rocket's Scyther is attacked, your opponent flips a coin. If tails that attack does no damage to Rocket's Scyther. (Any other effects of the attack still happen.) This effect lasts Rocket's Scyther takes damage (or is Benched or is evolved)." The error with this card is the text "or is evolved" is completely unnecessary. This card was released way before gen 2 and there is no Rocket's Scizor in this set. There was a Rocket's Scizor released later as a promo but that is a basic card therefore that rule is never applied or used.

Cards of interest:

  • Blaine's Charmander: The Charmander in this artwork has a little spike on its back from its very first design. Though not an error, this specific design of Charmander is not seen anywhere else in the TCG except for the Gym Challenge expansion.

Gym Challenge

Corrected Errors:

  • Blaine's Charizard (1st and Normal Edition): 1st edition and Unlimited prints of these cards have a Fighting-type symbol instead of the Fire-type symbol. 1st edition prints never received a correction whereas unlimited did receive a correction very late in the print run. This makes the corrected unlimited Blaine's Charizard rare and more desirable among collectors, rather than the error version.
  • Rocket's Minefield Gym (1st and Normal Edition): 1st edition and unlimited prints of this card do not mention how many damage counters are needed to put on a Pokémon. 1st edition prints never received a correction whereas unlimited did receive a correction very late in the print run. This makes the corrected unlimited Rocket's Minefield Gym rarer and more desirable among collectors, rather than the error version.

Uncorrected Errors:

  • Misty's Seel (1st and Normal Edition): All prints of this card have a transparency error; there should not be a white space around Seel's tail.
  • Giovanni's Pinsir (1st and Normal Edition): Pinsir's "Snapping Pincers" attack is supposed to do 20+ damage and not 10+ damage.
  • Giovanni's Nidoran♀ : Nidoran♀ was misspelled as "Nidoran ♀".
  • Giovanni's Nidoran♂ : Nidoran♂ was misspelled as "Nidoran ♂".

Cards of interest:

  • Blaine's Charmander: The Charmander in this artwork has a little spike on its back from its very first design. Though not an error, this specific design of Charmander is not seen anywhere else in the TCG except for the Gym Heroes expansion.

Neo Series

Neo Genesis

 
Focus Band has a white bar below its picture, due to a presumed misalignment.
  • Meganium (1st and Normal Edition): The Pokémon Power title text is black instead of red.
  • Typhlosion (1st Edition): A red dot can be found left of the Neo Genesis set symbol on some prints of this card.
  • Typhlosion (Japanese): Most Japanese copies of this card have a damage number of 60 instead of 60+ for the Flame Burst attack. (The corrected 60+ version is less common to find.)
  • Slowking and Typhlosion (1st and Normal Edition): These cards' damages are off the center.
  • Horsea (1st and Normal Edition): One of the attack cost energy symbols for its attack is oddly off.
  • Natu: Energy symbols for attack are moved to left margin
  • Pikachu: Pikachu’s Quick Attack should only deal 10 damage on heads, not 20 damage.
  • Focus Band (1st and Normal Edition): The picture on the Focus Band has a white bar beneath it, apparently due to being improperly positioned during the card's design process.

Neo Discovery

  • Poliwrath (Normal Edition): Some prints of this card have a smudge-like holo bleed on the bottom left of the border of the holo.
  • Holofoil Scizor and Rare Scizor (1st and Normal Edition): The attack's damage done is "20+" while it's supposed to be "20×".
  • Umbreon (1st and Normal Edition): The Psychic symbol in Umbreon's resistance is bigger than normal.
  • Kakuna (1st and Normal Edition): The copyright text of all other Neo Discovery cards is "©1995-2001", but for an unknown reason, this card's copyright is "©1995-2000".
  • Unown O (1st and Normal Edition): The first sentence of its Pokémon Power reads "Once during you turn" instead of "Once during your turn".

Uncorrected Errors:

  • Scizor For all versions of this cards the Double Claw attack was printed 20+ when it was meant to be 20x like the wording reads "20 damage times the number of heads."

Neo Revelation

  • Delibird (1st and Normal Edition): The energy cost for Delibird's attack is off the center.
  • Raichu (1st and Normal Edition): For an unexplained reason the "Put Raichu on the Basic Pokémon" text on the card is unnecessarily bold and italic.
  • Zubat (1st and Normal Edition): Zubat's resistance lacks the "-30".

Neo Destiny

  • Dark Croconaw: The card's Pokédex entry states that Croconaw has 49 teeth, but it only has 48.
  • Dark Exeggutor: There is an unnecessary letter C in Exeggutor's name.
  • Dark Haunter: Dark Haunter's "Call Back" attack's clause leaves out the word "opponent's".
  • Light Flareon: The "b" in "benched" is not capitalized.
  • Togepi: The "before applying Weakness and Resistance" text should be in italics.
  • Unown C: Unown C's "Chase" Pokémon Power adds an unnecessary "Apply Weakness and Resistance" even though the attack does not inflict damage.
  • Unown P: There is an extra space in the Basic Pokémon title on Unown P.
  • Gligar: The energy symbols on Gligar are not in the correct position. Also, in the description beneath the picture the Pokémon Type is missing the "n" from Flyscorpion. This applies to both 1st and Normal Editions.
  • Shining Tyranitar: The word "just" is spelled wrong. It is written as "hust".

Legendary Collection Series

Legendary Collection

  • Reverse Holofoil Exeggcute: Normally on Reverse Holofoils the Energy costs for attacks aren't reflective. On Exeggcute they are. Wizards of the Coast attempted to correct this error which resulted in a holofoil shift. The attempted correction made things worse. The shifted foil variant is much rarer.
  • Holofoil Dark Raichu: Electricity on the tail is holofoil, which is inconsistent with the original Team Rocket illustration. This misprint causes the tail of Dark Raichu to look disembodied.
  • Nidoran♀: Nidoran♀ is misspelled as "Nidoran ♀".
  • Nidoran♂: Nidoran♂ is misspelled as "Nidoran ♂".

e-Card series

Expedition Base Set

  • Alakazam: The "This power can't be used if..." text is italicized while it is not supposed to be.
  • Dugtrio: Its Attack Energy Costs Symbols are larger than the standard size.
  • Gengar: Gengar's Chaos Move Pokémon Power game text has a few spots where the text could go up a line.
  • Charizard: This card tells the player to "Put Charizard on the Basic Pokémon".
  • Totodile: When Cyndaquil's card is scanned with the e-Reader a "Cynda!" sound is added to the Melody Box. Totodile being scanned, however, adds "Wani!" rather than "Toto!". As Chikorita and Pikachu (two other cards which received this effect) have the same English and Japanese names, it is unknown if Totodile's was the error, or if Cyndaquil's is.
  • Energy Removal 2 and Multi Technical Machine 01: When these cards are scanned with the e-Reader, the TM01 card names the card's move as "Paralyzing Stare" (on the card, it is "Paralyzing Gaze"), and the reader refers to "Energy Removal 2" as the ordinary "Energy Removal".
  • Darkness Energy: The card text implies that it can add to damage done to benched Pokémon, which normally cannot be increased.

Aquapolis

  • Crystal Nidoking: The Crystal Type Pokémon mentions Grass/Lightning/Fire energy, but the Crystal Nidoking's attacks only use Grass/Lightning/Fighting energy.
  • Reverse Holofoil Lanturn: There's a Poké-Body icon on it for no specific reason at all.
  • Magnemite: The text on this card is quite faded as opposed to other Metal Pokémon in the set.
  • Ariados: In its Spider Force attack, it should say "Defending Pokémon", not "defending Pokémon". This error is not present in the non-holofoil version.
  • Nidoran♂: Nidoran♂ is misspelled as "Nidoran ♂".

Other/Promotional cards

Wizards

 
Prerelease Raichu
  • Prerelease Raichu: Arguably the rarest card printed by Wizards. Rumored to have been about 6 to 50 made, some of which were retrieved by Wizards themselves. These cards came about during the printing of prerelease Clefable from Jungle, when some Base Set Raichu cards were attached to the side of sheets of Clefable cards. Wizards staff denied their existence for years, but have since confessed to the card's existence.
  • Pikachu: Due to a mistake by Wizards, a few Ivy Pikachu promo cards were printed with a 1st edition stamp. This is the rarest unique card in the 1st edition series; it is said to be found in only 1 of 10 Jungle booster boxes.
  • Pikachu: The Japanese Glossy version and Portuguese Pikachu World Collection 2000 version both erroneously credit Ken Sugimori as illustrator, instead of Keiji Kinebuchi.
  • Electabuzz / Mewtwo / Pikachu / Dragonite: These four promotional cards were accidentally printed with the Pokémon the First Movie logo upside down in the lower left corner. It is thought that only 30 of each card were printed with this error (so a single misprinted sheet of 120 cards).
  • Meowth: The HP is nudged too far over to the left, and the attack cost symbols are much smaller than the normal cost.
  • Eevee: Promotional Eevee's Pokémon Power text lacks the accent mark (it's e instead of é).
  • Dark Persian: A number of Dark Persian were printed without any HP.
  • Team Rocket's Meowth: Team Rocket's Meowth category is listed as "Scratchcat" instead of "Scratch Cat".
  • Marill: Its "Length" stat is listed as "Height" instead of "Length", its Water Gun attack is missing a Water energy symbol and its 20+ damage done is off the center.

  • Mew: Mew's attack: "Psyshock" inflicts confusion instead of paralysis.
  • Celebi: The art is credited to "Hajime Kusajim," a misspelling of Hajime Kusajima.
  • Slowking: Slowking's length is listed as 6' 8" instead of 6' 7".
  • Promotional Hitmonchan: Hitmonchan's HP is written as 60 instead of 70. Some of these cards were intentionally released with this error by Wizards of the Coast at the time as their license for printing Pokémon cards was ending around the time the Best of Game TCG was released.
  • Moltres / Articuno / Zapdos: The first print runs of these cards erroneously credited the illustrator as Toshinao Aoki instead of Naoyo Kimura, which was corrected in later prints.

Nintendo

  • Ancient Mew: When it was first being printed in Japan, the copyright text was misspelled "Nintedo" instead of Nintendo.
  • Various cards: Some cards will have square edges or a mix of round and square images.
  • Various sets: During the printing of sets, there is a rare chance that a card in the set will not get printed correctly. This results in the border being partially visible and the rest of the card being a blank white box. These cards are usually sought after by collectors.

  • Pikachu: Numerous cards were printed with the back printed upside down.

SWSH Promos

  • Pikachu: Some of the General Mills promo version of these cards have one to several red dots printed on them. The most common appears to be a red dot under "HT" and another red dot on the top right border.
