A valuable item is an item which generally serves no practical purpose other than to be sold, usually for a high price.
In Generation II and IV, it is possible to buy some of these items for a discount (but only one of each per day) on Mondays in the morning in the Goldenrod Tunnel. In Pokémon Black, some of these items are sold in Black City, albeit for prices much higher than they can be sold for. Often, these items later become exchangeable items. In Generation V, mulches and flutes became valuable items due to losing their function. While most of these items can be sold at Poké Marts, those introduced in Generation V can only be sold to certain item maniacs. Besides Big Nuggets, Pearl Strings and Comet Shards, the player can also sell normal Nuggets, Pearls and Big Pearls, Stardust and Star Pieces to the maniac inside the Icirrus Pokémon Center, for double the price presented below.
The SlowpokeTail is actually a useless item with no function past its monetary value. Although it is said that a Slowpoke will use its tail for fishing, a SlowpokeTail has no effect on fishing at all, nor does it have any effect on Shellder despite the fact that contact with a Slowpoke's tail usually induces a spiral change.
The first time that humans eating Pokémon is mentioned explicitly in the games is when a Team Rocket member mentions the SlowpokeTail's value as a delicacy. In Pokémon X and Y, Slowpoke Tail is one of the dishes served by Restaurant Le Yeah in Lumiose City.
The Japanese name for nugget, きんのたま kin no tama, literally means "golden ball", which is also a colloquial term for testicles. The man offering his "golden ball" is a frequent joke amongst Japanese fans. As this pun would be lost in translation, as well as the fact that it would not go over well with parent groups, it was translated as "nugget of wisdom".
The Rare Bone and Thick Club share the same Bag sprite.
