:For the other key items, they had different sprites or index numbers. For the S.S. Ticket, they all have the same sprite, and in Generation III and IV they had the same index number (within a generation). It wasn't until ORAS that the items started to be given separate index numbers.
:Maybe it makes sense to split them. I'm not sure, but it would certainly make it difficult to link to the page from the Gen III and IV list of items by index number pages (they'd probably need to link to the disambig). --[[User:SnorlaxMonster|<span style="color:#A70000">'''Snorlax'''</span>]][[User talk:SnorlaxMonster|<span style="color:#0000A7">'''Monster'''</span>]] 14:02, 20 May 2020 (UTC)
