There are several series of these cards produced by Upper Deck. There used to be checklist on the Upper Deck site, but they are hiding from me right now. Another good place that I use for Disney checklist is Jeff Allender's checklist site.
There are 5 series of sets.
Series 1 (2003 - Mickey Mouse Wrapper/Box) cards 1-89 + inserts
Series 2 (2003 - Donald Duck) 90-179 + inserts
Series 3 (2003 - Winnie the Pooh) 180-268 + inserts
Series 4 (2004 - Pixar) DPT1-DPT175 with 161 to 175 being inserts
Minor sets
Holiday Treasures - HT1 to HT50 + inserts
Mickey - 75 Years - Mostly the same as the Filmography cards from Series 1 - MC1-MC75
They aren't too hard to find, but watch out for the prices. There are some boxes that are starting to get pretty expensive. I put together my sets when they came out, so I haven't been buying recently enough to know what a good price is for the boxes or sets. I am working on the harder to find inserts, but if you have any questions about what the actual inserts look like, please just let me know.
