Minnie Mouse plushies have been produced since the early 1930s. That's 80 years! So, no, there is no master list that I'm aware of.
I've been collecting stuffed animals since the day I was born! I've never counted my collection, but my guess would be that I have somewhere around 2-3 thousand. Over half of that is Disney. A lot of my collection has come from garage sales and thrift stores. You can find a lot of awesome stuff second hand. I once found a 101 Dalmatians plush that I believe is a prototype.
Start small. Just buy what you like. Don't worry about trying to get them all. If you're a "completest collector" try focusing on completing sets. Personally, I would
LOVE to have a 1930's plush Mickey or Minnie, but they go for insane amounts of money. Last I heard it was somewhere around $10,000.

I have dropped a LOT of money on stuffed animals, but no where near that!
Good luck with your collection!
