I am trying to decide which types of stuffed bears to buy for my nieces and nephews. I was thinking it might be nice to get them some collectibles since they are old enough for that now. However, I am not sure which types of stuffed animals are considered collectibles. Can anyone tell me what the most popular collectible stuffed animals are right now? I think at least one of my nieces would love to start a stuffed animal collection, but I want to choose a type that she will enjoy collecting so I want something popular with the kids now.
