Well I'm no expert, but I can tell you that the Mickey on Lil D's butt is not really the same as the one on Duffy's. His is straight, but is more level with his tail, whereas Duffy's Mickey is slightly above the tail. I'm guessing that the butt Mickey has moved around a bit with each new generation of bear. Or it may have to do with the more inconsistent craftsmanship of Disney Bear vs. Duffy. Personally I wouldn't worry too much about him being a fake. He looks good to me and I'm sure he'll make a nice addition to your bear family.
