I don't have any experience but my mother does (if I could just get her to post here!). I'm sure all the advice here is great, so I don't know if this will add much. My mother has made teddy bears for people out of old fur coats. She said you have to be very careful because it's essentially very fine, thin leather. Use as few stitches as possible so you have as few holes as possible. She spoke of using a 'ladder' type stitch that more joins the pieces together like butting it together, than a typical lay two sides together and turn it right side out. As someone suggested, looking inside the coat will probably give you the most information! I believe she also used a blunt needle to hand pick out any hairs that got stuck in the seam, once they're pulled out, you can't hardly find the seams.
