Vintage Genuine Fur Collar

Vintage Genuine Fur Collar! I think it may be mink or beaver, not 100% sure (it’s not labeled). Has some wear on underside (I’m thinking at one point it may have been removed from a coat). All proceeds will go to my brother who has a rare kidney disease, needs another kidney transplant, has health issues & can no longer work and struggles financially. We are trying to improve his quality of life!
