Looking to buy a fox, fisher and coyote pelt from someone and he said the coyote and fox are 5 years old, though they look fine to me. Fisher is only 2, so I'm not too concerned. I am wondering if it's worth it to purchase them, as I'm wondering how long they will last? I have pictures of all pelts, front to back. (He wants 250 for all three, which I think is a pretty good deal.)
