There is a section in both Fur Fish and Game and Trapper and preditor caller Magazines. They are estimates and just like the stock market they can fall or rise.

Last year I sold my early beavers for about an average of $28 but my late ones which had much better fur went for an average of $15. I sell at auctions becuase you can get more with several buyers bidding on them. Don't expect to make money trapping. It a great a fun expierance. It is very addicting. Just driving down the road I am always looking for spots to trap or animal sign. I believe it also makes you a better hunting and woodsman.
