If you're in it for the $, you're in it for the wrong reason. That being said, predicting the value of fur prices is a waste of time. All you can do is trap what you can, put it up as best you can, and sell it. If it's good quality fur and put up well, you'll get your maximum price for it.
It could be one price today and something else tomorrow or one price from furbuyer A and different from fur buyer B.
