Sorry for taking your post in a different direction John!
I went to our state furharvesters convention back in September and one of the larger fur buyers in the Midwest gave a price break down on different things from different regions. You might check on their website, Petska Fur. I know they are going to run routes all the way south into TX this year. Seems like he said for your area $20 average on your better coyotes, (big, no damage, no mange, etc).
I have a nuisance beaver or 2 to remove this winter as well. I am not sure if you can even get a buyer to buy a beaver hide this year. You can always have them tanned and sell them as decor. Heck I almost forgot the castors! I know a guy who sent some beavers to one of the big auctions in Canada last year actually got more for his castor than the hides!
