All the coyotes our group shoots go to my dad who is a licensed trapper. In southern ontario, he they seem to go from $10 to the extremely high end of $80 (but rarely). He also traps them, but when you ship them, you can't tell which ones got which price. I think a few years ago, he shipped 90 or so and averaged around $20. He is retired and spends around 3-4 hours on each one, skinning, sewing up bullet holes, trying to get most of the blood out, stretching them, turning them, shipping them etc.
At $10-$13 for a muskrat, and sell the meat for a couple bucks, he would rather have 100 of them....
Also keep in mind, in Ontario, you can ship and sell to the fur companies on your small game license, but the cheque you receive is considered income and is subject to taxes and reporting. If you trap as a business, then you can write off supplies, fuel costs etc to balance this out.
One of the guys in our group is convinced that we are giving away thousands in fur, that it is easy work for big bucks. Not from what I've seen.
