The pelt's price will reflect the quality of the fur and the quality of the skinning job. A mountable bobcat pelt can go anywhere from $100-$500 (and highballing $700 though good luck finding a buyer), fully tanned, split and mountable with claws and pads still attached.
Coyotes are a bit lower, ranging from $60-$250. $60 quality usually has the legs cut off and is considered a wall hanger. Higher priced pelts are mountable.
It all depends on how its skinned, how well its skinned, what quality fur and what type of tan it has.
