Once an while, a few oddities larger critters skins are sold through NAFA and I suspect most go to taxidermy work. I'm pretty confident that a mt. lion skin could be sold if it was legally taken in BC but there would probaby be reams of paperwork. It could also probably be sold to someone here in the states but I'm sure both governments would take their cut (don't they always, the never ending hunger!). A guy would have to price in those kinds of costs.
