Not sure what you mean. Are you talking beaver hides or carcasses for use as bait. I have a couple hides in the freezer but not dried and I hate to try to put them up this time of the year. Pretty much all beaver are cheap so I'm not sure how the price could go much lower and still be worth fooling with.
there are some for sale down town portland oregon but you might catch somthing
One thing, most NWCO use the banned traps on a special permit and as such CANNOT sell or trade or receive anything for pieces or parts of those trapped beaver. Just a thought.
