Rare authentic american bison bi-fold wallet with push down clip

I have seen many of these wallets but none with a clip like this one. Also. The bison/indian head quarter is one of the best known collectible coins. I have seen them from 25 to 65,000. But since we cannot see the front of coin im taking the chance of letting go of priceless coin. My hard times may be your lucky day. Keep it and use it as a conversation piece or cut it open and see if you got the prize winning nickel! It has weird circle on back. I cannot get it off nor figure out what it is.
