Been there, done that!
I have more than 10,000 BUFFALO nickels, ranging from junk to UNCircs...! Actually, my GRANDchildren own them now, but they are still in my possession. Unfortunately, all mine have four legs!
I bought something at a 7-11 about six months ago, and the change immediately caught my eye.
There was a Buffalo nickel in it!! 1942, IIRC. I stuck it in a coin jar I have for wheat pennies, etc.
