Your nickel is only worth a few bucks, it's not a real "3 legs Buffalo" nickel, those were a 1937D and it's the leg on the other side of the buffalo that should be missing.
Ya that's why I say I got it the hard way lol. It's some sort of cud error or something, I'm not sure. I'll still call it a win because it technically only has 3 legs. Still not the 36d or 37d
