hmmm... https://www.money.org/collector/caleb/blog/1937-d-3-legged-buffalo-nickel- From the ANA site: Coins | Caleb Karling recently I have seen quite a few fake 1937-D 3 legged buffalo nickels. So here are my 5 diagnostics into determining if a 1937-D 3 legged Buffalo nickel is real. Neck of the indian The top of the neck on the indian will look really bumpy and mossy. It won't be smooth like the rest of the neck. The missing leg Look at where the leg is supposed to be and look for tool marks like a dremel, or file. The hoof of the buffalo will still be there in a genuine coin. The buffalo The body of a genuine 3 legged buffalo nickel will be significantly smaller than a regular buffalo nickel. One of the funnier ways to spot a genuine nickel (Usually in BU or better) the buffalo looks like it's urinating. Back Legs The two back legs of the buffalo will look very bumpy and rigid like the top of the indians neck. e pluribus unum The P in pluribus and U in unum can't be touching the buffalo. In order: Neck: not bumpy Hoof: Not bad looking, but... looks smaller than yours. But I could be wrong. Back Legs: Look too strong EPU: looks fine.
This is what I see: Obverse: Back of neck moth eaten appearance 3rd feather is detached Bumps on neck Reverse: MM is in correct position EPU is separated from Buffalo rear leg is moth eaten Here is one slabbed by PCGS in about the same condition
