1937-D 3 1/2 Legged Variety Buffalo Nickel ICG-Au50

I'm no expert, but I suspect ICG just labeled either an altered "normal" 1937 D nickel as a variety or perhaps it is an outright fake.
This is not a progression of the famous and authentic 1937 D three legged variety.
On the real 1937 D three legged nickel, the E PLURIBUS UNUM does not touch the back of the buffalo, where this one clearly does.
It is not struck from the authentic 1937 D three legged reverse die.

I need some help here and am not confident in ICG's attribution. Is there such a variety? I have never heard of a 1937 D 3 1/2 legged Buffalo nickel. I have heard of the 1936 D 3 1/2 legged Buffalo nickel but this isn't that reverse die either.

I suspect, this got by the "professional grader" at ICG and I wouldn't buy it until somebody enlightens me on this as a legitimate collectible variety. Be careful!
Buy the coin, and not the holder rings loud and clear once again.

I have never heard of a 1937-D 3 1/2 legged Buffalo nickel. Only a 1936-D 3 1/2 legged Buffalo nickel exists.

I think they made a mistake on the label.

I have owned 17-D, 27-D and 36--D 3 1/2 leggers (all were slabbed and labeled correctly).

This one looks like a "normal" 3-legger to these tired old eyes. Looks lightly cleaned, too.

and I would steer clear of this coin.
