To me it looks like a single squeeze die doubling and I compared it to another I have and the ear looks enlarged.
I'm usually wrong about this but figured "maybe... Just maybe" lol. I'm guessing a hit to the ear since it looks fairly large for doubling



Or is this just a die chip under the ear? Gahhh it bugs me that I can't look at the doubled die listings for nickels, wexlers dosnt have the link active to it so I can't check listings for these
