Ladies and gentlemen I'm going to take a stab at this and say this is an s over d in the mint mark. I want a variety Vista Air relief even copper coin found nothing close I'm sure you people have a sight that I can check out even if you tell me yay or nay I'll still go check it out thanks
IMO it was either a damaged punch or a plating issue of the zinc coating over the steel. I cant find any examples of a 1943 OMM
Many anomalies including nicks, marks, and gouges on 1943 steel cents. You got a strange one there. Seal it, show it, and enjoy it. Thanks for sharing!
