Gonna make another practice diagnosis. Please don't rely on my opinion. Wait for a CT expert. I would like to have clearer photographs, but here goes: I am going to say that what you see plating split doubling evident on the reverse in"UNITED STATES" and "ONE CENT" and maybe die deteriorated doubling on in "e.pluribus unum" but I can't see that very clearly. Oh! I must have gotten this one wrong. I will wait for one of our CT Experts to fail me!
