Looking through some stashed coins and spotted this. It looks like a lamination error and maybe a RPM. What do you see?
rockdude: No, unless your pointer is in the wrong place. The lamination is (or appears to be) behind the 3. Also, POSSIBLY, beneath the 5. [could be postmint damage, but hard to tell.] And, it doesn't appear to be an RPM.
And I think the 52D is (1952D-1MM-025) It has the same split serif on the bottom and that variety indicates it was damaged by a mintmark punch. May be you should check out the die markers to confirm.
OK, thanks all. I just checked out the '52 and it's a -019 markers match, thanks jessash1976 for looking at those, it's always a pain to find the right one. The '53, the mint mark is the wrong location for -018. Looks like the lamination error on that one. Forgot to ad that the die chip is not in the photo at coppercoins. Later die state.
