I am trying to identify the error on this coin. Feedback is appreciated.

It looks more like the D took a strike. PMD. But I hope I am wrong.

Looks like the coin took a hit from another coin. If it were machine doubling it would probably follow the curve of the mint mark. But this look pretty straight. Someone you find the mint mark and date machined doubled, but sometimes just the mint mark. So I'm with WAPA on this one.

I'm gonna say a hit as well, not an RPM or mint error.
