Possible duplicate mint marks?

Has anyone seen a 1984 penny that looks like this? It looks the mint mark was punched twice. There is also something that looks like an "o" above his tie. I am assuming that was damage, but could the mintmark

have been re-punched? I am including a normal looking 1984 D penny for comparison.

    The photo needs to magnify the mintmark area. The current photos are not clear enough to make any call.

    All glory is fleeting.
  • Ok, thanks. I took a couple of pictures with my magnifying viewer that projects onto my laptop. I hope this is clearer. I also attached a picture of the circle under his chin. Thanks

    Looks like a copper plating blister.

    For some reason, that's a fairly common
    area for this anomaly to occur.

    I agree with Fred, either plating bubble or die chips... Cheers, RickO

    Sorry, spent more time trying to figure out what was in the background reflections around the coin in the OP.
