    I'd call it an RPM, but since they started making the mint mark part of the die in 87..I think, it wouldn't make sense in the way I understand it anyway. I can hardly wait to to find out what happened, I'm sure someone will know lol.

    Probably machine doubling. Note that the same doubling is also visible on the numbers of the date.

    It appears to be machine doubling....Cheers, RickO

    Just curious, do you normally see split sheriffs with machine doubling? Although I have learned much in the past year or so, I am still learning. The thing I found most interesting is in the second to last photo where you can see what looks like the original placement of the mint mark and looks like it shifted downward, but how could that happen when its the only device to show the anomaly? When I saw it, my immediate thought was, I need to ask you experts to get an understanding. Thank you for your time and expertise in teaching an old dog new tricks lol.

    Looks like MD. Real nice pics!.

    Looks very flat and shelf-like, which is a key sign of MD.

    Also, this sort of "ghosting" is commonly seen especially on zinc cents. MD, die wear, both, etc.

    I saw the shelf like MD, but also the split serifs. What Im most curious about is the mint mark. Second to last picture I think shows it best where you can see the imprint of the back of the D as like that of the D is doubled/trippeled and the top of the D is peeled back like a can opener. It just looks like the MM was at a crazy angle and then adjusted into place. That said and knowing they don't punch MM any longer, makes me extremely curious what made this happen, I don't even know what you might call it to look it up. How does a die create what happened to the MM?

    You see this kind of thing all the time with the modern copper coating of the zinc. The copper doesn't seem to bond really with the zinc and moves or squishes when struck inducing lots of MD, split plate doubling, and ghosting. Add some die wear into the equation and these are a mess, while interesting this is just MD and not some type of double die.

    I will take your word for it, and look for others that may be like this one, thats a crazy sight! It really looks like the D was at a completely different position and shifted into place.
    Thank you! I need to study on that one more.
