OMM's stopped in 1955 so it can't be that. Looks like split copper plating with these pics. Maybe DDD, but it is a plating issue for sure. John1  |

@jul, when I crop, enlarge, and enhance your pic, I think I'm only seeing damage to the mintmark. As mentioned above, a better closeup would definitely help to confirm though.  "If you climb a good tree, you get a push."

I'm thinking early emergence of split plating--not terribly uncommon with 1980s and 90s zinc core cents.

I agree with the split plating diagnosis. The metal will continue to separate eventually exposing the zinc which will then bring on zinc rot. Zinc rot is the eventual fate for all 821/2 zinc cored cents. Spend it now to avoid heartbreak later.  |

We will need better up-close photos to really tell what is going on here.To me it looks like the copper plating around and below the date is "loose" like it did not adhere properly. That is why the MM looks damaged.May not be split plate,can't tell for sure if there is zinc showing or not. John1 |

@data, John1 is correct, there is "plating" involved. And it does split. And you knew what we were making reference to, n'est pas? Mike Diamond is correct with the proper terminology, but "split plating" is just a shorter term for the same issue. |

This could, in theory, be an RPM as the mint mark was still being hand punched into the cent working dies in 1988 (and 1989 as well).
I agree this is far more likely to be a plating issue however.
If the OP is confident of seeing a 'S' in that blob I politely suggest that is simply a case of the mind connecting random shapes into something resembling order - like seeing a clown in the clouds. There is a word for this visual phenomena but it escapes me at the moment.

The proper term is "split plating doubling". There is no "plate" involved
How is that possible when it is a copper plated zinc core cent? Yes I'm personally aware that when people here use "split plating" or such they are referring to that error. I was just posting some of the other info related to the error for others to read or learn, including that quote that mike diamond made here about the correct terminology for this error: http://goccf.com/t/357614#3416319 Looking at the other replies from that thread again, he was likely replying to the person who called it "split plate doubling". As to the coin its just easier to identify if you can see the zinc coloring which you can see in the other two examples I posted. I'm learning like everyone else just trying to share as I go if that helps others to also learn. We all have our own individual personal strengths and weaknesses of our knowledge.
