I think it was coop that said it was from a cigarette lighter so PMD. I am leaning,(just a bit) towards a plating issue. I have a few of this type of whatever it actually is,just in case. John1  |

Thanks John1, It does seem like there is some controversy involving this type of plating issue. My guess would be the plating was thin and when the die struck it was heated enough to break down this thin layer of plating. They don't seem that scarce so probably not worth too much fuss.

I "think" I remember seeing one in a NGC slab if that helps any. John1 |

what's left of the copper looks pitted/flaked to me which would indicate it was more likely "de-plated" PMD. Partial or incomplete plating generally looks pretty obvious as a portion of the coin doesn't enter the plating solution at all and therefore can't get plated. This doesn't appear to me to be a chemical de-plating using a corrosive though that would be easy as it distorts the details quite a bit, but it does have the appearance of reverse electrolysis. where the copper is slowly "de-plated" from the coin and back into a solution, the same way it was plated. just my opinion of course, good day. |

 with John1. There's too many coins with that problem. Even though it does look like a cigarette lighter could have done it. |

My wonder is How is it partially plated in center of the coin? Most all I have are in center of the coin obv&rev or just one side.  .  |

I would not agree with NGC on that one EXCEPT the zinc is so clean and silvery still. I mean you can't argue the zinc on the MS66 NGC one isn't "mint state" as it left the mint after being struck. the OPs coin,,,, a lot could have happened to it since leaving the mint and the darkened exposed zinc doesn't help to make the case of it being a partial plated cent as it left the mint. it's like the Presidential dollar coins that are missing the edge lettering, pretty worthless once it's circulated and could have been worn off the edge, but still in mint state it clear it couldn't have "worn off" or been removed the tampering would be evident. Good luck with it. |
