Julesie4558 Valued Member Canada 50 Posts	Posted 02/03/2023 7:49 pm I know that there is an RPM error for the 1988 D but this looks undeniably like an S to me. I am biased though and would appreciate hearing other opinions :) Report this Post to the Staff

Dearborn Moderator United States 97433 Posts	Posted 02/03/2023 8:01 pm a very common area on zinc cent coins for plating problems. Collecting since 1972. Learning from then on "Tell me and I forget.

John1 Moderator United States 56855 Posts	Posted 02/03/2023 8:06 pm 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 Report this Post to the Staff
Spence Moderator United States 34428 Posts	Posted 02/03/2023 8:20 pm @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.

ijn1944 Bedrock of the Community United States 19208 Posts	Posted 02/03/2023 8:44 pm I'm thinking early emergence of split plating--not terribly uncommon with 1980s and 90s zinc core cents. Report this Post to the Staff
merclover Bedrock of the Community United States 10635 Posts	Posted 02/03/2023 9:36 pm 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. Report this Post to the Staff
datadragon Pillar of the Community United States 1648 Posts	Posted 02/04/2023 12:18 am The proper term is "split plating doubling". There is no "plate" involved posted by mike diamond by the way. Here is an 1988-D with split plating doubling where you can see the zinc showing. http://goccf.com/t/357614#3362884 and another from another year http://goccf.com/t/437598 split plating doubling is restricted to copper-plated zinc cents. https://www.error-ref.com/split-plating-doubling/ Better photos can help compare to those.

John1 Moderator United States 56855 Posts	Posted 02/04/2023 04:12 am 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 Report this Post to the Staff
Julesie4558 Valued Member Canada 50 Posts	Posted 02/04/2023 9:23 pm I don't know if these are any better. I've got MS so a steady hand is definitely not my strong point. Lol Report this Post to the Staff
John1 Moderator United States 56855 Posts	Posted 02/05/2023 04:12 am Sorry, those pics are no better.We need up close in focus pics. What are you using to take pics? John1 Report this Post to the Staff
merclover Bedrock of the Community United States 10635 Posts	Posted 02/05/2023 04:27 am @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.

nickelsearcher Moderator United States 15485 Posts	Posted 02/05/2023 05:37 am 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. Take a look at my other hobby ... http://www.jk-dk.art Report this Post to the Staff
