PNWHiker Valued Member United States 104 Posts	Posted 07/03/2021 3:55 pm I found this while coin roll hunting. Any ideas? I was thinking something along the lines of a D over a horizontal S. I'm just talking out my butt though Report this Post to the Staff

John1 Moderator United States 56855 Posts	Posted 07/03/2021 7:38 pm First off, OMMs stopped in 1955 or 1956 so can not be that. It looks like a platting issue. John1 Report this Post to the Staff

oddguy Pillar of the Community United States 4135 Posts	Posted 07/04/2021 10:36 am to me it looks like the d took two hits, lower right and right side Report this Post to the Staff
Greasy Fingers Pillar of the Community United States 7010 Posts	Posted 07/04/2021 11:01 am At the time of minting, the strike had a bit too much pressure causing the copper plating to split (outside lower curve of D) and now zinc rot is setting in....spender Report this Post to the Staff
Petespockets55 Pillar of the Community United States 5770 Posts	Posted 07/04/2021 11:27 am Not really any need for additional images unless you want the practice. As mentioned by many, this is a clear case of plating issues and/or zinc rot creating the effect. Check error-ref.com for a more detailed explanation with images.

PNWHiker Valued Member United States 104 Posts	Posted 07/04/2021 3:21 pm So the "rot" is causing the raised line? What exactly do you mean rot? From what I'm used to outside the Coin World, rit usually caves inwards Edited by PNWHiker 07/04/2021 3:25 pm Report this Post to the Staff
