jeffbuckes Pillar of the Community United States 834 Posts	Posted 01/07/2019 3:43 pm My guess: clad or laminating damage to the planchet before striking which might have caused the zinc coating to corrode. It was the first full year of production for the "zincolns" after all. I'm sure other members know more than I do. Report this Post to the Staff

Please use them in the future. * At first I thought something like that, but in the circle in the middle almost looks like what could be a roman numeral. It is in an 1983 Olympics Mint set. It has been sealed in that setting, and never opened sinced purchased. I thought if it was damaged surely collectors would have seen something similiar. Or, if it is marked surely someone has seen it. I am hoping for a definitive, so I hope some member sees it and recognizes it. Thanks for your response. Report this Post to the Staff
Conder101 Bedrock of the Community United States 17884 Posts	Posted 01/08/2019 08:11 am It is corrosion from a foreign body that was laying on the surface of the cent when it was packaged. And yes we have seen this alot. One thing that can cause this is a droppet of saliva or "spittle" that settled on the coin. Report this Post to the Staff

jeffbuckes Pillar of the Community United States 834 Posts	Posted 01/09/2019 4:27 pm @Klk - It's not "worthless", but it is "worth less"... The set usully sells for about $40.00, but the damaged cent makes it worth a bit less. You won't know until you try to sell it, but I bet you could get $30 for it... Report this Post to the Staff
