johnz2 New Member United States 1 Posts	Posted 04/26/2018 8:00 pm I recently bought rolls of 2018 Kennedy half dollars from the mint. One coin in the D roll was discolored. Looks as if the planchet may have not been polished as the discoloration was on both sides. The coin looks as if it has a matte finish and darker. Has anyone else seen anything like this? Picture shows darker coin on the right. Edited by johnz2 04/26/2018 8:03 pm Report this Post to the Staff

I will say that we often see darker toning on coins that have had environmental or chemical exposure. Since these coins are 2018s straight from the mint though, that explanation seems less likely.

Crazyb0 Rest in Peace 10197 Posts	Posted 04/26/2018 9:37 pm That is a "sintered" planchet. It is a mint anealling problem. Has to do with too much oxygen in the annealing ovens, causes this metal reaction, is a dulling process, not really the "Black Beauty" Coop is referring to, that is a nickel, and an alloy mix problem(most likely). or It could be a fault rinsing cycle with dirty solution, but I really would think, either one would have more examples than one, especially a rinse.
