ZeroC11 New Member United States 12 Posts	Posted 02/05/2025 12:39 am I have two 1999 S Proof Sets that I am seeing some odd discolorations on multiple coins, on top of what seems possibly doubled as well. I only have pictures of one of the pennies that the ear seems maybe doubled. Could just be from looking through the set cases. Report this Post to the Staff
