So I was going thru a box of pennies and came across a 1992 P Lincoln Cent that looks like steel but isnt. Maybe lamination error on both sides?? Anyone know how to truly figure out if it is a lamination error or an error made after the mint??
1992 Cents are Copper plated Zinc. That's the zinc inner core you are seeing.and not steel. Somehow the copper plating was removed
Looks like environmental damage to me. Like many of the coins that have been buried for a while. JMHO
