I have a penny from 1974. It has a dull silver like color. I tried to look for information, but I could not find anything on this coin. Does someone know if there were any zinc, steel plated or silver like pennies struck in 1974? I have kept this coin since it seems rare and was hoping to find something on it. Please write to me at fernandesjones@yahoo.com if you can help.
If its weight and diameter is normal, then it's almost certainly plated. Or perhaps it was dipped in mercury.
