It should be a zinc-coated steel but I think all the zinc on this cent is gone. The coin is rusting and must have been sitting in some awful liquid.
Actually found two of them at the same time it must have been dumped together because it has the same rust pattern.
Here's the stats...
Type/Country: 1 Cent / United States
Metal: 100% Steel and plated with Zinc
Value: $0.10 in G-4
Do you have a cent and
want to know its value? Leave a comment/question and I will do my
best to find out the price and history for you.
