Can anyone please offer some information on copper nickels which each weigh 5 grams? they are from 1980 Denver mint. Thank You Very Much, Error66.
I don't think those are made of copper. Could be environmental damage. If they were struck on a copper planchet they would be the same size a Cent. It looks like a normal Nickel sized planchet.
Thank You Paddyman98. They weigh 5 grams each, but I do not believe that they ever received the final clad. Yes, environmental damage sounds about right. I greatly appreciate your response and knowledge. ~Jim
Nickels are not clad, they are a solid alloy all the way through. These coins are just environmentally damaged.
