Did they make a 1944 experimental alloy coin? I found a 1944 silver penny that weighs 3.5 grams and after an extensive Google search that is all I can come up with. The coin will not stick to a magnet, so it is not steel. I will post pics when I return home.

Normal weight for the copper planchets is 3.11 grams.
Normal weight for the steel planchets is 2.7 grams.
Normal weight for the zinc planchets is 2.5 grams.

I know, but I found on the internet where they experimented with a new alloy. It said most of the coins were destroyed, but some were circulated. These coins were heavier and thicker, just woundering if anyone has knowledge of this?

I would agree this is most likely a copper coin plated with Nickel, this was a common experiment in high schools and for garage chemists.
