I have a 1955 Penny but its rely odd it has a weird shiny soft goldish looking metal tone almost like white gold i cant explain it ill try to get photos up maybe a experimental metal
2 possibilities,mercury coated,or plated.doesnt look like anything valuable,we have seen alot of these posted in various years.sorry
those dents could have been there before it was plated (if it was). Can you weigh it? it should weigh 3.11 grams of near there.
Looks like the ones we used to chrome plate in Auto Shop. I will post a pic of one, as soon as I can find it.
