  1. I just came here to say pennies aren't copper anymore. They stopped making pennies out of copper in 1982. If a penny was made out of copper today it'd be worth about 3 cents. Now you can argue that the mint makes up for that shortfall when they print twenty dollar bills but that's not how they see it. The copper plating is pretty thin so you can scrape it off and see the base metal that's inside of a penny. It's zinc.

  3.  @LibertyDIY  if you cut a penny in half it's really obvious there's some grayish pot metal in them. I think it's zinc?
