At first you'd think the copper coating has come off but what has happened to the letters and the numbers uploaded/stevieb/20200720_SingleShot0014.jpg[/img This coin is much more graphic when you have it in your hand Report this Post to the Staff

Spence Moderator United States 34397 Posts	Posted 07/20/2020 4:59 pm It does seem like the copper plating has been stripped off, but I'm not sure whether it is through flame or chemical exposure. For reference, the melting point of zinc is about 800F while the melting point for copper is nearly 2000F. What is the weight?
