Mark1959 Pillar of the Community 7234 Posts	Posted 09/10/2017 9:44 pm If you are talking about the silver colored areas it's probably split plating - Not an error. When the coin is struck the pressure of the strike tears the copper plating and exposes the zinc underneath - very common on the Zincolns. Report this Post to the Staff

PennyPride Valued Member United States 84 Posts	Posted 09/10/2017 10:10 pm But I was pretty sure that it was just Machine Doubling. Report this Post to the Staff

It can be addicting looking at your coins under it. You'll have lots of fun If you can, get one that has an adjustable light source. Mine doesn't and I wish it did. Have fun!
