First off, you need to make sure they attribute the error. PCGS and NGC state what they will attribute and you must add it on the line item, and pay the attribution fee. I think ANACS is a lot more flexible, you can point them to CONECA or other resources and they will verify and list if they agree with it. At least that is my understanding.
I swing a metal detector and have a knack for finding dirty old coins.
