You can send it back to NGC and they will do a detailed analysis of the metal composition and list the breakdown on the insert. Last time I looked...
You're all nuts. The coin has some light oxidation over pristine surfaces.
I'm not going to debate you on cause, but perhaps you could enlighten us on your answer of "putty". What mastermind would putty between the...
