HK 694A
Quote from StevenG on June 26, 2011, 4:31 pmI sent in an HK 694A recently that has a white, chalky appearance. NGC wouldn't even give it a Details and sent it back without encapsulating labeled Environmental Damage and "Not Suitable For Certification". Has anyone else had trouble getting one of these graded? What did the original White Medal version look like? The guy I bought it from scratched the edge and concluded that the silvery metal is zinc. Does zinc age strangely?

Zinc can form a white zinc carbonate coating that is somewhat protective against further corrosion and a white zinc sulfide that further deteriorates the surface forming pits when it is removed.
