Obverse on this coin. This coin is straight graded AU-55 but will this get worse? I have seen similar coloration on many and often it is dirt or grime but I dont think this is. Not really interested in buying this one but curious what it is. Report this Post to the Staff

fortcollins Pillar of the Community United States 3621 Posts	Posted 12/07/2021 7:07 pm The pitting on the reverse suggests corrosion, and possibly removal of the surface gunk that revealed the pitting. Nickel is fairly strongly resistant to atmospheric corrosion, so the most likely culprit would be the Copper content. To me, this suggests that the obverse gunk cannot be removed without revealing additional surface damage. Report this Post to the Staff
