"Altered Surface", The need for a more comprehensive definition?
in Ask NGC/NCS
Posted
It is true that coins that have been improperly cleaned, whizzed, polished, and the like have altered surfaces. A coin in an NCS holder that has had a specific treatment of whizzing, cleaning, polishing, or the like will have that specific problem mentioned. Coins that are in NCS holders with "altered surfaces" most often are coins that have had their surfaces specifically altered in a way to make them appear to be something they are not. Most often this is a treatment to either the devices or fields to give the appearance of a cameo proof.
