NGC Ancient Grading Question
I have seen any number of ancient coins in NGC holders with the notation "brushed" but never any with the notation "cleaned". US coins with NGC details grades may note "cleaned" but I have never seen one with the notation "brushed".
The NGC Details Descriptions Glossary included the following descriptions:
BRUSHED - A coin that has been wiped with an abrasive materials.
CLEANED - A coin exhibiting abrasive or chemical cleaning.
Does anyone know why "brushed" is the favored term for NGC ancients?
