NGC Details Grading
Quote:
TOOLED refers to either the smoothing of a coin's fields to remove scratches, corrosion and other forms of damage or to the restoration of lost details through use of a graver or knife. When a single side of the coin is affected, the terms OBV TOOLED and REV TOOLED are used.
SMOOTHING is akin to Tooling, but it is used when the exact means of achieving the described effect is unknown.
