Spots, Spotting

Spots, Spotting.  Any of a number of small blotches of toning, tarnish or corrosion appearing on the surface of a numismatic or medallic item. Water spots are particularly unattractive, as well as sulfur spots (formerly called "carbon spots"). Removal of spots, stains, blotches is called spotting out and is part of refinishing.
