Im looking at a large cent, by NCS and it says "burnished". I've never seen this designation on a NCS slab.
bur·nish(bûrnsh) tr.v. bur·nished, bur·nish·ing, bur·nish·es 1. To make smooth or glossy by or as if by rubbing; polish. 2. To rub with a tool that serves especially to smooth or polish.
BURNISHED is the term used when the cleaning is more aggressive and gives the coin a very brilliant but unnatural sheen. Sometimes this action is performed with some abrasive media such as ball bearings, or it may result from treatment within a rock tumbler. Never mind i found it, thanks.
