Let's say you have a gold gilt over silver coin. The coin is blemish free but over the years the gold gilt disappeared. I have one such coin - actually, a token. It's from 1932 and it's not blemish free but it's in great condition. However, it's supposed to have gold gilt, but it's completely gone somehow. I guess another example is if the zinc layer on a 1943 steel cent somehow wore off and the steel core is remaining. Maybe that's a bad example. A gold gilt coin is a better example. Any thoughts? Thanks in advance!
It's not perfect but it sparked my curiosity for the general grading criteria for coins with no gold gilt but in "MS" condition.
