One of the members here recently purchased a gun from an auction. A nickel 29-2 that was advertised as "unfired!!". When he got it there were burn rings present. When he talked to them about it, they said that they only meant it was "mint". Well, I always thought that mint was as it came from the factory. Untouched. Mint. Once you fire it, it's no longer mint. Thus all mint guns are unfired but not all unfired guns are mint. By the way, this was not the factory test firing. This gun was shot. Maybe just a cylinder full, but it was shot. What do you guys think mint means?
