Some folks quibble about what "new" means. Technically, if the gun was made more than one millisecond earlier, it is not "new". But in general, collectors consider a gun "new" if it is (or appears to be) unfired, except for factory test/proof firing. NIB "new in box" means new and in the original box. If papers, targets, cleaning equipment or other items are included, the seller should say so. Some sellers use the term ANIB or LNIB, meaning "as/like new in box" when the gun is new to all intents and purposes, but has, or may have been, fired.
The idea that if the gun was ever purchased it is not new won't really work with guns, as every gun, except those still in the factory, has been sold to someone. And every gun on the market, except those in a dealer's shop, is "used" even if it has never been fired. Should a "used" (previously owned) gun be resold at the "new gun" price? That depends. In some cases, it is not going to happen. No way would I sell a "like new" Luger for the 12 Marks it cost new, or a cased and unfired set of 1860 Colt Army revolvers for their 1862 retail price.
