The key to all of this is the concept that NOS is NOT a physical condition but rather a retail term describing the circumstance. It has nothing to do with condition. Mint or new or perfect are physical conditions.

We see this alot with NOS watches. Often times a retailer will have a demonstrator which has been in a window for 2 years and people handle it and drop it and try it on and it can have all kinds of scratches and nicks but it's still NOS because it has never been sold before.
