OK, I'm askin' for trouble, but I have always used "Mint" to describe a brand-new chip. Preferably out of the box, although such is not always possible to obtain when buying from the tables or a cashier's till.

And near-mint when said chip has been sitting beside some Girl Scout Cookies.

There is somewhere a chart showing different "grades" of chips and includes Average, Good, Very Good, Little Girl With A Curl On Her Forehead (kidding on that grade), Near-Mint, and the aforementioned Mint. Maybe I've been going about this all wrong for the past 7 years?

And there is also a Mint Cigar chip. Try lighting one of those up, Cigarman.
