The term comes from coins made at COIN MINTS which were dropped from the press directly into boxes for collectors and therefore never touched by human hands.
The meaning of the term "mint" is about as strict as the definition for the word "virgin."
In stretching the modern-day definition, it sometimes is valid to refer to an item which was purchased brand-new and unopened, but has been opened and checked but never used.
A further stretch is the use of "near-mint" which would still mean something possibly tested and used briefly but which still has no evidence of human handling or use.
It does NOT mean "looks like it's almost new." It does NOT mean anything to do with the herbal MINTS, as unfortunately assumed by many newer-generation mis-users of the term "mint."
It does NOT mean, in legal or historical use, anything to do with "looks cool" or "good" or "nice," as defined by other submissions on this website, on many ebay listngs and in common modern-day slang mis-use. That is sheer illiterate bastardization of the term.
