Mint Record is unplayed, in perfect condition and possibly sealed
Near Mint Record is as new (perfect) but has been played
Very Good++ Record has very minor blemish but no major marks and/or sleeve has minor blemish but no splits or tears
Very Good+ Record has some light surface marks and/or sleeve has minor blemish
Good Record has more light marks bu little surface noise and/or sleeve has split, tear or minor damage
I normally grade records by sight rather than by playing them.
