SEALED MINT- (SS) When someone says something's "Mint condition," this is what they're talking about. The album is still sealed (SS) in its original packaging-- and has never been opened or played.
MINT- (M) This is the highest grade for records that have been played. The album is in excellent condition and shows no visible signs of wear or damage that will affect sound quality. May have some light paper scuffs or fingerprints which will not lessen audio reproduction quality.
EXCELLENT-- While not flawless, the condition is EXCELLENT, showing only minimal signs of use. Any visible blemishes should have minimal effect on play quality, though light surface noise maybe present at very quiet portions or between tracks. This is a record that should satisfy all but the most strict of collectors. There may be slight ring or cover wear, or minor writing on the cover, which is duly noted.
VERY GOOD -Vinyl may have scratches and/or other visual blemishes but should play through without skipping or repeating. Light to moderate surface noise and/or crackle may be present, however not overly distracting. Covers may have moderate ring and/or edge wear, cut-outs / hole punches, or moderate seam splits.
GOOD/ADEQUATE - sound quality is low and the cover may be in very poor shape.
