Excellent
The record shows some signs of having been played, but there is no difference in sound quality.
The cover and packaging might have slight wear and/or creasing.
Very Good
The record has obviously been played many times,
but displays no major deterioration in sound quality,
despite noticeable surface marks and the occasional light scratch.
Normal wear and tear on the cover or extra items, without any major defects, is acceptable.
Good
The record has been played so much that the sound quality has noticeably deteriorated,
perhaps with some distortion and light scratches.
The cover and contents suffer from folding, scuffing of edges, spine splits, discoloration, etc.
Fair
The record is still just playable but has not been cared for properly and displays considerable surface noise;
it may even jump. The cover and contents will be torn, stained and/or defaced.
