MINT M The record is as new. The cover and any inserts should be in perfect condition.
Many Dealers do not use this classification unless the record has not been played or still sealed. Spindle marks on the label would indicate the record has been played.

EXCELLENT
PLUS EX+ The record is near-mint, there is no damage or visible surface marking. Under Bright Light you may see fine lines on the record, caused by rubbing on the paper sleeve. Reserve this grade for records where you have difficulty spotting anything wrong.
The Cover and inserts are undamaged.

EXCELLENT EX The record may show some signs of having been played, possibly with light surface marks or fingerprints but there is no appreciable lessening in sound quality.
The cover and packaging might have slight wear and/or creasing.

EXCELLENT
MINUS EX- There may be fairly visible surface markings under bright light but the sound quality if the record is not adversely affected.
The Cover and inserts may have noticeable light creasing or "foxing" due to dampness but they are all present and intact.

VERY GOOD VG The record has obviously been played a lot, but displays no major deterioration in sound quality despite surface marks and some light scratches. Also Use this grading where the record has suffered perhaps one more visible scratch, but is otherwise in EX or better condition.
The cover may be creased a little and/or frayed at the opening. You should itemize any more serious damage such as tears.

Buying or selling anything in less than VG condition is not recommended, if you sell records in worse condition, expect some to get returned, even if your descriptions were honest.

GOOD G The record has been played so much that the sound quality has been affected noticeably, perhaps with some distortion and clicks due to scratches. The main place to use this classification is for picture discs, where the sound deteriorates more quickly with use.
The cover and inserts may be folded, have minor tears and/or splits at the edges, they have not been looked after.

FAIR F The record is still just playable, but has not looked after there is a lot surface noise, it may even jump.
The cover and contents will be torn, stained and/or defaced, possibly with chunks missing.
