Mint (M) ? Absolutely perfect in every way. Never been played and usually sealed.

Near Mint (NM) ? The record has been on a shelf between other records. The vinyl looks glossy and clearly has only been played a few times. There are no marks on the vinyl and the whole package is complete.

Excellent (E) ? Same but I'd tolerate very light marks where the vinyl has been in and out of the inner sleeve a few times, or tiny signs of use generally.

Very Good Plus (VG+) ? A few further faults are acceptable, but nothing that really compromises the record visually or audibly. A little rub, light inaudible marks, a little background crackle.
