NM (Near Mint):

Near perfect. No obvious signs of use, it may have been played - but it has been handled very carefully.

Insert/Inlay/Booklet/Sleeve/Digipak: Near Perfect. No obvious wear, it may have only the slightest of marks from handling.

VG+ (Very Good Plus):

A few minor scuffs/scratches. This has been played, but handled with good care - and certainly not abused.

Insert/Inlay/Booklet/Sleeve/Digipak: Slight wear, marks, indentations, it may possibly have a cut-out hole (or similar).

VG (Very Good):

Quite a few light scuffs/scratches, or several more-pronounced scratches. This has obviously been played, but not handled as carefully as a VG+.

Insert/Inlay/Booklet/Sleeve/Digipak: More wear, marks, indentations than a VG+. May have slight fading, a small tear/rip, or some writing.

Good:

There are a lot of scuffs/scratches. However it will still play through without problems. This has not been handled with much care at all.

Insert/Inlay/Booklet/Sleeve/Digipak: Well worn, marked, more obvious indentations, fading, writing, than a VG - possibly a more significant tear/rip.
