Not being a member of the Steve Hoffman forum, and apparently because of this, I'm not entitled to a Search function, would you be so kind as to post the forum link? Thanks.
Hoffman forum CD grading:
Mint (M): Looks like the wrapper just came off. No marks of any kind anywhere on the complete package.
Mint minus (M-): Very near perfect playing surface and artwork. When held at an angle under extreme lighting you can see perhaps 1 or 2 very light scratches or pin dots.
Excellent (Exc.):CDs in this condition look used, but like they were taken good care of. Only a few very light scuffs can be seen when the disc is held at an angle to the light. The booklet and inserts are present and have only a few very minor flaws such as a slight bend or light fingerprints
Very Good plus (VG+): No more than 10 very light to light scratches between 1/8" and 2". Artwork has case dents or a crease. Plays perfectly.
Very Good (VG) : CDs in this condition are more for listening to than collecting. The disc is heavily scratched but can be played through without skipping. The booklet and inserts are present but heavily worn, and may include heavy fingerprints, bent corners, smudges, creases, case dimple marks, and writing.
Poor (P): Car CD or Cat toy
