How about this sellers grading scale (
http://www.ebay.com/itm/280959243814?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 ) :
MINT (M)
Still factory sealed. Absolutely perfect in every way. Certainly never been played.
MINT- (M-)
Nearly perfect in every way. May have been played once or twice.
NEAR MINT+ (NM+)
A nearly perfect record. The record should show no obvious signs of wear.
NEAR MINT (NM)
Will show some signs that it was played and otherwise handled by a previous owner who took good care of it.
NEAR MINT- (NM-)
Will show some signs that it was played and otherwise handled by a previous owner who took good care of it, but will have some light scuffs or scratches that do not affect play, may have one or two light pops or clicks.
VERY GOOD+ (VG+)
Surface noise will be evident upon playing...but will not overpower the music. Groove wear will start to be noticeable, as will light scratches
VERY GOOD / VERY GOOD- (VG / VG-)
Can be put onto a turntable and will play may have some skipping. Significant surface noise, scratches and visible groove wear.
(WE DON’T SELL ANY RECORDS WITH THIS GRADING UNLESS VERY RARE & COLLECTIBLE)
So "very good" is so bad that he usually doesn't offer it for sale
