M= Mint VG = Very Good G = Good
M = Excellent, flawless
M- = Slightly less than perfect.
VG++ = Not quite good enough to be "M-" grade. Some scuffs, possibly a few light scratches which shouldn't affect play.
VG+ = Has a few more minor scratches and scuffs, but definitely well taken care of.
VG = Has too many scratches and scuffs to be called "VG+", but still in fairly nice condition.
VG- = Not great condition, quite a bit of wear.
G = Excessive wear. Probably plays through but very noisy.
POOR = Just what it says - no guarantee.
I try to grade conservatively
