SS
(STILL SEALED) Sealed at factory and never opened. Disc is assumed to be undamaged and mint, but this cannot be proven until the album is actually opened and the disc examined.

M
(MINT) Perfection, no flaws, defects, marks or otherwise indications of being handled or played. Any scuffs, hairline scratches or other marks disqualify discs from this category.

NM
(MINT MINUS) The vinyl is virtually flawless, bright and shiny. A very minor, barely visible scuff or two may be permitted, but no scratches. The disc should play with no audible noise. The label is bright, clean and unmarked.

VG++
(VERY GOOD ++) Disc plays near perfectly, but may have minor paper scuffs that do not interfere with the sound quality. There can possibly be a hairline scratch or two but nothing that is obvious or affects play. Vinyl is bright and shiny; label is clean and unmarked.

VG+
(VERY GOOD PLUS) Some visible surface wear, very minor scratches and scuffs, but minimal impact on the sound quality. Vinyl will still have good luster; labels may have minor imperfections (small labels or initials, etc.) but otherwise clean.

VG
(VERY GOOD) Vinyl will have noticeable scratches or scuffs that cause minor surface noise, but do not overpower the music. There will be no skips. Vinyl may appear somewhat dull and grayish. Labels may have small tears, tape marks, larger writing, etc. but still easily legible. 

G
(GOOD) Well-played, dull, grayish vinyl with deeper scratches and wear causing distracting surface noise (hisses, pops, cracks and other nasties). The record will still play through without any skips. Labels may be significantly defaced or damaged.
