Standard grading scale
Mint (M) – Perfect. Unplayed/unopened.
Near Mint (NM or M-) – Almost perfect. No visible marks.
Excellent (EX or VG++) – Very light signs, faint marks.
Very Good Plus (VG+) – Light scuffs/hairlines, minor noise.
Very Good (VG) – Noticeable surface marks, some noise.
Good Plus (G+) – Heavy wear and audible noise, but it plays through.
Good (G) – Very heavy wear, noise throughout, but still playable.
Fair / Poor (F/P) – Barely or not playable; sleeve heavily worn.
Sleipnir assigns NM, VG+, VG, G+ and G. Mint is for sealed copies it cannot verify, and Excellent, Fair and Poor belong to other sellers’ vocabulary — you will meet them on Discogs, but Sleipnir will not hand them out.
