Records condition is assigned through thorough visual inspection and partial listening according to the following GRADING SYSTEM based mostly on the standard UK Record Collector magazine's grading with occasional additional sub grading "+" or "-" (covers are graded first, then records):MINT (M):
The record has never been played or played maximum a couple of times and it is in brand new condition with no visible surface marks or deterioration in sound quality. The cover and any extra items such as the lyric sheet, booklet or poster are in perfect condition.
EXCELLENT (EX):
The record shows some signs of having been played, but there is very little lessening in sound quality if at all. The cover and packaging might have very slight wear or discoloration. No cut-out holes.
VERY GOOD (VG):
The record has obviously been played many times, but displays no major deterioration in sound quality, despite noticeable surface marks and the occasional light scratch. There may be slight warps that do not affect the sound. The cover and extra items may have normal wear and tear without any major defects, more discoloration, cut-out holes, little writing, price stickers. However, there won~t be all of these problems at the same time, only two or three of them.
GOOD (G):
The record has been played so much that the sound quality has noticeably deteriorated, perhaps with some distortion and mild scratches, but it shouldn~t skip while playing. The cover and contents may suffer from folding, spine splits, greater discoloration, etc.
FAIR (F):
The record is still just playable but has not been cared for properly and displays considerable surface noise; it may even jump. The cover and contents may be torn, stained, water damaged, split on all three seams or heavily marred by writing. Still worth having until you find a better one.
POOR (P):
The record will not play properly due to great scratches, bad surface noise, jumps, etc. The cover and contents will be badly damaged or partly missing. The item is only of use as a collection-filler.
CDs either play perfectly - in which case they are in Mint condition - or they don't, in which case their value is minimal. Plastic containers for CDs are not subject to grading as they can easily be replaced if they are broken or scratched. CD card covers, digipaks, inlays and booklets are graded in the same way as record covers and sleeves.
