The record Collector's grading system seems to be the standard in the UK, but is a little hazy...I have expanded it a little for the purposes of my ads, but of course, that then makes it my definitions. In reality it is of course completely subjective....if you are looking at fleabay, I would suggest first & foremost look for a seller (of vinyl!) with good feedback:
All items are visually graded using Record Collector magazine grading system (as per the small print).
THE ITALIC CAPITALS EXPLAIN HOW I TRANSLATE THAT GRADING SYSTEM INTO THE REAL WORLD!
Mint: Record is in brand new condition with no surface marks or deterioration in sound quality. Cover in perfect condition.
I VERY RARELY GRADE AS MINT!! 'NEAR MINT' MEANS UNMARKED VINYL, NO NOTICEABLE SPINDLE MARKS ON THE LABEL, LOOKS UNPLAYED.
Excellent: Record shows some signs of having been played, but there is very little lessening in sound quality. Cover & packaging may have slight wear and/or creasing.
I GRADE RECORDS AS EXCELLENT IF THEY HAVE NO NOTICEABLE MARKS ON THE VINYL & MINIMAL SPINDLE MARKS. A SINGLE SIGNIFICANT MARK WILL DOWNGRADE IT TO A 'VERY GOOD'.
Very Good: Record has obviously been played many times, but displays no major deterioration in sound quality, despite noticeable surface marks and the occasional light scratch. Normal wear and tear on the cover or extra items, without any major defects, is acceptable.
I GRADE RECORDS AS VERY GOOD IF THEY HAVE MINOR SCUFFS, MAYBE SOME VERY LIGHT NEEDLE MARKS - LOOKS LIKE IT HAS BEEN PLAYED A FEW TIMES, BUT HAS NO MAJOR FLAWS. THERE MAY BE AN OCCASIONAL REPETITIVE CLICK FROM A MARK OVER A SMALL SEGMENT OF THE RECORD, BUT NOTHING SERIOUS ENOUGH TO DETRACT FROM OVERALL LISTENING TO THE RECORD. RECORDS THAT ARE BORDERLINE BETWEEN EXCELLENT & VERY GOOD ARE GRADED 'VERY GOOD+'
Good: Record has been played so much that the sound quality has noticeably deteriorated, perhaps with some distortion & mild scratches. Cover and contents suffer from folding, scuffing, spine splits, discolouration etc.
I GRADE RECORDS AS GOOD IF THEY HAVE HEAVIER SCUFFS, AND/OR SOME LIGHT SCRATCHES OR NEEDLE MARKS - LOOKS LIKE IT HAS BEEN PLAYED MANY TIMES. SOME BACKGROUND NOISE, DISTORTION, RECURRING REPETITIVE TICS ETC BUT NOT UNLISTENABLE.
Fair: The record is still just playable but has not been cared for properly and displays considerable surface noise: it may even jump. Cover will be torn, stained and/or defaced.
IT IS RARE I WILL SELL THESE - ONLY IF REALLY COLLECTABLE. THE RECORD MAY JUMP, MAY BE BADLY SCUFFED & SCRATCHED.
Poor: The record will not play properly due to scratches, bad surface noise etc. Cover will be badly damaged or partly missing.
NOT WORTH SELLING!!
Good luck..
