Gradation of quality of vinyl records:
SS (Still Sealed): sealed LP
M (Mint): a new, but printed record. The record was not played or played several times.
NM (Near Mint): almost a new record. The record was played more than 2-3 times, but it did not affect her condition. The "natural" minor "superficial rustle" in the pauses for example (rare, but occurs even on new records). Externally, either perfect or minor scuffs from the inner envelope, but they are hardly audible. The envelope may have minor breaks or defects that do not spoil its appearance.
EX (Excellent): the disc was in use, but is in excellent condition. There may be minor, not much audible extraneous sounds, such as rustle, crackling or "small sand", it does not spoil the overall "sound picture". How heard such defects, also depends on the condition and type of needle. Surface scratches and scuffs are allowed on vinyl. On envelope are permitted wear in the form of minor circles (characteristically for American braces), small defects on the corners or bends.
VG (Very good): the record was in active use, but in General - a satisfactory condition. Vinyl has scratches and scrapes, while listening to emits a soft, clicks; can (rarely) episodic jumps (jumps). As a rule, there is a "sand" medium audibility.
The envelope is well preserved, but has noticeable scuffs, the corners can be bent, the seams are scuffed, there may be cracks on the seams, the spine and the perimeter of the envelope, partial divergences of the seams, the round contour of the plate may have obvious frayed outlines. However, in General, the image on the envelope is clearly visible
Good: record, with a strong desire, you can still listen, but the sound quality is very low, frequent jumps. On vinyl significant scuffs and scratches, greatly spoiling the sound.
