I will use this system for Vinyl grading based on the Goldmine standard and is as follows


"SS" Still Sealed
-for the collector that demands nothing but perfection


"M" Mint to "NM"Near Mint
-in factory freash condition,like new in near perfect, or unplayed condition


EX+
-close to like new with only superficial signs of use that don't affect play


VG++
-a used,reasonable copy with great sound & the slightest background sound.
Shows slight minimal signs of wear

VG+
-There will be obvious signs of wear and the possibility a few skuffs and/or light surface noise between tracks or during quiet spots, but still quite nice

VG
-significant wear and marks and usually quite noticeable surface noise,still plays great

Good or Poor
-Will have multiples scuffs or scratches that may be associated with background noise/clicks/pops or even skip if noted
