Most do a visual and describe if they see scuffs, scratches or warping. Look at it carefully in good light. The best way to see a warp is to put on turntable but you can see it without turntable if it's really bad. Describe any defects you see. Also look at the jacket for ring wear, splits, writing, etc. Some will play grade before selling and describe sound quality. More time consuming but buyers like this if they are paying top dollar for somethng very collectible. Photo graph front and back of cover, record front and back and any special features, such as booklet etc.
