The grading of paper accessories:
LP and EP covers and Picture Sleeves and even Labels
follow the same general lines with respect to it's visual qualities. Flaws
such as tears, splits or marks should be noted.
Grades one
through four have little or no value, with the possible exception of it
being extremely rare or in high demand. Grade five is usually used as a
filler in a collection until a better copy is located. With the exception
of rarities, these too have little value.
Warps lower
value from slightly for a slight storage warp, to greatly for the wavy
type. Unplayable warps are generally considered valueless.
Grading is
in the eye of the beholder, Only true mint objects are unmistakable, all
other grades are subject to misinterpretations and mistakes.
