I use the following for the jackets:

NM: Near perfect with no visible signs of handling

EX: Looks almost perfect, but may have a couple of imperfections after closer inspection. May have a small saw cut, punch hole or a cut corner.

VG+: Typically has a few imperfections such as slight creasing, slight ring wear, or slight wear from storage. Very light seam wear or splits in the spine. May have saw cut, punch hole or corner cut.

VG: More pronounced wear than a VG+. Perhaps several scuffs, scratches on the cover and more prominent spine wear and/or ring wear. May include writing, light staining, or minor damage.  This may also have a saw cut, punch hole, or cut.

VG-: Similar to VG, has heavier wear such as  heavy spine splitting or heavy staining, scuffing, etc. Might have saw cut, punch hole, or corner cut.

G: Heavy wear, marks, scratches, staining, spine damage.
