Vinyl
A record in Good Plus or Good condition can be played through without skipping. But it will have significant surface noise, scratches, and visible groove wear. While the record will be playable without skipping, noticeable surface noise and “ticks” will almost certainly accompany the playback. A cover or sleeve will have seam splits, especially at the bottom or on the spine. Tape, writing, ring wear, or other defects will be present.
CD
There are a lot of scuffs/scratches. However it will still play through without problems. This has not been handled with much care at all.
Insert/Inlay/Booklet/Sleeve/Digipak: Well worn, marked, more obvious indentations, fading, writing, than a VG – possibly a more significant tear/rip.
Standard Jewel Cases: These are not graded as they are replaceable.
Cassette
Tape will have heavy wear on shell. Felt stopper may be missing. Tape may have minor creasing, but not broken. Must play through, may have heavier degradation that will overpower music. Sleeve will be well worn, marked, and contain obvious indentations, fading, and/or writing, more so than a VG grade – possibly a more significant tear/rip.
Generic
Within the context of grading items, the term “generic” refers to a type of sleeve that is not specific to the release. A generic sleeve is either a plain sleeve or a company sleeve with standard company artwork. A sleeve that is graded as “generic” needs no further grading, as a generic sleeve generally adds little value to the item and can be easily replaced.
