Like "Fair", we rarely list records in this condition, as they represent the extreme low end of spectrum. These records typically have multiple serious problems, and we offer them as "relics" or "objects" only — for those who want to at least have a copy of a record, even if it is not really worthy of play, perhaps for the cover alone. For these records, we will describe the extent of the condition in the comments.
If something is noteworthy, we try to note it in the comments — especially if it is an oddity that is the only wrong thing about the record. This might include, but isn't limited to, warped records, tracks that skip, cover damage or wear as noted above, or strictly cosmetic flaws.
