When listing records to sell, wether that's LP's or 45's or even 78's, condition of  the vinyl is the most important factor to a potential buyer. Online record buyers are generally not collecters but listeners and lovers of great sounding music.They care about covers to the degree that they are sound and presentable but mainly they want to know if a record is scratch free, warp free, and dirt free. They may have limited knowledge of industry grading standards but they do understand and respond favorably to terms such as like new, near mint, mint, no surface marks, high gloss scratch-free surface, etc..., visual terms with universal meanings. Many sellers rate vinyl according to rating systems they themseves have conceived, unfortunatly this is rather arbitrary to a buyer. Try to use industry rating standards such as Goldmine's but give buyer's a visual recommendation also. Scratch-free is much less subjective to the non-collecter than a rating of say VG-. If records have been listened to, audio recommendations of pop-free and low surface noise are comforting descriptions to a buyer about to drop hard earned cash on a purchase. One final note, when shipping to the south during the summer months remember that warping can occur while records are sitting in wharehouses and in delivery trucks so pack them tight with reenforcement if possible. And it's always a good idea to wrap them in some type of waterproofing, even just a shopping bag in the unlikely event that a package is dropped off to an uncovered area. Happy selling!
