As a buyer (and seller) of vintage records I find it frustrating when I check out a listing to find that it has minimal information about the item. There have been too many times where I have searched for a record only to find that crucial info is missing. To be sure, most of the record dealers on eBay know what information to list. I'm talking about the novice seller who has a few old records he/she wants to get rid of. Here are the things I look for (and provide) when listing albums:

• Pictures. I look for the front and back covers, as well as the label. This gives the buyer a lot of information on which release he or she is bidding on (earlier pressings will look different from later ones). Pictures also let the buyer know if the actual condition of the item matches the description. Photograph any extras, including posters, inserts, original inner sleeves, and any other stuff that came with the record.
• Songs. This is crucial. The songs on an album tell you a lot about which pressing it is. Songs are added or deleted depending on record company whims. Occasionally, a record will be released, only to be recalled with a different song lineup. Knowing the songs tells the buyer whether the LP is worth $5.00 or $500.00 (or more).
• Record Company and Catalog Number. This is helpful in distinguishing whether the record is mono or stereo and which pressing it is.
• Condition. Obviously, the is the most important piece of information you can provide. It's best to use an established grading system rather than using terms like "excellect" or "pretty good." Most sellers use the Goldmine standard (see below). It's really helpful if you grade the cover separately. In grading, it's best if you clean and play the record thoroughly. This lets you truly know the record's condition. I have played LPs that looked great but turned out to be warped or worse. If you can't play them, at least clean them and look at them in at an angle in a bright light (sunlight is best).

That's it. Include this info, and you'll have a much better chance of selling that record for more than you expected. Vinyl Rating Guide
Sealed Copy/Mint: Brand new and unused.
Near Mint: Record has very little wear and no scratches.
VG+: A Very Good Plus record will show some signs that it was played and otherwise handled by a previous owner who took good care of it. Record surfaces may show some signs of wear and may have slight scuffs or very light scratches that don't affect one's listening experiences. Slight warps that do not affect the sound are "OK".
VG: Surface noise will be evident upon playing, especially in soft passages and during a song's intro and fade, but will not overpower the music otherwise. Groove wear will start to be noticeable, as with light scratches (deep enough to feel with a fingernail) that will affect the sound.
Good: Can be put onto a turntable and will play through without skipping. But it will have significant surface noise and scratches and visible groove wear
Fair: The record is cracked, badly warped, and won't play through without skipping or repeating.

Cover Rating Guide
Sealed Copy/Mint: Brand new and unused.
Near Mint: An LP cover should have no creases, folds, seam splits or other noticeable similar defects. No cut-out holes, either.
VG+:An LP cover may have slight signs of wear also and may be marred by a cut-out hole, indentation or corner indicating it was taken out of print and sold at a discount.
VG: Cover may be marred by writing, or have tape or stickers (or their residue) attached.
Good: A cover or sleeve will have seam splits, especially at the bottom or on the spine. Tape, writing, ring wear or other defects will start to overwhelm the object.
Fair: The LP cover is water damaged, split on all three seams or heavily marred by wear and writing. Cover barely keeps the LP inside it.
