I agree with Elizabeth. (see my earlier post) Keep in mind that vinyl album value is subjective. A collector of old Dino, Desi & Billy memorabilia may consider their 2 or 3 albums to be collectible and pay well for them but at the record store (one that deals in vinyl still) they will still only give you $1 each or less.

I had an expert check my entire remaining vinyl collection. Here's what he said... unopened (cellophane in tact), never been played vinyl has excellent collectible value. Opened, previously played, mark and scratch free (every tiny nik & smear counts) vinyl has value that depends heavily on several factors (pressing #, serial #, artist(s), release date, title of album, titles on the album, collectors buying that artist - to name a few) and setting a true dollar value is difficult unless the broker has a buyer on the hook. Things like a one-hit-wonder, though nobody knows them, may have huge value because of who or where or when it was produced or simply because there were so few produced. Demo tapes still in excellent condition from the first iteration of the Beatles (before Ringo) can sell for millions. A first European release album of Rod Stewart, opened but in perfect condition, has been quoted in the range of $10-100.

Generally, if you have old vinyl that was often played, is in scratchy condition, the jacket is ratty looking, the artist produced millions of copies worldwide, etc. Even a good price for that is $2. The Beatles"A Hard Day's Night" has no collectible value unless it was the first run release in England, is in original condition with the original cellophane unmarked (yes, a collector will know if it's been replaced) and is still in the hands of the original owner. And even then you need to find a broker to hunt down a buyer for you and pay them a commission. If youy have such an item... get the broker and sell it... you could pay off your mortgage with such items.
