I have about 12,000 records, mainly dance/electronic music from the last 20/30 years, some of them are worth up to £500 as they are unreleased mixes on promo, that have never been played, or limited edition box sets, etc.
But outside of my collection, the most expensive record I've personaly heard about was "Frank Wilson - Do I Love You (Indeed I Do)" - release on the Motown subsidiary label 'Soul.'
Supposedly 500 demo 45s were pressed, but by that time Frank Wilson decided he would rather focus on producing and had the demos trashed.
Some how at least two known copies survived, one of which fetched £15,000 (aprox. $28,000.00).
Because of the scarcity of the original single and the high quality of the music, it has been championed as the rarest and most valuable record in history.
I think it was a big Northern Soul record.
Anyways, I have an mp3 of it, and it's ok, very upbeat, nothing special.......maybe the sorta record you might hear on a KFC advert!!!
