What was the most expensive record that you ever bought ?

The only thing that's sucks is you spend big money on an unopened lp and one day you sell it for even bigger money.To find out it's a different copy and not the one on the cover...  So I don't buy sealed copies ,buyer  beware there is fraud everywhere......

Sealed vinyl might be defective, it's not always fraud. I don't buy them above, say, $20 either unless I can return it.

Thorens 125th Anniversary LP. I paid $350 for a mint copy.

However, I sold an LP for $2k once. 

I have not bought an LP since 1982, and I don't remember what they cost back then, but I know that I wasn't going out of my way to buy quality pressings.

However, within the last few years, I did pay a seller $100 for a JVC XRCD red book of Linda Ronstadt's Greatest Hits .  (It was Different Drum that I really wanted.)  The seller was raving about the sonic quality, but I didn't think it was that great.  IMO, the DCC red book of Linda Ronstadt's Greatest Hits Volume 2 sounds way better as does the MFSL red book of Simple Dreams, and I could probably go on and on about CDs I paid a lot less for that sound a lot better.

Anyway, a while back ago I was taking it out of its jewel case and it snapped in half.
