Original high-grade VeeJay copy of "Introducing the Beatles". Don't remember what I paid, bc I eventually got a full refund. The idiot who sold it to me mailed it 3000 miles packaged between two pieces of corrugated cardboard. Worse, he'd cut those pieces from a cardboard box and positioned the box's crease right in the middle of the cover (LP inside the cover, of course). As you've probably guessed, the pkg bent in the middle during shipping and the album arrived in two pieces. And the guy didn't buy insurance.
The worst part, though, is that the seller guy refused to give me a refund, and it took weeks of haggling with eBay to force the guy to give me my dough back. eBay is not Amazon when it comes to buyer protection.
Echoing another poster, the two albums I SOLD for the most were a Second State Butcher Block and an original mono UK Trak copy of "Are You Experienced" (bought when I was a kid in 1967 off the shelf from a record store in Bermuda -- and played only a few times b/c, frankly the sound was awful to the point of being nearly unlistenable). Both went for $5-600, which most people would find jaw-dropping, but here, makes me a piker.
