Bo, I swear, I'm going to find a way to get to your house so I can smuggle some of those records out.
Man, the rarest one I've got is a mono copy of Sgt. Pepper's. I paid $15 for it, but it's worth about $100, even though it's not in very good shape. I saw another copy at the local record shop selling for $600 because it was in really nice shape. Even better, I found a second copy at a record sale, just the disc, though, and bought it for $3. I'd guess it's worth about $50 on its own.
I also have an authentic copy of Introducing The Beatles that my aunt gave me. Most counterfeited record of all time, of all time, with only 10% being authentic copies. It's worth about $40.
By the way, QS, your typo reminds me, there was a piece of Beatles merchandise, a pin that said something like "Official Beattles Fan". If you can find one of those, they're worth a few bucks!
