I've got some original USB ASICminer Block Erupters. Haven't thought about them in a while or have any idea if they're worth anything. I think they sold for 1-2 BTC originally back in the day. I'd take a fraction of that now, unless you're one of the 1 BTC equals 1 BTC guys, then I'll happily accept the original Bitcoin price for them.

I've got some of the original Butterfly Labs FPGA miners as well, although you did not mention mining hardware that old school. Good luck with your search!
