Still, my favorite is an eBay listing for two USED oil-paper capacitors like were used in tube circuitry in the 1960's for $150 starting bid. The big "selling point" was "Les Paul", so maybe they were from a guitar amp. They had about 1/4" leads left on them, these were the black molded plastic "bumble bee" caps that were fairly notorious for going bad. I can't imagine that somebody actually bought them.
I have this listing on my wall at work.
I do still see somebody selling a partial reel of 1206 resistors on eBay for $250+, wonder when they might get a clue as to the real value of such parts.
