I don't remember who, but i traded them a Topps US175 Trout RC for (I think) a Brian McCann auto. At the time a fair deal, but that Trout RC tripled (maybe even Quadrupled?) in value over that time while McCann ... he got traded from the Yankees 
so a great deal for him ... for me? turned out to be only 'okay' ... if he wasn't traded I'd be so much happier.
My best deal in cards was mentioned on another thread. 10 Bo Jackson RCs for a Rickey Henderson RC. Not as amazing as getting a Michael Jordan RC like the OP, but it was pretty decent, looking back.
My best trade ever ... was probably in Comicbooks. But I wont bore you with the details.

I guess if I saved used tinfoil and used tea bags instead of old comic books and old baseball cards, the difference between a crazed hoarder and a savvy collector is in that inherent value.
