Ed HansI don't trade much anymore, but my best by far was in the early 90's. I traded a 1989 Upper Deck factory set to a local dealer, for an E97 Meyers. The dealer threw in $35 to even up the trade. I sent the E97 to PSA. It came back a 7.
As far as bad ones, I'd have to go back to the early 70's, when I would routinely trade major stars (in multiples, if necessary) for commons I needed to complete series. That was actually fairly common practice in those days.
