The biggest trade I ever made was in jr. high. A friend and I had a huge deal under way, hundreds of cards, with the closer being a stack of 1960s commons for a 1958 Bell Gino Cimoli SP. Wish I still had that one. I have no idea what happened to it.
The most complicated trade I ever did was one boxing trade at a national a few years ago. It took us four hours to work it all out. Basically, we were swapping cards and related items that really had no market prices so we had to deal the old-fashioned way, by comparing the quality of the athletes and general knowledge of the issues and working it without the crutch of price guides to aid us. I felt like I'd given birth at the end...to an accountant! Some of the items I picked up:
1904 Battling Nelson card:
1935 Joe Louis premium:
Joe Louis Rum label:
