In 1996 I threw all of my GI Joe stuff away. This was every single 3 3/4 figure from the 1st generation to about 4 years later (1983-1987). I had almost every single figure, weapon (no USS Flagg...sorry) and accessory in a box and I just threw it in the garbage. I also had a few (10 or so) Transformers in the box too...although I don't remember exactly which ones.
My rationale at the time was to clear out clutter before moving. Sometimes I wonder what I could've sold them for on Ebay. Oh well, at least I kept my Star Wars figures (the true toys of Gen-X).
