I sold all my 2e stuff in about 1998 or so. all the class and racial handbooks, skills and powers, spells and magic, combat and tactics, all my planescape box sets, all my fr box sets, I have given away more 3e stuff then i would care to recall.
I am so not going to think about this anymore. yes it sucks. I really wish i could flip through the bards handbook right now, I want to play a blade again, now that was a cool bard.
as for my MtG cards, sold those well before that. as in before there were multiple series. Kinda wish i had kept a few of those.
