Close to $2000 of assorted GW, Target, and Grenadier minis and rulebooks, with much L5R 2e material and the odd RPG supplement for $300 from a game shop going out of business. Me and another guy basically bought their entire remaining game stock for peanuts.
I just remembered that back in 1998-ish, I answered a For Sale ad in the Topeka Capital Journal for "magic cards and some books - $75 takes all" -- "some books" turned out to be five milk crates full of AD&D modules (all the modules ever published for AD&D 1e, actually) and rulebooks (all the hardcover AD&D 1e rule books, plus some early 2e stuff), a suitcase full of early Chaosium material (Elfquest box sets, anybody?) and a cardboard box of miscellaneous fantasy supplements from Judge's Guild, FGU, etc.
I can't believe I forgot about this. Apparently the books were the property of some guy's deadbeat son, who stuck dad with five months worth of unpaid bills and then got incarcerated. Most of the modules can still be found at Dean's Used Books on Kansas Avenue in Topeka, I think. I single-handedly created their module stock back then (I didn't use modules at the time, so I sold them all to Dean's with the exception of the Sentinel series and the original Ravenloft module).
