I had someone offer me $200 for my collection of minis. 1,000 might not sound like a lot to some people but it's 1,000 of carefully selected minis. I have enough of each monster to run an encounter with them so that's 1,000 well picked minis rather than just a random assortment.
$200. I nearly punched him in the face (he knew exactly how much they were worth as he was a collector as well). Then again, he was a major douche already and was the cause of multiple group splits and the only reason people kept playing with him was because his personal collection of DDM minis was about 6,000 (again, carefully picked). On top of that, all the ones I had were the ones he'd missed out on 'cause he started collecting late. Pfft. $200. The gall.
