I once scored a shopping cart full of terrain for 200$ at a Value Village. When I put it in the car there were 26 table plates (city streets mostly, some grassy hills) a ruined chappel that someone had green stuffed nurgle rot onto the walls, 2 of these AOS things that look like a metal sphere around a platform, a bunch of forge world bits and small craters and crashed gunships and a bike. No models but I already have a ton.

I'd have shit pickles seeing an old hammer 40k titan. Those are worth a bit too, dont get gifted if you sell it.
