I would add:

-Most if not all Avalon Hill strategy games especially if CIB
-The residents Bad Day on the Midway and Freakshow (value on these flctuate)
-Relentless: Twinsen's Odyssey
-Riana Rouge (one of the few comercially released AO games)
-Queen: The Eye

I'm trying to stick to more commercially available games that have not been mentioned although some of the older Avalon Hill games are probably not too common. These games tend to have decent value regardless of just in a jewel as well. I'll add more as they come to mind...
