I guess I'm less thinking about financial leavings and more artifacts and interesting books. Certainly, Eb has his journals going back to the original Merlin (per whatever book that was). We have The Blackstaff, Mother Winter's walking stick. I think many here believe Dresden will return it to her. I just wonder what ends up in the junk pile and what Dresden keeps as an heirloom and whatnot like that. I know, hard to guess without knowing more about other wizards and their collections of goodies, but I thought it might be curious to think about.
Maybe Jim will do a short story of how Eb came to be in possession of the Blackstaff or something else that hasn't revealed itself. Maybe something necessary for the BAT.
