One thing that I am surprised people are not doing is selling the unappraised items... I didn't check if they are AHable, but they are definitely tradeable, not ex and not rare. Especially the ??? items you get by yourself (e.g., from the finding faults quest) seems like something you could sell for a decent amount and people would buy lots for the small chance one might not be a dud... People sorta do that for fish in the fishing quest. I guess that shows people still don't mind using them up instead for the minuscle chance at a cool new item
