Gun shows in this area (Spokane) have 9mm and 40 brass for a nickel a piece. This is unsorted, untumbled, and non-decapped range brass.
I tried to trade some 40 S&W at the last gun show here. I had resized and tumbled it enough that it looked almost new. I though this would make it more desirable, but none of the dealers wanted it, as they said once it was decapped, they couldn't sell it as "once fired", which I don't really get, as there are non-plated primers available.
