I was getting nearly 300 a page for average content Butler Sable this auction. I have been doing well with them for a while, its one of those niche things that a few guys go after.
If you don't live in NYC or someplace HA has offices, you can always just meet one of their rep's at a convention and do a hand off there. Part of the reason I do the NJ art show 2x a year, besides seeing all the art and making some purchases, is that I can just hand my material off (after an inventory session) at the end of the show. It really saves a lot of money, especially if you have like 200-300 pieces.
