You could try one of the auction houses that isn't huge. Maybe Halls?

Typical disclaimer- I've been a customer since 1977, and consigned some stuff last year. Their cut was a bit big, but the results on some of the items were much better than I could have done on Ebay. Plus some of the stuff I consigned was really slow selling... It worked out well overall.
Feel free to use my name if you contact them.
