Aron Meystedt, a longtime friend and domainer, managed to hold an historic auction at Heritage Auctions in Novemeber 2013. Over 2 million dollars in domains were sold during and right after the auction.
A second auction has been scheduled for mid March. They are seeking 1 and 2 word category domains, as well as generic branding names priced from $1000 to $100,000 and up. If you want to try and get some names in the auction you can email him at AronM@HA.com
Good luck to all.
