For my fellow Losties, the auction dates have been set! August 21-22 in Santa Monica. If you can't make it, you can sign up to bid online or by phone. You can also buy tickets to just go and watch or purchase the catalog. There are links to download the catalog free, as well. The info is here: Lost The Auction - Profiles in History
Although they have some big ticket items (Hurley's Camaro & a DHARMA van), it looks like most lots are starting at $200 with a few starting at $100. There are a lot of costumes and director's chairs, even a few signed scripts.
It was fun just to look through and imagine a few of those items sitting on a shelf at my house. I wish they would have put up more of the smaller props (just one DHARMA beer can ) to make it more realistic for more fans to have a chance, but most have been combined into lots of 2 & 3 items. Oh well.
Happy perusing & namaste.
