How do I value my collection?

[JimK]

I have about 100 cases of interesting wines -- mostly Boardeaux and California, lots of Dehlinger, and good years. I've avoided drinking a LOT of good stuff. Now I want to sell most. How do I locate someone who could appraise my collection, and perhaps point me to a way to dispose of it? Obviously if it isn't an independent appraisal, I'd want several unrelated bidders. Help/advice sought. thanks!
