The item I was most excited about came from the collection of Michael and Denise Okuda. It's a "doorbell" that was used in the set for the home of T'Pol's mother in the Star Trek: Enterprise episode "Home." I love how the design reflects the shape of the Vulcan gong that was introduced in "Amok Time." The whole piece is just really pleasing to look at. It sold for $900!
Another unique item that sold for $100 was a foam core pre-production model of the Vulcan ships seen in Star Trek: The Next Generation "Unification." I've previously written about Rick Sternbach's design and actual model of the ship here.
