Can you guess the most valuable corkscrew?

A few weeks ago, we hosted a professional happy hour at our office which included tapas and plenty of wine, but also included a limited viewing of the corkscrew collection. At our office we have four framed corkscrew displays mounted on the walls as well as a couple extras that I brought in for the occasion. It didn't take long for the viewing to be turned into a fun game of guess the most valuable corkscrew. We asked roughly 40-50 people to guess the most valuable corkscrew out of the 14 below and not a single person guessed it. The most valuable (by a very high margin) is the one located in the center of the second picture with the single lever (top left of the first picture). The majority guessed the scrimshaw George Washington carved piece followed by the intricately carved dragon with Sterling silver tail followed by the skeptical few who thought it was the Weir's compound double lever. Almost every piece was guessed except for the most valuable which I thought was pretty interesting.
