Mister Kairu, he was worried that the thread would degenerate into what would be thought as a simple sales offer instead of the research into venues he intended. It hasn't.

Jon, this one deserves a reputable online/meatspace auction. I strongly believe the increased exposure to a specialized audience would compensate for any increased cost of business. Consider consigning to one of the event-associated "Signature" auctions. While waiting, maybe float it on the market with one or two of the market-makers in the category who would have regulars interested in such a coin.
