The following sentence may sound like the logline for an as-yet unmade National Treasure 3, but it's very much real: A large group of crypto maximalists is banding together in an effort to obtain the actual U.S. Constitution.

From a report: Unlike the antagonists in the previous Nicolas Cage movies, this crew might actually succeed. Or kind of, anyway. On Thursday, November 18, Sotheby's is auctioning off "an exceptionally rare and extraordinarily historic" first printing of the U.S. Constitution. Only thirteen copies remain, besides the one located in Washington D.C.'s National Archives museum, from the original printing of 500 that the founders issued for submission to the Continental Congress. It's the first time in 30 years that this one has become available for purchase, following the 1997 death of its last winner, New York real estate developer S. Howard Goldman.

It's expected to fetch between $15 million and $20 million in the auction -- unless, of course, it instead fetches the equivalent in Ethereum.
