From “The Scarlet Plague” by Jack London:
“2012,” he shrilled, and then fell to cackling grotesquely. “That was the year Morgan the Fifth was appointed President of the United States by the Board of Magnates. It must have been one of the last coins minted, for the Scarlet Death came in 2013. Lord! Lord!?think of it! Sixty years ago, and I am the only person alive to-day that lived in those times. Where did you find it, Edwin?” The boy, who had been regarding him with the tolerant curiousness one accords to the prattlings of the feeble-minded, answered promptly.
