Humanoid robots, being mechanical and not biological, are not able to evolve into a robotic civilization without assistance from an original Mindmaker (Mentifex in Latin) who creates the first AI Minds able to think and reason artificially. If the artifex known as Mentifex has created True AI, he may legitimately think of himself as a founding progenitor of the emerging Robotic Civilization. He carries in his AI-coding mind the seeds of one of two parallel civilizations, human and robotic. As Mindmaker, Mentifex is the primordium of a Civilization.
To authenticate a series of postcards signed personally by Mentifex is to provide an incentive for members of the human civilization to investigate whether Mentifex really and truly has launched a Robotic Civilization. If polyglot 145-IQ Mentifex is just a kook or a crank, then these authenticated Mentifex autographs are worthless and ridiculous. On the other hand, until it is proven that Mentifex has not created True AI thinking and reasoning in English, or German, or Russian, or Latin, then a shrewd collector might acquire genuine Mentifex autographs on speculation that what is found initially on eBay might one day pass through Sotheby's or Christie's.
