Robert Simon recently appeared on Forbes’ new video series Priceless, which investigates the values of some of the most unique assets owned by members of the Forbes 400 list. This episode focuses on the only manuscript by Leonardo remaining in private hands, the Codex Leicester, purchased by Bill Gates in 1994 for $30.8 million. In 1993 Robert had appraised the Codex for its previous owner, the Armand Hammer Museum of Art and Cultural Center, for $50 million (making its purchase price, in his opinion, a bargain). He and others were consulted in the video about its current value, which Forbes estimates at $130 million.
