Christie's New York will be auctioning off Watson's 1962 medal Dec. 4 and projects it will bring a bid of between $2.5 million to $3.5 million. The medal was awarded for Watson's groundbreaking discovery, alongside Dr. Francis Crick and Maurice Wilkins, of the structure of DNA: the double helix.
A Nobel Prize medal has never been offered for sale by a living recipient. The family of Dr. Crick, who died in 2004, sold his medal at auction in 2013 for $2.27 million.
