The 23-carat gold medal awarded to the late Alan Lloyd Hodgkin went under the hammer in Los Angles late yesterday and was purchased by an unidentified private collector.
Bidding for the medal sold by Nate D Sanders Auctions began at USD 450,000 dollars and shot up to USD 795,614 as four people vied for the prize, the auction house said.
The medal features the relief portrait of Alfred Nobel on its front and the laureate's name and the year it was given on the back.
Since early 2014, about 10 Nobel medals have gone up for auction as laureates or their families cash in on the prestigious prize.
