The 23-carat gold medal awarded to the late Alan Lloyd Hodgkin went under the hammer in Los Angles late on Thursday and was purchased by an unidentified private collector.
Bidding for the medal sold by Nate D. Sanders Auctions began at $450,000 dollars and shot up to $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.
Another Nobel Prize auctioned in May sold for $765,002.
Since early 2014, about 10 Nobel medals have gone up for auction as laureates or their families cash in on the prestigious prize.
