A spokesperson for Heritage Auctions, which handled the sale, could not confirm the identity of the buyer but said the winning bid was made by proxy. The $103.5 million sale translates to $100 million Swiss francs, hinting that the buyer is from overseas.
The live auction happened on World Refugee Day. Previously, the most ever paid for a Nobel Prize medal was $4.76 million in 2014, when James Watson, whose co-discovery of the structure of DNA earned him a Nobel Prize in 1962, sold his.
Three years later, the family of his co-recipient, Francis Crick, received $2.27 million in bidding also run by Heritage Auctions.
