After winning the Nobel Peace Prize last October, the Russian journalist Dmitri A. Muratov said he thought the honor should have gone to a different Russian: the jailed opposition leader Aleksei A. Navalny.

Mr. Muratov, the editor of the independent newspaper Novaya Gazeta (who shared the prize with the journalist Maria Ressa of Rappler, a news outlet in the Philippines), later announced that he would donate his roughly $500,000 in prize money to support various charitable causes.

And now, Mr. Muratov — whose paper suspended publication in late March, saying Russia’s increasingly draconian press laws made it impossible to truthfully cover the war in Ukraine — is giving away the 23-karat gold Nobel medal itself.

On June 20, the medal will be sold in New York by Heritage Auctions. All proceeds will go to UNICEF, to help children who are refugees from Ukraine.
