Edith Cavell, the British nurse executed by the Germans during the First World War, is to be featured on a new commemorative £5 coin.
The coin will form part of a commemorative set to be issued next year by the Royal Mint marking the centenary of the war.
Miss Cavell worked as a nurse in German-occupied Belgium where she helped save the lives of soldiers from both sides.
She was shot by a German firing squad for helping Allied soldiers to escape across the border into the Netherlands.
Treasury minister Nicky Morgan said: "She showed true bravery by helping injured soldiers, regardless of their nationality, and it is right that she should be honoured as a British hero.
"She risked her life to help Allied forces escape and in doing so paid the ultimate price. It is important that we remember the sacrifices made by so many people in different ways during the war."
