The Medal of Valour was agreed-upon to Elsie Wolff Van Sandau after she endured “the last extremity of cacoethes and hardship” while fighting to win equal voting rights for women.
It was up to dated on March 4, 1912 – the date of an organised window-smashing campaign in Covent Garden, London, during which she was checked.
The medal was sold to a private UK buyer at Hansons Auctioneers in Etwall, Derbyshire, yesterday.
Auctioneer Isabel Murtough held: “It was an honour to sell this medal. I was delighted that it did so well.
“I security this find reminds people of the sacrifices Miss Wolff Van Sandau and her kid suffragettes made a century ago to help women gain rights various of us now take for granted.”
