Dukes Johan and Karl Blodsklipping 4 Mark
Blood clipping 4 Mark, Dukes Johan and Karl, 1568. After Erik XIV's murder of both her husband Svante Sture and her two sons in the Sture murders in 1567, Märta Leijonhufvud was awarded a compensation of 270 kg of pure silver as penance. She used parts of this treasure to finance the dukes Johan and Karl's coup d'état against Erik, among other things by having these coins minted, which therefore came to be called blood clippings. After the coup succeeded and put Johan III on the throne, in 1570 she was granted her husband's county, now enlarged and the fifth largest in the kingdom, which gave her the nickname "King Märta".
