Branko issued his own regional coins, the 'Helmet dinars', only one of three existing prior to the fall of the Serbian Empire. He ruled until his death in 1352, when he was accidentally killed by Vuk Kosača during a hunt. Branko's relatives later avenged his death in 1359, when they murdered Vuk.
He was succeeded by his son Radič Branković, Lord of Braničevo.
