Ново-Брдо
Serbian rulers had a custom of donating a certain amount of silver from Novo Brdo to various monasteries: Prince Lazar to Ravanica and Drenča, Despot Stefan Lazarević (r. 1389–1427) to Hilandar and Great Lavra, and Despot Đurađ Branković (r. 1427–1456) to Esphigmenou. In 1405, Despot Stefan donated an annual income of 100 pounds of silver from Novo Brdo to the Hilandar monastery. The law of the city of Novo Brdo is mentioned in 1439, which indicated that Novo Brdo in the 15th century was organized as a city municipality. Production of silver and gold peaked between 1420 and 1440.
