Information |
A Byzantine gold denomination of the 1092 reform of Alexios I Komnenus (1081-1118), produced until 1355, during the reign of John V (1341-1376). The nominal value of the Hyperpyron is 24 carats, its actual value is ca. 20 ½. Gold content will steadily decrease in time, down to 11 carats. Because of the concave fabric, it is also termed trachy Hyperpyron. It will remain the money of account after 1355. It was not struck under John VI sole reign (1390) or in the later years of John V (1390-1391). Also produced under the divided empire in Nicaea and Bulgaria. |
