Coins of the Byzantine Empire represent the continuation of the Roman Empire in the East from the 4th to the 15th century, reflecting the political, religious and artistic development of Constantinople and its provinces. These issues include solidi, tremisses, folles, miliaresia and other gold, silver and bronze denominations, featuring frontal imperial portraits, Christian iconography, crosses, monograms and Greek inscriptions that shaped medieval numismatics. Byzantine coinage spans more than a millennium, from the monetary reform of Anastasius I to the fall of Constantinople, forming one of the most influential traditions of Late Antiquity and the Middle Ages.
