solidus

Byzantine coin
Also known as: bezant

Quick Summary

The solidus was the primary gold coin of the Byzantine Empire, originating from the coin of Constantine. It weighed approximately 4.5 grams and was known for its purity for centuries, dominating European trade until the 13th century.12

Byzantine coinage, which began with Emperor Anastasius I, included gold, silver, and bronze. The gold solidus was a significant influence on European coinage for 1,000 years. The coins often featured religious imagery, reflecting the empire's Christian nature, with emperors depicted as Christian rulers.12

While the gold solidus was paramount, silver coins like the siliqua and keration, and later the miliaresion and hexagram, were also issued. Bronze coins were common and underwent reforms, with marks indicating their value. Constantinople was the main mint, but other cities also produced coinage. The solidus's purity declined from the 10th century, and by the later Byzantine period, coinage quality deteriorated significantly.123
