CAESAR CAIVS FLAVIVS VALERIVS CONSTANTIVS AVGVSTVS

The coinage of Emperor Constantius I between 293 and 306 reflects the formation and development of the tetrarchy system. Constantius was appointed Caesar of the eastern part of the empire in 293. One of the main features of Constantius' coins is that the symbol of the Sun God, Sol Invictus, often appears on his profile picture. This symbol became increasingly important during the Tetrarchy, and Constantius was also fond of using it. Symbols of imperial power, such as the throne, scepter and shield, are often seen on the reverse side. Constantius' coinage was an important milestone in the development of Roman coinage. The emperor significantly increased the ratio of minting gold and silver coins, which served the economic stability of the empire. In addition, he introduced many innovations in the appearance of the money, which contributed to the representation of the tetrarchy system. Some characteristic types of Constantius' coinage: Gold solidus: This was the main gold coin of the tetrarchy period. The solidus of Constantius usually weighed 4.5 grams and contained 72% gold. Silver argenteus: This was the main silver coin of the Tetrarchy period. Constantius' argenteus usually weighed 3.5 grams and contained 90% silver.Bronze follis: This was the main bronze coin of the Tetrarchy period. The follis of Constantius usually weighed 10 grams. Coinage of Constantius is an important historical source for the period of the Tetrarchy. The emperor's coins are important evidence of the political, economic and cultural development of the empire.
