The Ancient Rome Constantine the Great AE Coin is a bronze coin (known as an AE follis) minted during the reign of Emperor Constantine I, who ruled from 306 to 337 CE. Pieces like the one recently sold exemplify the small bronze denominations known as AE3 or AE4, widely circulated throughout the Roman Empire during this transformative period. These coins were produced in mints across the empire, including Rome, Antioch, Alexandria, and Thessalonica, often marked with letters in the exergue indicating their place of origin.
On the obverse, the coin typically features a right-facing portrait of Constantine the Great, shown wearing either a laurel wreath, rosette diadem, or pearl crown, depending on the specific minting period. The surrounding Latin inscriptions read “CONSTANTINVS AVG” or similar titles, affirming his authority as emperor. The reverse sides varied widely—some display the Roman god Sol Invictus standing with a globe, others depict Jupiter holding Victory, or representations of military standards and city gates symbolizing stability and unity across the empire.
The AE coin series reflects the dramatic religious and political changes Constantine initiated. Following his historic vision at the Battle of the Milvian Bridge in 312 CE, Constantine embraced Christianity and legalized it throughout the empire, establishing the foundation for a Christian Rome. Later issues of his coins even incorporated Christian symbols such as the Chi-Rho (☧), marking the first instances of Christian imagery appearing on imperial coinage—a radical shift from traditional Roman polytheistic themes.
These Constantine AE coins hold both historic and cultural value. They circulated among the common people at a time when the empire transitioned from crisis to renewed unity under one ruler. Each coin thus serves as a tangible piece of one of history’s most significant turning points, connecting the classical and Christian eras. The AE denomination also marked Constantine’s monetary reforms, which standardized bronze coinage across the empire and simplified daily commerce.
In summary, the Ancient Rome Constantine the Great AE Coin is a bronze artifact from one of Rome’s most pivotal emperors, renowned for its elegant portraiture, varied reverse designs, and deep symbolic significance. It embodies an era when the empire was being reshaped politically, religiously, and economically—making it a prized piece for both collectors and history enthusiasts.
