Roman Empire. Constantine I (AD 306-337). Follis Commemorative Series, AD 330-354. Æ Follis, Cyzicus mint. 330 or 334 AD. / (R5) Extremely Rare! (No reserve price)

The Follis from the time of Constantine I, minted in Cyzicus around 330 or 334 A.D., commemorates an era marked by the Christianization of the Roman Empire and significant administrative reforms. Constantine I, who ruled from 306 to 337 A.D., was famed for unifying the empire and endorsing Christianity. The Follis was a large bronze coin introduced in the early 4th century as part of monetary reforms to stabilize the empire's economy. Cyzicus, an ancient city in Asia Minor, was an important mint location for imperial coinage. Coins from this commemorative series bear various inscriptions and images honoring Constantine’s achievements and legitimacy as Augustus. The rarity of this Follis (graded R5 for rarity) makes it a prized piece for collectors interested in the Constantinian era’s numismatic history. Its survival offers tangible insight into the shifting political and religious landscape of late Roman antiquity.
