Why This Coin Matters

The AE4 was the smallest circulating bronze coin of the late Roman Empire.

Used for everyday purchases in markets, workshops, military camps, and towns across the empire, these tiny coins passed through countless hands, making them some of the most familiar objects in daily Roman life.

During the reign of Theodosius I, they also witnessed one of history's greatest transformations.

When Theodosius became emperor in AD 379, the Roman world was still recovering from the devastating defeat at Adrianople, where Emperor Valens and much of the eastern field army had been destroyed. Over the next sixteen years, Theodosius rebuilt the Eastern Empire, defeated rival emperors in the West, and briefly reunited the Roman world under a single ruler.

He would be the last emperor ever to do so.

His reign also transformed the empire religiously. In AD 380, the Edict of Thessalonica declared Nicene Christianity the official religion of the Roman Empire. Over the following years, imperial legislation increasingly restricted traditional pagan worship while strengthening the role of Christianity within Roman government and society.

When Theodosius died in AD 395, he divided the empire between his sons Arcadius in the East and Honorius in the West.

Unlike earlier administrative divisions, this separation proved permanent.

The Eastern Roman Empire continued for nearly another thousand years as what historians now call the Byzantine Empire, while the Western Roman Empire gradually declined and disappeared in the fifth century.

These tiny AE4 bronzes circulated throughout both halves of the empire during the final years when Romans from Britain to Egypt still belonged to a single imperial state.

More than an ancient coin, it is a tangible reminder of the last moment Rome stood united.
