Byzantine Silver · Collecting Guide · Kinzer Coins

The miliaresion was a major Byzantine silver denomination that became one of the defining coins of the Middle Byzantine monetary system.

The miliaresion was introduced under Leo III and his son Constantine V, probably around AD 720. It did not bring Byzantine silver back after “centuries”: the empire had issued silver hexagrams in the seventh century. Instead, the miliaresion established a new and long-lived Middle Byzantine silver denomination with distinctive cross-and-inscription designs.

What Is a Miliaresion?

The miliaresion was a Byzantine silver coin introduced in the eighth century. The earliest issues name Emperor Leo III and his son and co-emperor Constantine V and are generally dated to about AD 720.

It circulated alongside Byzantine gold and copper coinage and remained an important silver denomination for centuries, with its weight, fineness, and design changing over time.

Did the Miliaresion Bring Silver Back to Byzantium?

Not after centuries. That wording overlooks the Byzantine hexagram, a substantial silver coin first issued under Heraclius in the seventh century and continued by several successors.

By the time the miliaresion appeared, regular production of the hexagram had faded. The miliaresion therefore represents a new phase of Byzantine silver coinage, not the first silver issue in many centuries.

The key chronology is hexagram in the seventh century, then miliaresion from the early eighth century.

Where Does the Name Miliaresion Come From?

The Byzantine Greek name miliaresion is historically related to the late Roman silver denomination called the miliarense.

They should not be treated as the same coin continued unchanged. The Byzantine miliaresion had its own weight standards, designs, and monetary history.

How Heavy Was a Miliaresion?

There was no single standard that remained unchanged throughout the denomination's long history.

  • Early issues: often around 2.2–2.3 grams
  • Many later issues: often closer to roughly 2.7–3 grams
  • Metal: silver, with fineness varying by period

Collectors should attribute a coin to its specific emperor and issue before judging whether its weight is normal.

What Appears on a Miliaresion?

Early miliaresia are famous for their largely inscriptional designs. A cross, often on steps, dominates one side while imperial and religious inscriptions fill the fields.

Unlike many Byzantine gold coins, the earliest miliaresia do not depend on an imperial portrait. Later issues became more varied, and some eventually incorporated portraits or busts.

What Was the Miliaresion Used For?

The denomination's precise role changed over time. The earliest issues may have had an important ceremonial or donative function, while later miliaresia clearly formed part of the circulating silver currency used in payments and exchange.

Because the coin remained in production for generations, it should not be assigned one narrow purpose for its entire history.

Who Issued Miliaresia?

Miliaresia were struck by many Middle Byzantine rulers, including Leo III, Constantine V, Nikephoros I, Michael II, Theophilos, Basil I, Leo VI, Constantine VII, Romanos I, Basil II, Constantine VIII, Constantine IX, Romanos IV, and Michael VII.

The series evolved substantially across those reigns, which is part of what makes it attractive to collectors.

What Replaced the Miliaresion?

The traditional miliaresion disappeared as the eleventh-century monetary system deteriorated and was superseded during the major reforms of Alexios I Komnenos in AD 1092, when Byzantium reorganized its gold, silver, and copper coinage.
