Arles Miliarensis

The miliarensis was a silver denomination of the late Roman Empire, larger and heavier than the small silver siliqua and struck as part of the reformed coinage introduced in the 4th century AD. The example shown here is attributed to the western mint at Arles (ancient Arelate) in southern Gaul, one of the empire's major late-Roman minting centers. It carries a pearl-diademed imperial bust of Constantine the Great or one of his successors and, on the reverse, a standing military figure holding a spear and shield.

As a silver piece of relatively high value, the miliarensis sat between the everyday bronze coinage and the gold solidus in the late Roman monetary system. Coins of this type were struck in modest numbers and are considerably scarcer today than the base-metal issues of the same emperors, making them a prized ancient silver type for collectors of the Constantinian and post-Constantinian era.

The miliarensis appeared as part of the coinage reforms that followed Constantine the Great's introduction of the gold solidus in the early 4th century AD. It was a silver denomination struck alongside the smaller siliqua, and its name is generally understood to relate to its value in relation to the gold coinage rather than to any single fixed rate, which shifted over time.

Mint marks in the exergue tie individual coins to specific workshops, and the mint of Arelate (Arles) was among the western mints active through much of the 4th century; the city was renamed Constantina for a period in Constantine's honor. Miliarenses were issued under Constantine and continued under his sons and later 4th-century emperors, typically bearing military and dynastic reverse imagery that projected imperial strength.

Because they were silver and of comparatively high value, these coins circulated less heavily than bronze and were more often hoarded, which is one reason surviving examples exist but remain uncommon. Precise mintage figures for ancient coins are not recorded, so all quantities are estimated from surviving specimens and hoard evidence.

Identify this type first by metal and size: the miliarensis is a silver coin, broader and heavier than the thin siliqua but smaller than a gold solidus. The obverse of this example shows a right-facing imperial bust wearing a pearl diadem, the beaded headband that marks Constantinian-era and later emperors, surrounded by a Latin legend giving the ruler's name and titles.

The reverse depicts a standing figure in military dress holding a spear and a shield, a common late-Roman device emphasizing the emperor or the army. Read the exergue (the space below the ground line) for the mint mark; an Arles attribution rests on marks such as those beginning with the letters for Arelate or Constantina. The precise legends and mint letters, not just the general design, are what pin the coin to a specific emperor, mint, and issue.

Condition, centering, and full legibility of the legend and mint mark are important both for attribution and for value, since worn or clipped silver can obscure the very details needed to identify the piece.

As a scarce late Roman silver denomination, the miliarensis is a higher-value ancient coin than the common bronze issues of the same period. Genuine examples generally trade from the low hundreds of dollars up into the low thousands, depending heavily on the emperor, mint, sharpness of strike, surface quality, and completeness of the legends and mint mark.

Well-centered coins with clear portraits, full inscriptions, and an unambiguous Arles mint mark command the strongest premiums, while worn, clipped, or corroded pieces sell for considerably less. Rarer emperors or unusual reverse types can push prices higher still.

Because these figures are broad ranges rather than fixed prices, any specific valuation depends on professional attribution and current market conditions. For a coin of this value it is worth obtaining an expert opinion or reputable dealer certification before buying or selling.
