Valens Bronze AE3, RIC IX Siscia 15B

Monetary Context and Denominational System

The monetary reforms initiated under Valentinian I and his brother Valens in 364 AD sought to stabilize an imperial currency system destabilized by decades of inflation and debasement. While solidi of high purity formed the bedrock of state accounting, taxation, and elite fiscal transfers, daily market transactions and municipal commerce depended on base-metal copper-alloy coinages. In modern numismatic literature, the bronze coinage of this period measuring between 17 and 19 millimeters in diameter is conventionally classified as an AE3, sometimes identified with the historical term centenionalis or nummus. RIC IX Siscia 15B represents the standard small-denomination bronze struck for Valens during the central years of the Valentinian dynasty. Unlike earlier Constantinian multi-denominational schemes, Valentinian base-metal production focused heavily on two paired thematic reverse types: Securitas Reipublicae and Gloria Romanorum. These issues were produced on an enormous scale to pay state functionaries, supply military garrisons along the Rhine-Danube frontier, and provide standard transactional tokens for the wider populace.

Mint Production and Workshop Organization at Siscia

The imperial mint of Siscia, situated at modern Sisak in Croatia, occupied a vital logistical node near the junction of the Sava and Kupa rivers. Its geographic position rendered it the principal mint for the diocese of Pannonia and a key supplier of base metal coinages for the Illyrian army. Siscia operated several distinct workshops, or officinae, which were routinely designated in the exergue by Greek letters such as Alpha, Beta, Gamma, or Delta following the mint signature SISC. RIC IX Siscia 15B was struck across these officinae over an extended period. Production control was maintained through an intricate sequence of subsidiary marks, including stars, dots, crosses, and letters placed in the left, right, or central reverse fields, alongside specific mint-mark abbreviations in the exergue like ASISC, BSISC, or intermediate variants. The high volume of surviving specimens indicates a standardized, mass-production workflow with strict diesinking oversight, resulting in uniform weights and consistent metallic compositions.

Obverse Portraiture and Imperial Iconography

The obverse of RIC IX Siscia 15B presents a right-facing bust of Valens, pearl-diademed, draped, and cuirassed. The imperial portrait adheres to the stylistic conventions of the later fourth century AD, prioritizing dynastic uniformity, stern authority, and simplified formal geometry over naturalistic individual likeness. The pearl diadem, composed of two parallel strands of pearls interspersed with circular or rectangular jewels, serves as the primary emblem of absolute imperial majesty, firmly established since the era of Constantine the Great. The combination of paludamentum (the imperial cloak) pinned at the right shoulder and the protective cuirass underneath emphasizes the emperor's duty as supreme commander of the Roman legions. At Siscia, the diesinking style displays crisp, linear features, with large eyes, a prominent nose, and neatly banded drapery folds that distinguish the mint's craftsmanship from contemporaneous products of eastern mints such as Constantinople or Antioch.

Reverse Iconography and the Personification of Victory

The reverse of the type features Victory advancing toward the left, holding a laurel wreath aloft in her right hand and a palm branch cradled against her left shoulder and arm. This iconographic type has deep classical roots, yet within fourth-century imperial ideology it conveyed a renewed theological and political message. Although Christianity was firmly rooted within the Valentinian court, the traditional personification of Victoria remained an indispensable symbol of state triumph, military success, and divine sanction. The wreath represented the traditional accolade bestowed upon the victorious commander, while the palm symbolized enduring peace won through military fortitude. On RIC IX Siscia 15B, Victory's dynamic posture, with billowing drapery and extended wings, signifies ongoing vigilance and protection. The image reaffirmed that the safety of the Roman state was actively preserved by the reigning emperors through their relentless defense of the Danubian and Pannonian borders.

Epigraphy and Legend Structure

The obverse legend on RIC IX Siscia 15B reads D N VALEN-S P F AVG, broken as indicated across the field behind and above the diadem. The formula expands to Dominus Noster Valens Pius Felix Augustus, translating as 'Our Lord Valens, Pious and Fortunate Emperor.' The adoption of Dominus Noster as a standard titular prefix reflected the absolute nature of late imperial rule, while the traditional epithets Pius and Felix emphasized moral integrity and divine blessing. The reverse legend reads SECVRITAS-REIPVBLICAE, broken neatly above the head of Victory. Meaning 'The Security of the Commonwealth' or 'Security of the Republic,' this legend reinforced the ideological parity shared between the western Augustus Valentinian I and his eastern counterpart Valens. Epigraphically, Siscia's letterforms are typically clear, sharp, and compact, although dies dating toward the end of the issue can exhibit occasional letter crowding or slight degradation due to the intense pace of die-cutting.

Typology and Chronological Classification

In the framework established by J. W. E. Pearce in Roman Imperial Coinage Volume IX, type 15 at Siscia encompasses the major SECVRITAS REIPVBLICAE issues struck during the third emission period of the mint, running from 367 AD to 375 AD. This broad issue was subdivided alphabetically by Pearce to distinguish the three co-ruling Augusti: 15A for Valentinian I, 15B for Valens, and 15C for the young Gratian, who was elevated to Augustus in August 367 AD. Within the catalogue entry for RIC IX Siscia 15B, dozens of minor sub-varieties exist, classified primarily by the complex succession of field symbols, including stars, crescents, letters (such as F, R, or symbols), and their exact combinations with officina signatures. Chronologically, this emission ceased around the death of Valentinian I in late 375 AD, after which the mint reorganized its typological output and adjusted reverse symbols under the subsequent joint reigns of Gratian, Valentinian II, and Valens.

Circulation, Hoard Evidence, and Archaeological Findspots

RIC IX Siscia 15B was produced in massive numbers and circulated extensively throughout the central and northern provinces of the Roman Empire. Excavations along the Danubian limes, military outposts in Pannonia, Moesia, and Noricum, as well as civilian settlements across northern Italy and the northern Balkans, regularly yield abundant specimens of this specific issue. Because copper-alloy coinage possessed low intrinsic value, individual pieces moved rapidly in everyday local transactions and were rarely retrieved from low-value lost contexts. Significant numismatic hoards containing hundreds or thousands of Valentinian bronzes, such as the Delos and Balkan hoards, confirm that Siscia was the predominant supplier of base currency in the Illyrian corridor. Wear patterns on recovered pieces indicate that these coins continued to circulate long after the catastrophic Roman defeat at Adrianople in 378 AD, remaining in circulation into the early fifth century AD until the ultimate collapse of regular bronze distribution in the region.
