Nero Dupondius, RIC I (second edition) Nero 112

Monetary Context and the Neronian Currency Reform

The monetary landscape of Nero's later reign underwent a profound transformation around AD 64, coinciding with fiscal demands following the Great Fire of Rome and wider economic restructuring. In the early imperial denomination scheme established under Augustus, the sestertius and dupondius were struck in orichalcum (a bright golden copper-zinc alloy), while the as, semis, and quadrans were produced in unalloyed red copper. Nero's mint administrators embarked on a radical experiment that initially introduced orichalcum across all base-metal denominations, including fractions down to the semis and quadrans, before partially returning to traditional metals. Within this dynamic reorganization, the dupondius maintained its tariffed value of two asses (or one-half sestertius, one-eighth denarius). Because the experimental use of orichalcum across other denominations risked confounding market users accustomed to distinguishing the dupondius by metal alone, clear visual differentiators became necessary. While some early reformed strikings carried numeral marks of value, such as 'II' for the dupondius, the primary lasting innovation was the radiate crown on the obverse portrait. Originating as a solar attribute associated with Apollo and Sol, the radiate crown became the definitive numismatic sign of a double-denomination, a convention that endured for centuries into the radiate antoninianus of the third century AD. RIC I (second edition) Nero 112 embodies this reformed monetary structure, exhibiting the standard radiate bust alongside traditional senate-authorized bronze marks.

Production Standards and Rome Mint Manufacture

RIC I (second edition) Nero 112 was produced exclusively at the primary imperial mint of Rome. Following a decade of reign during which base-metal issues were largely absent or constrained to small fractions, the Rome mint resumed intensive production of sestertii, dupondii, and asses around AD 64. The mint workshop prepared high-quality orichalcum flans, formulated from copper alloyed with roughly 15 to 20 percent zinc. This zinc-rich composition gave newly minted specimens a lustrous, golden sheen distinct from unalloyed copper. The target weight standard for Neronian dupondii hovered around 13 to 14 grams, with typical diameters ranging between 28 and 30 millimeters, although individual flan preparation permitted substantial tolerance ranges typical of ancient fiduciary coinage. Die cutting at Rome during this period achieved a remarkable level of artistry. Engravers employed three-dimensional modeling, incising deep dies that captured Nero's full neck, elaborate coiffure, and fleshy facial features. Production involved manual striking between two dies using heavy hammers, with flans typically aligned along a regular six-o'clock or twelve-o'clock die axis.

Obverse Iconography and Imperial Representation

The obverse of RIC I (second edition) Nero 112 features a mature, radiate head of Nero facing right. The treatment of the portrait reflects the distinct court style of the emperor's later years, which broke away from the classicizing, idealized Julio-Claudian conventions in favor of a powerful, baroque naturalism. The portrait depicts Nero with a thick, columnar neck, a fleshy double chin, and a distinctive hairstyle known as the 'coma in gradus formata', arranged in tiers of waves radiating outward from the crown and framing the forehead and nape. The radiate crown itself consists of stylized, pointed solar rays secured by a band around the head. Beyond serving as a practical denominational badge for the dupondius, the radiate crown carried profound ideological overtones. By assimilating the living ruler to Sol, the god of the sun, the iconography underscored cosmic harmony, imperial vigilance, and the dawn of a prosperous golden age under the sovereign. The high relief of the Rome dies lent the portrait a statuesque presence, conveying dynastic authority across the empire.

Reverse Design: The Securitas Augusti

The reverse of the type features Securitas, the divine personification of imperial safety, tranquility, and freedom from peril. She is shown seated facing right on an ornate, high-backed throne or curule-style chair. Her upper body is bare to the waist, with a himation or drapery wrapped gracefully around her lower limbs. In a pose symbolizing profound confidence and repose, she rests her head languidly against her right hand, her elbow supported by the back of the seat, while her left hand loosely holds a short sceptre resting on her lap. Positioned in front of the seated goddess stands a low, garlanded altar upon which a sacrificial flame burns. Leaning against this altar is a lit torch, its base supported on a bucranium (the decorative skull of a sacrificed ox). The juxtaposition of the relaxed goddess with the active sacred altar and torch signifies that public tranquility is safeguarded by ongoing religious piety, imperial sacrifice, and celestial favor. Below or around the composition, the abbreviation 'S C' (Senatus Consulto) confirms that the issue was authorized under the formal constitutional sanction of the Roman Senate.

Epigraphy and Titulature

The obverse inscription of RIC I (second edition) Nero 112 reads NERO CLAVD CAESAR AVG GER P M TR P IMP P P. Transcribed in full Latin, the titles represent 'Nero Claudius Caesar Augustus Germanicus, Pontifex Maximus, Tribunicia Potestate, Imperator, Pater Patriae'. This formula represents the comprehensive accumulation of imperial honors: divine descent through adoption into the Claudian line, the cognomen Germanicus inherited through Drusus and Germanicus, the chief priesthood (Pontifex Maximus), annual tribunician power (Tribunicia Potestate), military acclamation (Imperator), and the honorary title Father of the Fatherland (Pater Patriae). The reverse legend reads SECVRITAS AVGVSTI, meaning 'the Security of the Emperor' or 'the Augustus's Security'. This phrase encapsulates the theological and political pact between princeps and populace: through the benevolent guardianship and tireless vigilance of the emperor, the state, its citizens, and its social fabric remain shielded from domestic sedition, famine, and foreign hostility. The epigraphy is executed in clean, classical Roman capital letters, set neatly within the circular beaded borders characteristic of the Rome mint.

Typology and Chronological Classification

Within the typology established by C. H. V. Sutherland in the revised Roman Imperial Coinage (RIC), volume I, Nero 112 occupies a specific place among the reformed base-metal issues struck at Rome. Nero did not issue extensive brass and copper coinage at Rome between AD 54 and roughly 64, leaving local circulation reliant on worn Julio-Claudian pieces and provincial strikings. When the Rome mint commenced base-metal operations, it produced dupondii with several reverse motifs, most notably Securitas Augusti, Victoria Augusti, and the Macellum Magnum. RIC 112 is strictly differentiated from its counterparts by a precise combination of attributes: a radiate head right (rather than left or bare/laureate), the uninterrupted full titular obverse legend ending in 'P P', and the rightward-seated Securitas beside the garlanded altar and torch. Related types, such as RIC 113 through 118, feature alternative portrait directions, slightly differing legend breaks, or Securitas seated to the left. Sutherland classified RIC 112 as belonging to the principal reform issues produced between approximately AD 64 and 66, although mint activity may have extended into 67 or 68. This chronological grouping is corroborated by portrait typology and the consistent presence of the title Pater Patriae, accepted by Nero in AD 55.

Circulation, Hoarding, and Archaeological Context

Dupondii of the reformed Neronian series entered monetary circulation across a broad geographic territory, circulating extensively through central Italy, Gaul, the Rhine frontier, and the Danubian provinces. In everyday retail trade, the dupondius occupied a vital intermediate niche, facilitating transactions too large for copper asses but below the value of silver denarii. Its golden color and radiate crown ensured immediate recognition in commercial exchanges throughout the western empire. Archaeological finds in military camps and urban settlements demonstrate that Neronian orichalcum dupondii remained in circulation long after Nero's death. Following the turbulent civil wars of AD 68 to 69, Flavian emperors continued the production of radiate dupondii using the same denominational convention. Hoard evidence indicates that Neronian dupondii circulated well into the second century AD, often showing considerable surface wear and gradual loss of their original golden patina, turning to deep olive and brown patinas in archaeological strata.
