Nero Brass Sestertius RIC I (second edition) Nero 134

Monetary Reform and Denominational Setting

The sestertius catalogued as RIC I (second edition) Nero 134 belongs to the pivotal period following Nero's comprehensive monetary reform of AD 64. Before this reform, Nero's imperial mints had largely suspended the regular production of base-metal denominations, relying instead on precious metals alongside surviving Augustan, Tiberian, and Claudian copper and orichalcum pieces. When brass and copper issues resumed on an unprecedented scale, the monetary system was rebalanced with adjusted weight standards and revised metal compositions. In this reformed framework, the sestertius maintained its position as the premier base-metal coin, valued at four asses, two dupondii, or one quarter of a silver denarius. Unlike the red copper used for smaller denominations such as the as and quadrans, the sestertius was manufactured from orichalcum, a golden-hued zinc-copper alloy highly prized for its vibrant appearance and durability. The expansive flan of the sestertius, measuring between 34 and 37 millimeters in diameter, provided Roman celators with an ideal canvas for elaborate compositions that combined realistic portraiture with intricate state narratives. By deploying the orichalcum sestertius across domestic and administrative markets, the imperial administration both stimulated daily liquidity and reinforced civic confidence in the reformed monetary system.

Mint Organization and Production Technology

RIC 134 was struck exclusively at the primary imperial mint of Rome. Operating under strict administrative oversight, the Rome mint employed highly trained die engravers who achieved a level of sculptural relief and anatomical realism rarely matched in ancient numismatics. The manufacturing process began with the casting of heavy brass flans using carefully calibrated zinc-copper alloy batches. Blanks were subsequently heated to improve ductility before being placed between hand-carved bronze or iron dies. The obverse die was typically fixed within an anvil, while the reverse die was mounted into a handheld punch, struck by a heavy hammer. This manual method ensured slight variations in flan thickness, centering, and striking pressure across individual pieces, yet the overall weight standard was maintained with notable consistency around a median of approximately 26 to 28 grams. Die alignment for Rome during this phase was predominantly oriented at six o'clock or twelve o'clock, reflecting disciplined workshop procedures. The high relief of Nero's portrait and the multi-figure architectural tableau on the reverse required substantial striking force, frequently resulting in minor die-stress cracks along the flan borders.

Obverse Iconography and Imperial Image

The obverse of RIC 134 features a mature, laureate bust of Nero facing right, distinguished by the addition of an aegis at the base of his neck. Nero's portraiture on this issue reflects the fourth and final iconographic phase of his reign, characterized by a fleshy neck, stylized hair curls arranged in tiers over the forehead, and an intensely rendered facial structure. The presence of the aegis, a divine attribute associated with Jupiter and Minerva consisting of a protective goatskin adorned with serpents, elevates the emperor from human ruler to divinely protected sovereign. This motif conveys invulnerability and cosmic protection, subtly asserting the sacred authority of the Julio-Claudian princeps. The celators carved the portrait in deep relief, giving the imperial head a commanding physical presence on the broad brass field, framed neatly by the outer beaded border.

Reverse Iconography: The Adlocutio Cohortium

The reverse design presents the elaborate narrative scene known as the Adlocutio Cohortium, celebrating the formal address of the emperor to the Praetorian Guard. Nero appears bare-headed and clad in a civilian toga, standing facing left upon an elevated wooden or stone dais termed a suggestum. Standing alongside him on the platform is the praetorian prefect, traditionally interpreted as either Sofonius Tigellinus or Faenius Rufus, depending on the precise moment of striking. The emperor raises his right hand in the traditional oratorical gesture of adlocutio, addressing three praetorian guardsmen who stand on the ground level looking up toward him. The foremost soldier holds an eagle standard or signum, symbolizing the unit's fidelity and readiness. In the background behind the platform rises a substantial architectural composition consisting of a pillared colonnade surmounted by a battlemented or pedimented structure, commonly identified as a gateway or temple precinct within the Castra Praetoria. This sophisticated perspective composition creates a distinct sense of depth, underscoring the intimate bond between the emperor and his elite military protectors in Rome.

Epigraphy and Titulature Analysis

The epigraphic program of RIC 134 provides critical chronological and political markers for the reign. The obverse legend reads NERO CLAVDIVS CAESAR AVG GER P M TR P IMP P P, expanding to Nero Claudius Caesar Augustus Germanicus, Pontifex Maximus, Tribunicia Potestate, Imperator, Pater Patriae. The absence of specific iterative numbers for the tribunician power or imperial salutations leaves the legend standardized across multiple striking sessions, but the complete assembly of high titles, culminating in Pater Patriae (Father of the Country), demonstrates the mature phase of his titulature. On the reverse, the legend is divided into the explicit title ADLOCVT COH in the upper field or exergue, abbreviating Adlocutio Cohortium (Address to the Cohorts). Flanking the primary composition are the letters S C, standing for Senatus Consulto (by decree of the Senate). While the Senate's formal authority over bronze coin issues had become largely symbolic under the principate, the persistent inclusion of S C preserved constitutional tradition and granted outward legitimacy to the imperial regime's base-metal currency.

Typology and Chronological Classification

In the standard classification established by C. H. V. Sutherland in the revised second edition of Roman Imperial Coinage Volume I, type 134 is positioned within the extensive aes issues struck at Rome between AD 64 and roughly AD 66. While Sutherland's broader catalogue envelope for undated bronze issues extends from AD 62 to 68, the specific combination of the mature portrait, the aegis, and the expanded imperial titulature strongly anchors RIC 134 to the central period of post-reform production starting in AD 64. Numismatists distinguish RIC 134 from closely related sestertius types by its precise iconographic formula: Nero is depicted laureate to the right with an aegis, whereas neighboring types such as RIC 130 through 133 and 135 feature bare heads, left-facing portraits, or an absence of the aegis. Parallel issues bearing the Adlocutio Cohortium theme were also struck at the imperial mint of Lugdunum (Lyon), but the Lugdunum issues are readily differentiated by the presence of a globe at the point of the bust and stylistic differences in die carving. RIC 134 thus occupies a distinct position as an official Rome-mint release of the iconic military address design.

Circulation, Hoards, and Archaeological Context

As a principal denomination in daily commerce, the sestertius circulated vigorously throughout the central and western territories of the Roman Empire, including Italy, Gaul, the Rhine frontier, and Britannia. Archaeological excavation and stray find data indicate that Neronian orichalcum sestertii were extensively utilized for high-value domestic transactions, administrative payments, and long-distance trade. Because base-metal coinage was not subject to systematic remelting to the same degree as gold and silver, specimens of RIC 134 frequently remained in circulation for decades, often exhibiting substantial surface wear by the time they entered hoards of the second century AD under the Antonine emperors. Countermarks from the civil wars of AD 68 to 69 are occasionally attested on Neronian sestertii, reflecting regional authorities verifying or re-validating currency amidst political instability. The durable orichalcum alloy and substantial size of the denomination ensured that RIC 134 served an enduring economic function long after the political crisis that concluded Nero's reign.
