Nero Sestertius, RIC I (second edition) Nero 264

Monetary Context and Nero's Bronze Coinage Reform

The introduction of RIC I (second edition) Nero 264 occurred against the backdrop of one of the most comprehensive monetary overhauls of the early Roman Empire. Prior to approximately AD 64, the imperial administration had largely suspended the striking of base-metal denominations in Rome, relying instead on leftover Julio-Claudian issues and provincial supply. Nero's reform restructured the precious metal and aes coinages simultaneously. In the bronze and brass sector, the mint resumed full-scale production of all traditional denominations, from the quadrans up to the sestertius, experimenting briefly with the expanded use of brass, or orichalcum, across multiple denominations before settling into a more regularized standard. The sestertius remained the preeminent large-format coin of everyday high-value transactions and state expenditure. Valued at four asses or one quarter of a silver denarius, it commanded significant purchasing power within the Roman economy. Because of its expansive surface area, measuring roughly 34 to 36 millimeters in diameter with a nominal weight target centered around 26 to 28 grams, the sestertius was deliberately chosen by imperial authorities as a primary vehicle for monumental propaganda. The closing of the Temple of Janus, commemorated on this type, offered Nero a timely opportunity to justify his political stewardship and demonstrate imperial piety to the Roman populace following the devastating fire of Rome and costly military campaigns in the East.

Production and Mint Attribution

The type catalogued as RIC I (second edition) Nero 264 was produced exclusively at the imperial mint of Rome. In modern numismatic classification, establishing the origin of Neronian aes requires distinguishing between the products of Rome and those of the western branch mint active at Lugdunum (modern Lyon, France). The Rome mint is readily distinguished by stylistic and technical features: fine, naturalistic modeling of the imperial bust, high relief, elegant and balanced lettering, and the absence of the small globe that typically sits beneath the point of Nero's neck truncation on Lugdunum dies. Technically, RIC 264 was struck in orichalcum, a golden-toned alloy of copper and zinc favored for sestertii and dupondii due to its bright appearance and durability. The mint prepared heavy cast flans that were hammered between engraved iron dies. The die axes for this issue are generally adjusted to either six o'clock or twelve o'clock, reflecting the tight mechanical discipline of the metropolitan moneyers. The detailed execution of the architectural elements on the reverse die underscores the technical proficiency of the Roman die-sinkers, who were able to render latticework, masonry joints, and fabric garlands in miniature scale with striking clarity.

Obverse Design and Iconography

The obverse of RIC 264 presents a mature right-facing portrait of Nero. The emperor is depicted laureate, with the laurel wreath tied at the back of the head and its ribbon ties falling downward toward the nape of the neck. Distinctive to this specific catalogue entry is the presence of an aegis draped over the lower truncation or shoulder, an attribute traditionally associated with Jupiter and Minerva. In Hellenistic and early imperial iconography, the aegis symbolized divine protection and martial supremacy, subtly elevating the princeps to superhuman status. Nero's portraiture on this issue departs dramatically from the youthful, idealized forms seen on his earlier aurei and denarii from the regency period of Seneca and Burrus. Instead, the engraving exhibits the fleshy jawline, prominent neck musculature, and elaborate curls characteristic of his post-reform styling. The hair is arranged in a dramatic crown of locks brushed forward over the brow, reflecting contemporary Roman high fashion and theatrical self-presentation. The die-cutters at Rome captured both physical realism and imperial majesty, creating one of the most recognizable portraits in ancient numismatics.

Reverse Iconography: The Temple of Janus

The reverse composition of RIC 264 presents an architectural view of the Temple of Janus Geminus, located near the Roman Forum. Unlike conventional temples, the shrine of Janus was a passage or ceremonial gateway that was traditionally kept open during times of war and closed only when peace had been established throughout all territories of the Roman state. According to ancient tradition, the gates had been shut by King Numa, after the First Punic War, three times under Augustus, and not again until Nero. In the variant defined by RIC 264, the shrine is viewed from an angle showing the front or end wall with double folding doors on the right and a side flank with a large latticed window on the left. The double doors are depicted firmly shut, secured by a long ornamental garland draped across the entranceway. This design is often distinguished in numismatic literature as the 'terra door' variant, reflecting the door-to-right orientation. The latticed window and structural ashlar masonry of the shrine are carefully delineated, offering one of the few surviving contemporary architectural depictions of this ancient monument. Flanking the structure in the lower field are the letters S C (Senatus Consulto), denoting formal senatorial sanction for the issue.

Epigraphy and Legend Structure

The inscriptions on RIC 264 are integral to its political message, expressed in crisp, well-proportioned Roman capitals. The obverse legend reads: NERO CLAVD CAESAR AVG GER P M TR P IMP P P This continuous legend expands as 'Nero Claudius Caesar Augustus Germanicus, Pontifex Maximus, Tribunicia Potestate, Imperator, Pater Patriae'. It incorporates his adoptive Claudian lineage, his victory title Germanicus, his supreme religious office as chief priest, his annual grant of tribunician power, an imperial acclamation, and the honorific title 'Father of the Country'. The formula omits specific numbering for the tribunician power and imperial acclamations, a practice standard on Nero's reformed aes, creating a timeless imperial presentation rather than an issue bound to a single regnal year. The reverse legend provides the ideological justification for the image: PACE P R TERRA MARIQ PARTA IANVM CLVSIT Expanding to 'Pace Populi Romani Terra Marique Parta Ianum Clusit', this translates as: 'Having procured peace for the Roman people on land and sea, he closed the Temple of Janus'. The phrase echoes the Augustan Res Gestae and announces the resolution of Roman-Parthian tensions, particularly the settlement orchestrated by Corbulo regarding the Armenian throne, alongside the suppression of domestic unrest. Complemented by the letters S C in the lower fields, the legend presents an image of harmony between princeps, Senate, and the Roman state.

Typology and Chronological Placement

Within the typology of the second edition of Roman Imperial Coinage Volume I, Nero's Temple of Janus sestertii form an extensive series comprising several distinct die pairings and legend arrangements. The type RIC 264 is defined by a precise combination: the obverse portrait faces right, bears a laurel wreath, and features the aegis; the obverse legend employs the standard sequence ending in IMP P P; the reverse shows the temple with doors on the right and a latticed window on the left, paired with the full TERRA MARIQ legend and S C across the fields. Closely related types in the series include RIC 263, which shows the bare or laureate bust without aegis, and RIC 265 through 271, which feature alternative obverse headings, radiate crowns, or left-facing portraits. Furthermore, a parallel series struck at both Rome and Lugdunum reverses the perspective of the temple, placing the closed double doors on the left and the window on the right (frequently paired with the variant legend ending MARIQVE instead of MARIQ). While earlier numismatic chronologies dated the closure of the Temple of Janus under Nero to AD 64 or 65, scholarly consensus places the primary striking of this sestertius group between AD 65 and 66, following the public ceremonial closure of the shrine and Tiridates I's journey to Rome to receive the Armenian diadem.

Circulation, Hoard Evidence, and Survival

As part of the massive aes output of Nero's later reign, RIC 264 circulated widely across the Roman world. Sestertii struck at Rome supplied the Italian heartland as well as frontier garrison provinces along the Rhine and Danube, where demand for official Roman base-metal coinage was acute. Hoard evidence and archaeological excavation finds indicate that these large bronze pieces remained in active circulation for decades after Nero's death and subsequent damnatio memoriae. Because base-metal denominations were not systematically recalled, Neronian sestertii continued to function as currency throughout the Flavian period and well into the second century AD. Many surviving specimens display substantial wear consistent with prolonged commercial use over several generations. In addition, some examples recovered from northwestern provinces show evidence of contemporary countermarking, applied under the Flavians or provincial commanders to revalidate or extend the legal tender status of Julio-Claudian aes. RIC 264 remains one of the most celebrated bronze types of the early Roman Empire, both for its high sculptural artistic merit and its direct connection to pivotal diplomatic events of Nero's reign.
