Caracalla Silver Antoninianus RIC IV Caracalla 262A

Monetary Reform and Denominational Context

The introduction of the double denarius in early 215 AD stands as one of the most consequential currency reforms of the third century AD. Modern numismatists designate this coin as the antoninianus, deriving the name from Caracalla's formal imperial name, Marcus Aurelius Antoninus, although its ancient official denomination remains unrecorded in surviving administrative documents. Caracalla confronted substantial fiscal deficits brought on by the military expansionism of his reign, generous cash distributions to the urban populace, and a massive pay hike of fifty percent granted to the legionaries. The conventional silver denarius, which had undergone gradual debasement throughout the Antonine and Severan eras, could no longer support state budgets without accelerating inflationary pressures or exhausting treasury silver stocks. To bridge the gap between state revenue and imperial expenditure, the mint at Rome created the antoninianus as a overvalued credit currency. Rather than containing double the precious metal of the denarius, the newly inaugurated denomination was struck at approximately one and a half times the weight of a contemporary denarius, with an average fineness around fifty to fifty-five percent silver. By compelling market participants and soldiers to accept the coin at a face value of two denarii while expending far less silver in its manufacture, the imperial treasury captured an immediate profit of approximately twenty to twenty-five percent on newly struck bullion. RIC IV Caracalla 262A belongs to this initial, carefully controlled inaugural phase of the denomination in 215 AD, representing the beginning of a monetary trend that ultimately dominated Roman silver currency for the remainder of the third century AD.

Mint Operation and Metrology

RIC IV Caracalla 262A was struck exclusively at the primary imperial mint in Rome. During the middle of Caracalla's sole reign, the Rome mint was organised into several officinae (workshops) responsible for striking gold aurei, silver denarii, the newly introduced antoniniani, and a reduced output of orichalcum and copper aes denominations. The transition to producing antoniniani required adjusting flan-casting moulds to accommodate a broader diameter, typically ranging between 22 and 24 millimetres, compared to the 18 to 20 millimetres standard for the contemporary denarius. In terms of mass, the theoretical standard intended for the antoninianus in 215 AD was likely based on an alignment of sixty-four coins to the Roman pound (libra), yielding an ideal weight of approximately 5.08 grams, though observed specimens across the wider 215 AD series vary between 4.80 and 5.50 grams. Die axes for this issue are predominantly regular, adhering to a six o'clock or twelve o'clock die orientation typical of Severan workshop discipline. Metallurgical analyses of Severan silver from 215 AD indicate that while the alloy retained an appearance of bright silver due to surface-enrichment processes (pickling in organic acids to remove surface copper before striking), the core metal consisted of an argentiferous bronze containing significant trace elements of copper, tin, and lead. Die cutting at Rome maintained exceptionally high standards, with skilled engravers producing crisp, highly detailed portrait dies alongside intricate mythological reverses.

Obverse Iconography and Imperial Image

The obverse of RIC IV Caracalla 262A presents a right-facing bust of Caracalla wearing a radiate crown, draped across the shoulders, and occasionally rendered with cuirass details beneath the folds of the mantle. The radiate crown served as the primary visual signifier of the double denomination across the imperial coinage system, continuing a convention established during the early Principate where radiate crowns distinguished the dupondius from the laureate as, and double aurei from standard aurei. By adopting the radiate solar crown, Caracalla visually associated himself with Sol, a deity whose cult gained rising prominence under the Severan dynasty. The portraiture on this issue reflects Caracalla's mature, aggressive physiognomy, a marked departure from the softer, idealised portraits of his youthful co-rule with Septimius Severus. The emperor is depicted with a cropped, curly military beard, tightly coiled hair, and deeply set brow ridges intended to evoke the stern resolve and ferocity of a frontline commander. This stylistic transition was closely linked to his self-identification with Alexander the Great and his desire to project an uncompromising, soldier-emperor persona to the praetorian guard and the provincial armies.

Reverse Iconography and Mythological Symbolism

The reverse of RIC IV Caracalla 262A displays an unusual and arresting mythological composition. A male deity, typically identified in foundational catalogues as Pluto, sits facing left on a throne or low stool. He wears a polos or modius upon his head, an ancient cylindrical headdress associated with underworld and chthonic fertility deities, extending his right hand outward while grasping a vertical sceptre or staff with his left hand. To his left, positioned beside the seated figure, is an attendant animal described in RIC IV as a Minotaur. This curious cataloguing description in RIC IV.1 has generated substantial discussion among Severan numismatists. While the standard catalogue description explicitly records the attendant creature as a Minotaur, classical religious iconography strongly connects seated underworld deities wearing the polos with Serapis or Pluto, who is traditionally attended by the three-headed hound Cerberus rather than the Cretan Minotaur. In some die varieties, the compact, crouching depiction of the beast, sometimes displaying multiple heads or a heavy canine form, was evidently misidentified or recorded idiosyncratically during nineteenth- and early twentieth-century compilations. The syncretic fusion of Pluto and Serapis was heavily patronised by Caracalla, who famously visited the Serapeum in Alexandria and sought divine healing and divine legitimacy from chthonic and salvific gods to soothe his notorious physical and psychological ailments.

Epigraphy and Titulature

The legends on RIC IV Caracalla 262A provide precise historical and administrative context through imperial epigraphy. The obverse legend reads ANTONINVS PIVS AVG GERM, rendered in a clean, regular Severan epigraphic hand. This legend records his official nomenclature as Marcus Aurelius Antoninus Pius Augustus, complemented by the victory title Germanicus (abbreviated GERM). Caracalla formally assumed the title Germanicus in late 213 AD following his campaigns against the Alamanni along the Raetian and Upper German frontiers, making this epithet a standard feature of his later coinage. The reverse inscription, P M TR P XVIII COS IIII P P, articulates the emperor's official constitutional powers: Pontifex Maximus (chief priest), Tribunicia Potestate XVIII (holding tribunician power for the eighteenth time), Consul IIII (consul for the fourth time), and Pater Patriae (father of the fatherland). Because Caracalla's tribunician renewals occurred annually on December 10, the eighteenth tribunician power ran from December 10, 214 AD to December 9, 215 AD. Combined with his fourth consulship, entered in 213 AD, this epigraphic formula conclusively dates the production of the coin to the calendar year 215 AD.

Typology and Chronological Placement

RIC IV Caracalla 262A belongs to the very first emission of antoniniani produced at Rome in 215 AD. When Caracalla authorised the new denomination, the mint struck a diverse programmatic series of reverses to announce the coin to the army and civilian population. Companion types within the 215 AD emission featured traditional deities such as Jupiter, Mars, Venus, Sol, and Apollo, alongside personifications celebrating imperial virtues, including Fides Militum and Pax. Within this inaugural typology, the Pluto/Serapis reverse represented by RIC 262A forms a distinct and relatively scarce type compared to the more prolific Sol and Serapis standing types of the same year (such as RIC IV Caracalla 263 and 264). Die studies indicate that the seated Pluto/Serapis type was struck alongside denarii bearing similar reverse compositions, illustrating that the mint initially mirrored traditional denarius iconography onto the new, broader flans. By late 215 AD and early 216 AD (TR P XIX), the seated underworld motif had largely been phased out in favour of aggressive military and solar imagery, particularly Sol standing with raised hand and whip, which became the standard emblem of Caracalla's subsequent Parthian expedition.

Circulation, Hoard Evidence, and Reception

Despite the imperial government's attempt to establish the antoninianus as a standard circulating denomination, the public and market response in 215 AD was mixed. Hoard evidence from across the western and eastern provinces demonstrates that early antoniniani of Caracalla, such as RIC 262A, circulated alongside high-grade Severan denarii but did not immediately drive them out of use. Because the public recognised that two denarii contained substantially more silver than a single antoninianus, Gresham's Law took effect: older, finer denarii were frequently hoarded or melted down, while the overvalued antoniniani remained in active circulation or were spent quickly. Caracalla's antoniniani appear in significant numbers in military site finds and frontier hoards along the Rhine, Danube, and eastern frontiers, reflecting the reality that the denomination was primarily disbursed as legionary pay. Following Caracalla's death in 217 AD and the brief reign of Macrinus, production of the antoninianus ceased entirely under Elagabalus around 219 AD, only to be revived permanently under Pupienus, Balbinus, and Gordian III in 238 AD. As a result, genuine 215 AD specimens of RIC 262A survived in hoards buried during the turbulent mid-third century, frequently showing moderate to heavy circulation wear consistent with protracted use across two decades of monetary upheaval.
