Macrinus Silver Antoninianus, RIC IV Macrinus 77d

Monetary Context and the Severan Double Denarius

The antoninianus was introduced into Roman monetary circulation under Caracalla in AD 215 to alleviate severe state fiscal pressures caused by military pay increases and expansive imperial expenditures. Although modern numismatists apply the term antoninianus based on late antique textual references to Antoninus, the ancient official name of this radiate silver piece remains uncertain, with scholars frequently proposing bicharactus or simply identifying it as a double denarius. The new denomination was tariffed at two denarii, yet its average weight of approximately five grams and its silver fineness of roughly fifty to fifty-two percent meant that it contained only about 1.5 times the precious metal content of a contemporary denarius. This overvaluation yielded a substantial seigniorage profit for the imperial treasury while simultaneously introducing inflationary pressures into the imperial market economy. Following the assassination of Caracalla near Carrhae in April AD 217, Marcus Opellius Macrinus ascended to the imperial purple as the first member of the equestrian order to achieve the throne. Confronted by an empty treasury, costly settlement negotiations with the Parthian Empire, and a legionary apparatus accustomed to exorbitant stipends, Macrinus faced critical choices regarding imperial monetary policy. Rather than expanding production of the overvalued radiate piece, Macrinus significantly scaled back the striking of antoniniani, focusing the bulk of his silver output on the traditional denarius. RIC IV Macrinus 77d belongs to this restricted group of radiate emissions struck at Rome, exemplifying the transitional status of the denomination immediately prior to its temporary cessation under Elagabalus and Severus Alexander.

Production Standards and Mint Organization

All standard authorities assign RIC IV Macrinus 77d to the primary imperial mint at Rome. Although Macrinus governed entirely from the Roman East and never physically set foot in the capital during his fourteen-month reign, the administrative apparatus of the Rome mint continued to execute imperial coin production based on imperial dispatches, official mandates, and traditional Senate-monitored mint procedures. Dies were cut by Rome's established engravers, who initially lacked immediate access to the living likeness of the new emperor, relying instead on official portrait models distributed from the eastern imperial headquarters. In terms of physical production, the antoninianus was struck from debased silver alloy flans prepared by casting circular blanks in open moulds before cold-trimming and hot-striking between two hand-held intaglio dies. The weight standard of the Rome mint's radiate issues under Macrinus fluctuated moderately around a median cluster of 4.8 to 5.2 grams, maintaining a diameter typically spanning between 21 and 23 millimetres. The metal composition mirrored late Caracallan standards, containing roughly fifty percent silver alloyed with copper and minor trace elements of lead and tin. Die orientation for RIC IV Macrinus 77d is predominantly regular, following the traditional vertical die alignment (either twelve o'clock or six o'clock) typical of the third-century Roman imperial mint.

Obverse Iconography and Imperial Regalia

The obverse of RIC IV Macrinus 77d presents a right-facing bust of the emperor wearing the radiate crown, the distinguishing diagnostic attribute of the double-denomination silver antoninianus and the double sestertius. In early imperial coinage, the radiate crown was closely associated with Sol and traditionally reserved for posthumous, deified emperors. Caracalla redefined this attribute as a living denomination marker, signaling a double value on both silver and bronze coinages. On RIC IV Macrinus 77d, the crown is rendered with sharply cut, prominent triangular rays bound at the base by a double or single diadem band tied behind the head. The specific variety catalogued as 77d is defined by its drapery and facial rendering. The imperial bust is depicted draped, with fabric folds gathered over the far shoulder and chest, rather than cuirassed or naked. Furthermore, the emperor is portrayed with a short, cropped beard, styled closely along the jawline. Numismatic scholars note that portraiture of Macrinus at Rome evolved in distinct phases: the earliest portrait models, produced before detailed likenesses arrived from the East, often resembled Caracalla or featured relatively youthful, clipped facial hair. This closely cropped beard contrasts with later emissions of AD 218 that depict Macrinus with an elongated, philosophical beard meant to accentuate his legal background and mature gravitas.

Reverse Typology: Jupiter the Preserver

The reverse of RIC IV Macrinus 77d is dedicated to Jupiter Conservator, one of the foremost protector deities of the Roman state and imperial authority. The composition depicts Jupiter standing facing left, represented predominantly nude in classical Hellenistic fashion, with his mantle or chlamys draped gracefully over his extended left arm and falling in vertical folds beside his flank. In his right hand, the deity holds a downward-pointing thunderbolt, symbolizing divine power and the capacity to strike down enemies of the empire. In his left hand, Jupiter holds a tall vertical sceptre or spear upon which he leans. The central thematic element of the design is the inclusion of a diminutive human figure standing before Jupiter at lower left. This figure depicts Emperor Macrinus himself, standing leftward beneath the outspread right arm and thunderbolt of the supreme deity. By depicting the emperor on a substantially smaller scale than the god, the design conveys the principle of divine patron-client hierarchy: the mortal sovereign rule on earth exists strictly under the shelter, sanction, and celestial protection of Jupiter. This iconography was especially poignant for an equestrian usurpation lacking dynastic blood ties to the Antonine or Severan lineages, serving as an urgent religious validation of the new ruler's precarious position.

Epigraphy and Imperial Titulature

The legends of RIC IV Macrinus 77d are executed in clean, classical Roman epigraphy, composed of uncial capital letters encircling the outer perimeter of both faces within beaded borders. The obverse legend reads IMP C M OPEL SEV MACRINVS AVG, an abbreviated formulation expanding to Imperator Caesar Marcus Opellius Severus Macrinus Augustus. The inclusion of Imperator as a praenomen emphasizes supreme proconsular and military command, while Caesar and Augustus confirm supreme imperial status. Notably, Macrinus adopted the prestigious cognomen Severus to fabricate ideological continuity with the popular dynasty of Septimius Severus and Caracalla, seeking to win the wavering loyalty of the Danube and Syrian legions. The reverse inscription reads IOVI CONSERVATORI, cast in the dative case to signify a dedicated offering: 'To Jupiter the Preserver' or 'To Jupiter the Protector.' Dedications in the dative were standard in Roman religious practice when commemorating divine intervention or securing continued supernatural guardianship. The absence of specific tribunician numbers, consulship designations, or imperatorial acclamations on the reverse distinguishes this thematic issue from strictly dated administrative coinages, allowing the message of divine protection to remain continuously relevant throughout the issue period.

Typological Classification and Chronological Placement

Within the typology established by Harold Mattingly and Edward A. Sydenham in Roman Imperial Coinage, type 77 encompasses the Rome mint's antoniniani dedicated to Jupiter Conservator, with lowercase letter suffixes designating specific obverse bust variations. Type 77d is specifically distinguished by the combination of the radiate crown, cropped beard, and draped bust facing right, differentiating it from cuirassed or draped-and-cuirassed companions such as types 77a through 77c. Chronologically, this issue spans the period between the accession of Macrinus in April AD 217 and his fall in June AD 218. The presence of the short, cropped beard points toward the earlier half of this reign, likely beginning in the summer or autumn of AD 217 when the Rome mint received initial imperial instructions to strike coins in the name of the new Augustus. While some scholars have attempted to divide Macrinus's undated coinage into strict chronological tranches based on beard length, hoard associations show that dies with shorter beards remained in service alongside longer-bearded portraits into early AD 218. Production of type 77d ceased entirely when news of Macrinus's defeat at Antioch and subsequent execution reached the capital in mid-AD 218.

Circulation, Hoard Evidence, and Monetary Impact

The circulation life of RIC IV Macrinus 77d was shaped by its limited original mintage and the volatile monetary history of the third century. Because Macrinus restricted the striking of antoniniani, specimens of his radiate double denarii appear in hoards in far smaller quantities than his contemporary denarii or the earlier mass emissions of Caracalla. Antoniniani of Macrinus that did enter circulation traveled alongside prevailing Severan silver throughout Italy, Gaul, the Rhineland, the Danube frontier, and the East. When Elagabalus succeeded Macrinus in AD 218, antoninianus production continued intermittently before being officially suspended around AD 219. As a consequence, existing antoniniani of Caracalla and Macrinus circulated in diminishing quantities until Gordian III revived the denomination on a massive scale in AD 238. During the extreme currency debasements of the mid-third century under Decius, Valerian, and Gallienus, earlier higher-grade silver issues like RIC IV Macrinus 77d were heavily hoarded and melted down for their superior intrinsic bullion value. Surviving examples are primarily preserved in mid-century frontier hoards buried during times of military instability, frequently showing moderate to significant signs of surface wear from decades of secondary circulation.
