Macrinus Copper-Alloy As, RIC IV Macrinus 166c

Monetary Context and Historical Setting

The monetary system under Macrinus inherited substantial fiscal strain following the heavy military spending and currency debasements enacted during the Severan era. After the assassination of Caracalla near Carrhae in April AD 217, Macrinus, then Praetorian Prefect, was acclaimed emperor by the legions in Mesopotamia. One of his primary challenges was resolving the ongoing war with the Parthian Empire. Following the costly engagement at Nisibis in AD 217, Macrinus concluded a settlement with King Artabanus IV that required enormous financial indemnities. Despite these substantial territorial and monetary concessions, imperial communiques sent to the Senate framed the resolution as a glorious victory, designated as Victoria Parthica. The base-metal coinage struck at Rome served as an important medium through which the imperial administration disseminated this official narrative to the Italian population and the Senate. The denomination of the as represented the standard fractional copper-alloy coin within the daily transactional economy, functioning alongside the larger orichalcum sestertii and dupondii. Although silver denarii and antoniniani formed the core of state military pay, the production of aes coinage at Rome reinforced civic legitimacy and maintained small-denomination liquidity across commercial centers.

Production and Mint Organization

The entire series of imperial aes coinage for Macrinus, including the as categorized as RIC IV Macrinus 166c, was produced at the primary imperial mint in Rome. Even though the emperor himself remained in the eastern provinces throughout his entire reign and never entered the capital as Augustus, the senatorial mint at Rome continued standard operations under official imperial directives transmitted from his headquarters in Antioch. The manufacturing of the as involved casting blank flans from refined copper or bronze alloys, which were then struck between engraved dies. Die carvers at Rome produced both obverse portraits and reverse allegorical scenes based on traditional Severan typological models and written imperial dispatches. Because Macrinus never visited Rome, early coin portraits created at the capital often bore an idealized or Severan-influenced appearance, gradually evolving toward a more individual physiognomy with a fuller beard and distinct facial profile as accurate models or descriptions reached the mint. Quality control in the bronze officinae remained relatively consistent, though the volume of base-metal striking under Macrinus was markedly smaller than during the reigns of Septimius Severus or Caracalla.

Obverse Iconography and Regalia

The obverse of RIC IV Macrinus 166c displays the imperial bust of Macrinus facing right. In keeping with the precise classification of subtype 166c, the portrait combines three distinct iconographic attributes: the laurel wreath, drapery, and a cuirass. The laurel wreath served as the quintessential Roman symbol of triumph and civil authority, standard for depictions of the Augustus on the as. The presence of both the cuirass and paludamentum or drapery over the shoulders underscored Macrinus's military role as imperator and supreme commander of the Roman legions, even as his lack of aristocratic senatorial background made traditional military imagery vital for legitimizing his authority. The stylistic execution of the bust reflects the mature portraiture of his reign, typically featuring cropped hair, a neatly delineated beard, and a solemn expression. Die variations among surviving specimens reflect subtle stylistic differences across different engravers at the Rome mint, though the presence of the complete imperial regalia remained standard for this catalogued subtype.

Reverse Design and Typology

The reverse design presents an elaborate allegorical representation of imperial victory. Winged Victory is depicted draped and seated facing right, resting upon a cuirass. She is poised to write an inscription upon an oval or round shield that rests firmly upon her left knee. In the field immediately behind her figure, an assemblage of captured weaponry is visible, including an additional shield and associated arms. This iconographic type is deeply rooted in Roman victory symbolism, echoing motifs used since the early empire where Victory records the triumphs of the emperor or the vows of the state on a dedicatory shield. In this specific context, the design explicitly commemorates the settlement with Parthia, framing diplomatic concessions as an armed triumph. The captured arms behind the seated figure emphasize the submission of barbarian equipment to Roman arms. Flanking the design in the lower field or exergue are the letters S C (Senatus Consulto), validating the issue under traditional senatorial sanction for base-metal coinage.

Epigraphy and Titulature

The legends on RIC IV Macrinus 166c provide vital chronological and ideological data. The obverse reads IMP CAES M OPEL SEV MACRINVS AVG, expanding to Imperator Caesar Marcus Opellius Severus Macrinus Augustus. Here, the adoption of the name Severus was an intentional dynastic device designed to associate Macrinus with the popular memory of Septimius Severus and retain the loyalty of the army. The reverse legend is fully inscribed as VICT PART P M TR P II COS II P P S C, which expands to Victoria Parthica, Pontifex Maximus, Tribunicia Potestate II, Consul II, Pater Patriae, Senatus Consulto. The epithet Victoria Parthica explicitly designates the Parthian victory. The imperial titles document Macrinus's second renewal of tribunician power (TR P II) and his entry into his second consulship (COS II), both of which were celebrated on January 1, AD 218. The inclusion of Pater Patriae confirms his formal acceptance of the title Father of his Country from the Senate.

Typological Differentiation and Chronological Placement

Within the Roman Imperial Coinage framework, type 166 forms part of the base-metal series commemorating the Parthian victory. The catalogue divides type 166 into lettered subtypes based on the arrangement of the obverse portrait. Subtype 166a features a laureate bust right with no drapery or cuirass, subtype 166b displays a laureate and draped bust right, and subtype 166c specifically designates the laureate, draped, and cuirassed bust facing right. The type is precisely dated to AD 218 by the explicit combination of TR P II and COS II. Because Macrinus assumed the second consulship on January 1, AD 218, and was overthrown following the Battle of Antioch on June 8, AD 218, the striking of RIC IV Macrinus 166c was confined to a window of roughly five months. Production was definitively halted when news of his defeat and death reached Rome, leading to the immediate retooling of the mint for Elagabalus.

Circulation, Survival, and Numismatic Evidence

Due to the brief chronological window of Macrinus's reign, his aes issues are markedly less common than those of his immediate predecessors or successors. The as circulated primarily within Italy and the western provinces, where base-metal copper and bronze coinage formed the backbone of local retail transactions. Archaeological site finds and hoards from Britain, Gaul, the Rhine frontier, and Italy demonstrate that asses of AD 218 entered circulation alongside worn Severan, Antonine, and even Flavian bronze pieces. Because base-metal denominations were not systematically recalled upon an emperor's damnatio memoriae, specimens of Macrinus continued to circulate until worn smooth or retired during the severe monetary disruptions of the mid-third century. Surviving examples of RIC IV Macrinus 166c in modern public collections and excavation inventories are relatively scarce, reflecting both the restricted original mintage and the attrition typical of ancient fractional bronze currency.
