Marcus Aurelius Sestertius, RIC III Marcus Aurelius 1171

Monetary Context and Denominational Function

The sestertius was the primary high-value token denomination in the Augustan monetary system that persisted through the high imperial era. Valued at one-quarter of a silver denarius or four copper asses, the sestertius served as an essential medium for substantial daily cash transactions, local treasury reserves, accounting tallies, and official disbursements throughout the western and Danubian provinces. In the late Antonine period, imperial brass denominations were manufactured from orichalcum, a copper-zinc alloy that originally provided a golden-yellow visual distinction from pure red copper fractions. Although progressive metallurgical recycling through the second century AD caused gradual zinc depletion across the imperial aes series, the sestertius retained its authoritative role as the largest and most communicative circulating brass coin in urban markets. Within this framework, RIC III Marcus Aurelius 1171 filled both a transactional role in market circulation and an ideological role, disseminating the emperor's expanded victories and fiscal equity to civilians and military units alike.

Production Technology and Mint Attribution

All imperial sestertii of RIC III Marcus Aurelius 1171 were struck exclusively at the principal state mint located in Rome. The centralized metropolitan mint maintained organized workshops (officinae) capable of casting heavy round flans and striking them under great pressure using high-relief dies. Flan preparation involved pouring molten copper alloy into open or two-part molds, frequently leaving bevelled edges or trace casting sprues that were smoothed prior to striking. Coin dies were hand-cut by experienced celators using steel gravers, drills, and punches. The dies were subjected to intense concussive stress during striking, which led to progressive mechanical die wear, cracking, and eventual replacement. The physical dimensions of surviving specimens of this type vary according to standard hand-manufacture norms, typically exhibiting flan diameters between 29 and 33 millimeters and weights clustered broadly between 20 and 27 grams. These variations reflect manual blank weighing and alloy lot shifts rather than any intentional denominational subdivision.

Obverse Iconography and Imperial Presentation

The obverse of RIC III Marcus Aurelius 1171 presents a laureate head of Marcus Aurelius facing right, unadorned by drapery or cuirass. The portraiture is rendered in the characteristic mature Antonine baroque aesthetic, distinguished by deeply drilled curls in the emperor's hair and long, bifurcated beard. This sculptural treatment emphasizes both Stoic intellectual gravitas and imperial maturity. The laurel wreath tied at the nape of the neck serves as an overt symbol of military triumph and sovereign authority, terminating in two hanging ribbons (lemnisci) that rest across the rear base of the neck. Celators working on this issue produced slight stylistic nuances across distinct obverse dies, varying the treatment of individual facial contours, eyebrow projection, and wreath foliage density, while uniformly maintaining the recognizable physiognomy of the aging emperor.

Reverse Iconography: The Imagery of Aequitas

The reverse type features the allegorical personification of Aequitas, represented as a draped female figure standing facing left. In her lowered right hand she suspends a pair of balancing scales (libra), symbolizing impartial measurement, fairness in administrative taxation, and the uncorrupted integrity of official weights and measures. Resting along her left arm is a brimming cornucopiae, an emblem of agricultural fertility and economic prosperity flowing directly from just governance. Aequitas is draped in a classical stola and palla, with folds cut to suggest movement and three-dimensional depth. Flanking the lower fields to the left and right of the figure are the letters S and C (Senatus Consulto). The motif assured the populace and commercial communities that the central government remained committed to fair dealing, regular price stability, and reliable monetary value amid the severe logistical strains caused by ongoing border warfare and internal rebellion.

Inscriptions, Titulature, and Epigraphy

The obverse legend reads M ANTONINVS AVG GERM SARMATICVS, running clockwise along the inner beaded border. This epigraphic formula incorporates Marcus Aurelius's imperial name and praenomen alongside his formal victory cognomina: Germanicus, acquired in AD 172 following northern victories over Germanic coalitions, and Sarmaticus, assumed in the second half of AD 175 after campaigns across the middle Danube against the Iazyges. The reverse legend carries the continuous formula TR P XXX IMP VIII COS III, arranged around the upper perimeter and down the sides of the type. This sequence records the emperor's thirtieth tribunician renewal (Tribunicia Potestate XXX), his eighth imperial salutation (Imperator VIII), and his third consulship (Consul III). The bold characters S C in the field below confirm the constitutional tradition of striking base-metal coinages under formal senatorial decree.

Chronological Sequence and Related Typology

The chronological envelope of RIC III Marcus Aurelius 1171 is firmly fixed by its epigraphic titulature. The assumption of Marcus Aurelius's thirtieth tribunician power commenced around 10 December AD 175 and terminated on 9 December AD 176. His eighth imperial salutation occurred in late AD 175, connected with the collapse of the eastern usurpation of Avidius Cassius and subsequent settlements along the northern frontier. Consequently, this sestertius belongs strictly to the late AD 175 and AD 176 striking periods. The Aequitas reverse was struck in parallel with other allegorical themes from the same production period, including types celebrating Pax, Felicitas, and Victoria, as well as commemorative issues honoring the deified Faustina the Younger, who died in late AD 175. The presence of the title Sarmaticus distinguishes this type from earlier iterations of the Aequitas sestertius struck during his twenty-ninth tribunician year.

Circulation Patterns and Archaeological Context

Sestertii of Marcus Aurelius circulated broadly across the entire territory of the Roman Empire, although their primary physical recovery occurs in western military camps, provincial capitals, and along key supply arteries in Gaul, Britain, the Rhine frontier, and the Danubian limes. Due to their durable copper-alloy mass and significant value, sestertii of the late Antonine period often remained in active circulation for decades, frequently showing heavy surface wear, smoothing, and occasional countermarking during third-century fiscal reorganizations. Hoard evidence from the western provinces indicates that mid-to-late second century sestertii constituted the core volume of civic cash pools well into the Severan era. Losses of RIC III Marcus Aurelius 1171 in river deposits, urban destruction layers, and auxiliary fort vici illustrate their practical deployment in military payroll distributions and subsequent regional market transactions.
