Sabina Silver Denarius, RIC II, Part 3 (second edition) Hadrian 2550

Monetary Context and Denominational Function

During the reign of Hadrian (AD 117 to 138), the silver denarius was the primary silver denomination of the Roman Empire, mediating between large-scale financial disbursements in gold aurei and local retail commerce conducted in bronze sestertii, dupondii, and asses. The denarius of the 130s AD adhered to the metallurgical and metrological benchmarks established during Trajan's currency reform around AD 107. Denarii under Hadrian typically operated on a theoretical target weight near 3.20 to 3.35 grams, with an alloy fineness fluctuating around 80 to 85 percent silver balance copper. While civic populations throughout the provinces also encountered regional cistophori in Asia Minor or provincial drachms in Syria and Egypt, imperial denarii minted in Rome held universal legal tender and moved freely across the frontiers, legionary camps, and major urban trade hubs. The striking of coinage for the imperial women served an essential political and ideological purpose within this monetary framework. Coinage bearing the image of Sabina affirmed the dynastic continuity, stability, and legitimacy of the Ulpian-Aelian family line, reassuring senators, soldiers, and citizens that the imperial house enjoyed divine favour and concord.

Mint Organization and Production Techniques

The entire regular emission of RIC II, Part 3 (second edition) Hadrian 2550 was struck at the sole imperial mint located in Rome. By the late reign of Hadrian, the Rome mint was a highly structured bureaucratic and artisanal enterprise, divided into designated workshops or officinae capable of synchronizing simultaneous production runs of gold, silver, and bronze. Denarii blanks were prepared by casting uniform flans in clay or stone molds, which were subsequently weighed, trimmed, and treated before hot strike. Die-engravers at Rome achieved exceptional plastic quality during this epoch, often dubbed the Hadrianic classicism, marked by refined Hellenic naturalism and balanced geometric compositions. Obverse portrait dies of Sabina were created with high relief, necessitating sturdy bronze or iron dies that were paired with reverse dies and hammered manually. The die axis for this issue follows the standard Roman imperial practice of regular vertical orientation, most commonly aligned at approximately 6 o'clock or 12 o'clock, reflecting careful placement within the striking tongs.

Obverse Iconography and Portraiture

The obverse of RIC II, Part 3 (second edition) Hadrian 2550 displays the right-facing bust of Vibia Sabina, draped at the shoulders and wearing a stephane or diadem. The defining typological feature of this specific catalogue entry is her hairstyle: the hair is parted and drawn back smoothly over the ears, secured beneath a crescent-shaped diadem or stephane, and gathered into a long plait or queue that hangs down along the nape of the neck. This distinctive coiffure represents the final major hairstyle developed for Sabina before her death around late AD 136 or early AD 137. It departed sharply from the towering, curled headpieces of the Flavian and Trajanic matrons, presenting a dignified, classical simplicity that mirrored Hadrian's philhellenic aesthetic tastes. Engravers carefully rendered the folds of the mantle over her breast and shoulder, lending a sculpted appearance that mirrored contemporary state marble statuary and elite imperial portrait busts produced in Roman workshops.

Reverse Iconography: Juno Regina

The reverse iconography depicts Juno Regina standing turned toward the left, draped in long stola and peplos, embodying her role as the supreme protector of Rome and the patron deity of marriage and imperial women. In her outstretched right hand, the goddess holds a patera, a shallow sacrificial libation bowl used to pour liquid offerings upon altars, symbolizing piety and religious dutifulness. In her left hand, Juno holds a tall sceptre, the age-old attribute of sovereignty and divine rule. Juno Regina, as the foremost female divinity of the Capitoline Triad alongside Jupiter Optimus Maximus and Minerva, served as the primary celestial counterpart to the living empress. By pairing Sabina with Juno on this denarius, the mint artisans directly linked the domestic virtues and exalted imperial rank of the Augusta to the queen of heaven, presenting Sabina as the earthly guardian of traditional Roman family ethics and public harmony.

Epigraphy and Legends

The epigraphic layout of RIC II, Part 3 (second edition) Hadrian 2550 is characterized by concise, regal inscriptions rendered in refined classical Roman capitals. The obverse legend reads SABINA AVGVSTA, positioned clockwise around the periphery of the flan starting from the lower left. This concise formulation was introduced after her initial titular expansions and omits patronymic or marital references, such as HADRIANI AVG P P, relying solely on her personal name and supreme female title to establish identity and authority. The reverse legend carries the dative dedication IVNONI REGINAE, translating to 'To Juno the Queen'. The use of the dative case is customary in Roman votive coinage, signalling that the coin design acts as a commemorative dedication or sacrifice to the divinity on behalf of, or in alignment with, the imperial Augusta.

Typological Classification and Chronological Placement

Within the reconstructed chronological framework established in the revised second edition of Roman Imperial Coinage (RIC II, Part 3), this denarius is dated to the penultimate phase of Hadrian's principate, between approximately AD 133 and AD 135. Sabina received the title Augusta alongside Hadrian's assumption of the title Pater Patriae around AD 128, but her early coinage employed differing titulature and more elaborate coiffures with high diadem crests. The introduction of the simplified legend SABINA AVGVSTA in combination with the plait or queue hairstyle denotes the mature phase of her mint output. RIC 2550 is catalogued specifically for the reverse featuring Juno Regina standing left holding a patera and sceptre; it stands distinct from contemporaneous denarii bearing IVNONI REGINAE where Juno is accompanied by a sacred peacock at her feet (such as RIC 2551) or seated upon a throne. The narrow production window places this issue right in the final years preceding Sabina's death and her subsequent consecration as Diva Sabina in AD 136 or 137.

Circulation, Hoard Evidence, and Survival

Upon leaving the Rome mint, denarii of Sabina circulated across the provincial territories of the empire alongside the broader issues of Hadrian and earlier Antonine or Flavian silver. Hoard evidence from western Europe, notably the British, Gallic, and Danubian frontiers, reveals that denarii of Sabina enjoyed prolonged monetary lives, frequently remaining in active circulation well into the Severan era until the massive debasements of the third century AD prompted systematic withdrawal and melting. While not struck in the immense quantities seen in Hadrian's own military or provincial travel series, the IVNONI REGINAE types represent an appreciable fraction of Sabina's late silver issues. Surviving specimens across major institutional and private collections show variable states of wear, often exhibiting central die wear or peripheral clipping consistent with prolonged commercial velocity over multiple decades.
