Trajan
Trajan, born Marcus Ulpius Traianus in Hispania Baetica, served as Roman emperor from 98 AD until his death in 117 AD. Remembered as one of the Five Good Emperors, he was officially acclaimed by the Roman Senate as Optimus Princeps, or 'best ruler.' Renowned as a brilliant military commander, Trajan expanded the Roman Empire to its greatest territorial extent through the conquest of Dacia, the annexation of Nabataea as Arabia Petraea, and sweeping campaigns against the Parthian Empire in Armenia and Mesopotamia. Beyond his martial achievements, Trajan was celebrated for civic philanthropy, extensive public works throughout Italy and the provinces, and respectful cooperation with the Senate.

- RIC II Trajan 127
Monetary Context and Historical Background
The denarii of Trajan produced under his fifth consulship belong to one of the most prolific and economically consequential periods in Roman imperial minting history. Following his victory in the First Dacian War (AD 101 to 102) and his triumph celebrated late in AD 102, Trajan held the consulship for the fifth time beginning in January AD 103. He did not assume a sixth consulship until AD 112, leaving an extensive chronological window during which the formula COS V defined the reverses of the imperial mint at Rome. During this protracted period, the Roman fiscal landscape underwent substantial structural shifts. Massive state expenditure was required to finance the renewal of hostilities in Dacia between AD 105 and 106, which culminated in the annexation of the province and the acquisition of vast Dacian gold and silver treasures. This immense influx of precious metal allowed the Roman state under Trajan to retire older, worn Republican and early Julio-Claudian silver denarii from active circulation. As modern metallurgical studies have demonstrated, Trajan enacted a managed reduction in the silver fineness of the denarius around AD 107, stabilizing the standard at roughly 89 to 90 percent silver. RIC II Trajan 127 belongs directly to this dynamic monetary horizon, functioning both as standard military and administrative payment and as a mass-circulated instrument of state ideology.
Mint Organization and Production Standards
The entire regular production of RIC II Trajan 127 is attributed exclusively to the imperial mint situated in the city of Rome. During Trajan's reign, the Rome mint operated under a highly centralized administrative structure overseen by the equestrian procurator monetae, functioning through distinct workshops or officinae to execute large-scale, coordinated coin series in gold, silver, and bronze. Trajanic denarii of this type were struck on cast silver flans prepared by striking workers using carefully engraved iron dies. The theoretical weight standard for the denarius at this time aligned with approximately 1/96 of a Roman pound (libra), yielding an intended normal weight around 3.25 to 3.40 grams, though normal metallurgical tolerance created a broader weight spread across surviving populations. Die alignment at the Rome mint was generally oriented along an approximate six o'clock axis, though slight mechanical variances occurred routinely during manual hammer striking. Die analysis of the COS V denarii demonstrates a high volume of output, with multiple obverse and reverse dies cut by skilled die-sinkers exhibiting consistent stylistic norms and high sculptural relief.
Obverse Iconography and Variations
The obverse of RIC II Trajan 127 depicts the mature portrait of Trajan facing right. In accordance with the realistic portrait tradition developed after the Flavian era and refined in Trajan's initial quinquennium, the emperor is portrayed with a pronounced linear profile, a straight nose, a low, clean brow, and his characteristic forward-combed hair cut straight across the forehead. The principal variation attested for this specific catalogue entry involves the treatment of the bust. The primary form features a laureate head or bare neck terminating naturally at the truncation, but specimens are frequently documented displaying light drapery on the far left shoulder, or occasionally full drapery across the shoulders. The laurel wreath is bound at the rear of the head with two distinct ribbon ties (taeniae) that fall toward the nape of the neck. Trajan's expression conveys military resolve and gravitas, embodying the imperial persona of a vigorous commander and civic protector without the excessive dynastic stylization common under the earlier Julio-Claudians.
Reverse Iconography and Symbolism
The reverse of RIC II Trajan 127 is devoted entirely to the personification of Spes, the ancient Roman deity of hope and future promise. She is depicted draped in an archaizing, long chiton, advancing gracefully toward the left. In her extended right hand, Spes holds aloft a small flower bud, commonly interpreted as a lotus blossom or pomegranate flower, signifying the tender unfolding of life and seasonal renewal. With her left hand, she gently catches and raises the pleats of her skirt as she strides forward. In Roman imperial iconology, Spes held deep associations with youth, dynastic succession, and auspicious beginnings. Under the Julio-Claudians and Flavians, Spes was frequently invoked to herald young heirs or celebrate anniversaries. Under Trajan, who held no biological son and was cautious regarding public statements on formal succession in the early 100s AD, the revival of Spes conveyed a broader political meaning: the renewed vigor and optimistic future of the Roman commonwealth (Spes Publica) achieved under an ideal ruler. Her rhythmic gait and delicate attribute provided an aesthetic balance to the heavily militarized themes of the contemporaneous Dacian triumph series.
Inscriptions and Epigraphic Analysis
The legends on both faces of RIC II Trajan 127 are composed in standard Roman imperial capitals, executed with fine serifs and neat spacing. The obverse legend reads IMP TRAIANO AVG GER DAC P M TR P. This formula begins in the dative case (Imp[eratori] Traiano Aug[usto]), a grammatical shift initiated under Trajan to present the coinage as an honorary dedication from the Roman state to the ruler. The imperial titles include Ger[manicus], awarded in AD 97 during his adoptive period under Nerva, and Dac[icus], assumed late in AD 102 following his initial campaigns across the Danube. These titles are complemented by P[ontifici] M[aximo] (high priest) and Tr[ibunicia] P[otestate] (holder of tribunician power). The reverse legend reads COS V P P S P Q R OPTIMO PRINC, which translates epigraphically as Cos (Consuli) V (Quintum), P(atri) P(atriae), S(enatus) P(opulus) Q(ue) R(omanus), Optimo Princ(ipi). This legend continues the dative construction initiated on the obverse, declaring that the Senate and the Roman People dedicate the issue to the 'Best Prince' (Optimus Princeps), an appellation that had been unofficially popular since the beginning of his reign and was increasingly prominent in official propaganda prior to its formal senatorial conferral as an official cognomen in AD 114. The inclusion of COS V firmly links the issue to the long consular tenure beginning in AD 103.
Typology and Internal Chronology
In the foundational arrangement of the Roman Imperial Coinage (RIC), Harold Mattingly placed type 127 among the silver denarii bearing the fifth consular iteration, spanning AD 103 to 111. Within this framework, RIC 127 is distinguished from neighboring types by its specific pairing of the advancing Spes reverse with the abbreviated obverse legend lacking later honorific expansions, such as the full nominative title OPTIMO AVG GER DAC utilized from AD 112 onward. More recent modern research, particularly the monumental corpus of Bernhard Woytek (Moneta Imperii Romani 14), has refined the dating of the COS V coinage through meticulous die linkage, bust typology, and portrait evolution. Woytek categorizes the Spes series within Trajan's major middle-reign emissions, placing the production of this reverse type predominantly between AD 103 and 107. This chronological subdivision coincides with the massive reminting programs immediately preceding and accompanying the culmination of the Second Dacian War, prior to the adoption of expanded titles in the later stages of the fifth consulship.
Circulation, Hoard Evidence, and Monetary Impact
Denarii of the RIC 127 type circulated extensively throughout the Roman Empire, as evidenced by their recurring presence in major imperial coin hoards across Britain, Gaul, the Rhine-Danube frontier zones, and the Mediterranean provinces. Because Trajan recalled older, pre-Neronian silver around AD 107, his newly struck COS V denarii quickly formed the bedrock of the Western provincial currency supply for subsequent decades. Hoard analyses demonstrate that these denarii possessed remarkable longevity. They circulated continuously not only through the remainder of Trajan's reign but also under Hadrian, the Antonines, and even into the Severan era, where they frequently appear in hoards terminated by the inflationary debasements of the third century AD. Due to their solid silver standard relative to the increasingly degraded debased issues of the third century, these coins were heavily hoarded and often survived in significant quantities, bearing varied degrees of honest circulation wear from decades of market transactions.
