Lot 293: Kings of Pontos. Mithradates VI Eupator. Tetradrachm, circa 120-63 BC., Pergamon mint. Dated month 12, year 223 BE (September 74 BC). Superb EF. Undoubtedly the finest specimen known. From the Jonathan P. Rosen Collection. Estimated at $30,000.

Masterpiece of Hellenistic Art – Ex Sheikh Saud Al-Thani and JDL Collections

Mithradates is the Hellenistic monarch par excellence, his career driven by megalomaniacal ambitions leading to murderous assaults upon family and followers and disastrous foreign adventures against superior forces. His idealized portraiture attempts to mimic the gods with its bold staring gaze and unruly, free-flowing hair, but at its most extreme is a personification of hysteria in its Dionysiac sense. The wreath of ivy on the reverse reinforces Mithradates’ link with the god as well as making a connection with the cistaphoric coinage that circulated in the area. The stag probably represents the civic center of Ephesos and the mintmark is of Pergamon, all part of the new Pontic kingdom, symbolized by the star and crescent. His empire collapsed before the armies of Sulla and Lucullus, and Mithradates ended his own life in exile in the far region of the Crimea, pursued to the end by vengeful Romans and family.

Lot 775: Commodus. AD 177-192. Bimetallic Medallion, Rome mint. Struck AD 191-192. Near EF. Very rare. Estimated at $20,000.

Impressive Commodus Medallion

This remarkable obverse has been the cause of debate. The pelta, a distinctively Amazonian shield, has long led some to identify the female figure as Marcia, Commodus’ concubine and trusted companion whom, we are told, the emperor loved to see dressed as an Amazon (SHA, Com. 12.1). The idea that Marcia – who was involved in the assassination of Commodus – should appear on a medallion of the emperor struck the year of his death has incredible historical and emotional appeal, and prominent 20th century scholars like Harold Mattingly and Jocelyn Toynbee accepted the identification. Others have discounted this fantastic claim, questioning the likelihood of a mistress with no official role or titles making an appearance on medallions.

Dressel has argued that the pelta could be an attribute of Commodus rather than the female figure. “Amazonius” was one of the many titles the crazed emperor bestowed on himself late in his reign (when Commodus renamed the months of the year, March became “Amazonius”). A similar obverse type also from AD 192 has jugate busts of Commodus and a female figure wearing a helmet and cuirass, normally identified as Minerva. It is possible that the current obverse depicts Roma, as there is some evidence that Roma and Minerva were favored deities of the emperor.

Lot 906: Licinia Eudoxia. Augusta, circa AD 439-490. Solidus. Commemorative issue. Ravenna mint. Struck circa AD 439 or 444-445. Superb EF. One of the finest known. From the Provence Collection. Estimated at $100,000.

Exceptional Licinia Eudoxia

Licinia Eudoxia was the only surviving child of the Eastern Roman Emperor Theodosius II, and in 424 AD, at the age of two, was betrothed to her four-year-old cousin, the future Emperor of the Western Roman Empire Valentinian III, in order to reunify the two halves of the Roman world. Their marriage produced two daughters, but was abruptly terminated when Valentinian was killed by two Scythians, Optelas and Thraustelas, at the behest of the usurper Petronius Maximus. After buying off the military and palace officials, Maximus cemented his claim to the throne by forcibly marrying Eudoxia only a few days after her husband’s murder. At least one historian theorized that Maximus’ marriage to Eudoxia was motivated by revenge against the late Valentinian in return for the Emperor’s rape of Maximus’ first wife. Maximus also married his son Palladius to Eudoxia and Valentinian’s daughter Eudocia, thereby severing her engagement to Huneric, the son of the Vandal king Gaiseric.

Deeply unhappy, Eudoxia somehow managed to contact Gaiseric to beseech him to depose Maximus. The Vandals successfully besieged Rome and carried Eudoxia off to Carthage, along with her daughters; Maximus was assassinated by members of the Imperial household during the siege and his body thrown into the Tiber. In 462 AD, after seven years in Carthage, Eudoxia and her daughter Placidia were ransomed by Leo I and moved to Constantinople, while Eudocia remained in Carthage and married Huneric as her parents had originally intended. The rest of Eudoxia’s life passed unrecorded; even her exact date of death is unknown.

Lot 1025: Carolingians. Charlemagne (Charles the Great). As Charles I, King of the Franks, 768-814. Tremissis, Lucca mint. Struck after the defeat of Desiderius in 774. A coin of great historical and iconographic interest. A couple of hairline flan cracks. EF. Extremely rare. From the Richard A. Jourdan Collection. Estimated at $100,000.

Charlemagne Portrait in Gold –  Struck at Lucca After the Defeat of Desiderius in 774

The only gold coin to bear a portrait of Charlemagne, one of the most important figures in world history. His deeds shape Europe to this day.
Following Charlemagne’s conquest of the Lombardic kingdom in 774 AD, a short-lived issue of gold tremisses was struck at a range of mints across northern Italy in his name. These rare coins are all of the same star/cross potent type of the defeated Desiderius, except for an extremely rare issue at Lucca that remarkably depicts the King of the Franks on the reverse. Rossini records only six specimens of the portrait issue, four of which are damaged and incomplete. Only one other example has previously appeared at auction. That coin, from the Adams collection (Triton XIX, lot 2207), realized $180,000 in 2016.

Lot 1346: Hanover. William IV. 1830-1837. Pattern Five Pounds. London mint. Dated 1831. In NGC encapsulation 4747472-001, graded PF 62 Ultra Cameo. A magnificent coin. Extremely rare. From the G.W.K. Roberts Collection. Estimated at $200,000.

William IV Pattern Five Pounds – From the Murdoch and Copp Collections

Struck to the exact weight of five Sovereigns from the dies used for the proof Crown of 1831, this pattern Five Pounds of William IV is one of the great rarities of the British series. For any collector attempting to form a complete collection of Five Guinea and Five Pound pieces by monarch, from Charles II to Elizabeth II, the Five Pounds of William IV is by far the most challenging coin to obtain.

The specimen offered here is in superb condition and has not been on the market for over 40 years. It once graced the celebrated cabinet of John Gloag Murdoch, one of the finest collections of British coins ever assembled. Murdoch acquired the coin in 1887 from Alfred Evelyn Copp, the Treasurer of the Numismatic Society of London and distinguished collector of rarities.
