EF, deeply toned, light scratch under tone on reverse. Perfectly centered on excellent metal. Ex Comte René Philipon Collection (1870-1936). Neapolis, which is well known for its apparently large issues of silver in the 5th-early 4th centuries BC, is relatively unknown outside of numismatics. Its exact location is unknown, though a city that has been under excavation near modern Polychronon may be Neapolis. The city was likely founded as a settlement by colonists from Mende in the 6th century BC. Like many of the other cities in the region, Neapolis supplied troops and ships to Xerxes during the Greco-Persian Wars, and afterward became a member of the Delian League. Its coinage consists of two large series of silver coins, both featuring the facing head of a gorgoneion on the obverse. The first series, with a simple quadripartite incuse reverse, began late in the Archaic period, circa 500 BC, and lasted until circa 480 BC. This is followed by a dual-sided coinage of drachms and hemidrachms featuring a female head on the reverse, which ran from the late 5th century BC until the early 4th century BC.

Gorgon′s head facing, with tongue protruding rev. Quadripartite incuse square. Neapolis ″new city″ was an ancient Greek city located in Edonis, a region of Thrace and later of Macedon. The site is located near modern Kavala. Neapolis was founded by colonists from Thasos, perhaps around the middle of the 7th century BC. Neapolis was a member of the Delian league and entered the Athenian tribute list at 454 BC first by toponym and by 443 BC by city-ethnic name. Recorded a total of fourteen times form 454 to 429 BC, it paid a tribute of 1,000 drachmas a year. It had independence from Thasos as dues of its customs were collected in its own harbour. At one point, property of Neapolitans in Thasos was confiscated by the oligarchs related to a situation from before 463 BC when the Thasian peraia was detached from Thasos. Despite the defection of Thasos from the Delian league in 411 BC, Neapolis remained loyal, causing the Neapolitan oligarchs to flee to Thasos and the confiscation of their property. Neapolis was besieged by the Thasians unsuccessfully, causing the Athenians to praise them for their loyalty and for participating in the siege of Thasos itself in 410 or 409 BC. Around 350 BC, Philip II of Macedon took Neapolis and used it as Philippi′s harbor. At the Battle of Philippi in 42 BC, the harbor was used as a base by the Republican leaders Brutus and Cassius. It kept its importance as a station on the Via Egnatia through the Imperial and early Christian periods. Paul landed here when he sailed from Troas to begin his missionary labors in Europe.

SNG ANS 405. Babelon, pl. 55. Rare. Extraordinary metal quality. Attractively toned. Extremely fine. Ex Peter Guber Collection. Neapolis was a colony of Thasos on the Thracian coast near the mineral-rich district of Mount Pangaion. The purpose of this foundation was to protect Thasian mining interests in the region. Not surprisingly, the design on the coinage of Neapolis also performs a protective function. The obverse device is the head of the gorgon Medusa, whose face was so hideous that anyone who looked directly at it would be turned to stone. In myth, the hero Perseus overcame this magic with the aid of Athena, who gave him a mirror and advised him to use it to see Medusa indirectly. Even after Perseus beheaded the gorgon, Medusa’s visage retained the power to petrify those who made the mistake of looking upon it. Thus her image on the coins of Neapolis was intended to ward off all intruders. The rather lumpy appearance of this stater is typical of the earliest coinage, as is the simple reverse. The recessed or incuse pattern on the reverse was caused by a special punch used to force the annealed metal of the flan into the obverse die. The use of a second die for the reverse, with its own artistic design, was a later development. Estimated Value: 7,500$.
