Semis Achilles left, Corinthian helmet, horse left, ΝΙΚΟΜΑΧΟΥ

Historical Context: This bronze Semis, issued by the Koinon of Thessaly between 117-138 CE, situates it firmly within the reign of Emperor Hadrian. Hadrian, a known philhellene, encouraged local civic autonomy and cultural expression, facilitating such regional coinages. The Koinon, a federation of Thessalian cities, leveraged this period to issue bronzes, often for local games or festivals. The choice of Achilles, a hero deeply rooted in Thessalian mythology, underscores a deliberate connection to local identity and heritage under Roman oversight.

Artistry: The coin's design reflects the Roman provincial style, blending Hellenistic artistic traditions with imperial influence. While the engraver is anonymous, the name ΝΙΚΟΜΑΧΟΥ on the reverse likely identifies a local magistrate overseeing the issue. The obverse masterfully depicts Achilles, facing left, adorned with a distinctive Corinthian helmet, a classic Greek icon. The reverse features a horse, a symbol historically associated with Thessaly's renowned cavalry, moving left, accompanied by the magistrate's name. This iconography celebrates Thessalian heritage.

Technical/Grading: Weighing 2.54 grams and measuring 16 millimeters, this Semis is a small-denomination bronze. For optimal grading, collectors seek a strong strike on Achilles' Corinthian helmet and facial features, along with clear details on the horse's mane and musculature. Provincial bronze coinage often exhibits variability; thus, a well-centered strike with minimal die wear and a fully legible ΝΙΚΟΜΑΧΟΥ inscription would be highly prized. Flan irregularities or slight off-centering are common for issues of this period.
