Tetrobol - Mithridates VI Phanagoria

Historical Context: This Tetrobol from Phanagoria, issued 109-100 BC, marks a critical period in Mithridates VI Eupator's ascendancy. During this decade, Mithridates aggressively consolidated control over the Bosporan Kingdom, incorporating strategic cities like Phanagoria into his expanding Black Sea empire. This coinage facilitated commerce and served as potent propaganda, legitimizing his authority and showcasing his dominion over this vital Hellenistic region prior to his epic confrontations with Rome.

Artistry: The coin's design follows established Hellenistic artistic traditions. The obverse typically presents a finely executed, idealized portrait of Mithridates VI, often rendered with heroic or divine attributes to underscore his regal power. The reverse commonly features an animal motif, such as a grazing stag, a symbol closely associated with Mithridates, accompanied by a legend identifying the ruler. The engraving style reflects the general Hellenistic aesthetic and distinct craftsmanship of Bosporan mints.

Technical/Grading: Struck in silver, this tetrobol measures 14 millimeters and weighs 2.31 grams. For high-grade examples, a strong, centered strike is paramount, ensuring full detail on Mithridates’ portrait—especially the hair, diadem, and facial features—and the intricate reverse design. Given the small flan, minor off-centering or areas of strike weakness, particularly at the periphery, are frequently observed. Silver quality generally ensures good preservation of surface details from well-prepared dies.
