Reverse description	Coiled serpent of Asklepios depicted upright within a shallow incuse square, the body rendered in tight coils with the head raised to the right. The magistrate names are inscribed in Greek letters flanking the serpent: ΝΙΚΟΜH to the left and ΘΕΥΦΑΜΙ to the right, with ΚΩΙ appearing below, identifying the issuing city of Kos. The incuse square frame is a hallmark of Koan silver coinage of this period. The overall composition is bold and well-centred within the available flan.

Additional information	Kos maintained a productive civic mint through much of the Hellenistic period, its output shaped in part by the island's unusual political position — nominally autonomous yet deeply embedded in the orbit of Rhodes, whose commercial reach dominated the southeastern Aegean. This tetrobol falls within a period when Rhodian influence over neighboring island mints was at its height, and Koan coinage from these decades often circulated as much through mercantile networks as through local exchange. HGC 6, 1324 represents a scarce subtype within the broader Koan silver series.
