Tetrobol

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.
