Tetradrachm

Rhodes operated as an independent issuing authority following the synoikism of 408 BC, when the three older city-states of Ialysos, Kamiros, and Lindos merged to found a single polis. The tetradrachm series of the early fourth century falls within a period of Rhodian commercial dominance across the eastern Aegean, where the island's merchant fleet made its coinage a trusted medium well beyond local exchange. The Hecatomnus reference places this piece within a tightly defined die study, suggesting the type circulated into Carian trade networks under the Hecatomnid dynasty's sphere of influence.
