Didrachm

Kalymna — the island now known as Kalymnos — operated as an independent polis with its own mint during this period, though its output was modest compared to neighboring Rhodian issues that increasingly dominated Aegean commerce. The island's sponge-diving economy and strategic position between Kos and the Dodecanese gave it enough commercial activity to sustain a coinage, but the mint ran intermittently rather than continuously, which accounts for the relative scarcity of surviving examples across all types.

HGC 6, 1283 is among the scarcer Kalymnian didrachm references, with few specimens appearing in major auction records.
