Dichalkon

Thelpusa was a minor Arcadian polis on the Ladon River, absorbed into the newly founded Megalopolis around 371–368 BC when Epaminondas and the Arcadian League forcibly synoikized much of the region. That this issue exists at all suggests either minting before the synoikism was fully enforced or a brief reassertion of civic identity afterward — the chronology remains genuinely unresolved among specialists. The BCD collection contained only a handful of Thelpusan bronzes, reflecting how little coinage the city managed before losing autonomous status.
