Æ15 ZA

Zacynthus, the westernmost of the Ionian Islands, maintained its own civic coinage throughout much of the Classical and Hellenistic periods despite shifting between Athenian, Spartan, and eventually Macedonian spheres of influence. The island's mint was notably active during the Peloponnesian War era, when Zacynthus aligned with Athens — a loyalty that brought Spartan siege attempts and the kind of political instability that typically disrupts coin production but here appears to have sustained it.

The five-century span assigned to this type reflects the difficulty of attributing undated Achaean bronzes with precision rather than any confirmed continuous issue.
