Obol

Phokaia's coinage was among the earliest struck in the Greek world, and the city's minters worked in an unusual tradition — electrum fractions dominated local production for generations before silver issues like this obol appeared. The switch reflects either shifting trade demands or metal availability pressures as Persian control over Ionia tightened following the failed Ionian Revolt of 499–494 BC, which devastated the region's economy and civic infrastructure.

The SNG von Aulock reference range spanning three catalog numbers suggests minor die variations across the archaic series rather than a single unified type.
