Stater

Kyzikos dominated electrum coinage production in the fifth century BC to a degree that no other city in the Greek world matched — the city's staters circulated as a de facto international trading currency across the Black Sea, Aegean, and into Persia, accepted not by decree but by reputation alone. The Kyzikene stater effectively functioned as the hard currency of its era's long-distance commerce, with ancient sources recording prices quoted specifically in "Kyzikenes" rather than any civic standard.

The electrum itself was sourced from the Paktolos River region, and Kyzikos maintained strict weight discipline across centuries of production — a consistency that underpinned merchant trust far more than any political guarantee could.
