Stater

Kyzikos held a near-monopoly on electrum coinage in the Greek world for roughly two centuries, and its staters circulated far beyond Mysia — found in hoards from the Black Sea coast to the Aegean and into Thrace. The city's position on the Propontis made it the dominant transit point for grain shipments from the Pontic region, and the staters functioned as a trusted mercantile currency across that entire network. Athenian records mention Kyzikene staters by name as acceptable payment in certain commercial contracts, a rare distinction for a non-Athenian issue.

Each obverse type is unique — the series runs to hundreds of distinct designs, changed with deliberate frequency, likely as an anti-counterfeiting measure given how widely the coins traveled.
