Stater

Kyzikos dominated electrum coinage production in the Aegean for roughly two centuries, and the city's staters functioned as a de facto international trade currency across Greek, Persian, and Thracian markets simultaneously. The electrum alloy used was not standardized — Kyzikene staters vary measurably in gold-to-silver ratio across the series, suggesting the mint drew on multiple metal sources rather than maintaining a fixed recipe.

The tuna fish incorporated into virtually every reverse type was not decorative convention but a civic identifier, the tunny being central to Kyzikos's economy through Black Sea fishing rights. Production ceased abruptly after Alexander's conquest of the Propontis region in 334–333 BC rendered the city's monetary independence obsolete.
