Hekte

Kyzikos dominated electrum coinage production in the eastern Aegean during the sixth and fifth centuries, and its hektai functioned as the principal trade currency across a vast commercial network stretching from the Black Sea grain ports to the markets of mainland Greece. The city's electrum was alloyed to a consistent standard that merchants recognized and trusted — a monetary reliability that outlasted most contemporary issuers by generations.

Von Fritze's classification remains the standard reference for the series, though individual dies show considerable variation in the natural gold-to-silver ratio of the raw electrum, reflecting different ore batches from the Propontis region.
