Hemihekte

Kyzikos was the dominant source of electrum coinage in the Greek world during the fifth century BC, producing a vast series of staters and fractions that circulated far beyond the Propontis as a trusted trade currency. The city's electrum was alloyed to a consistent standard, which gave Kyzikenian issues a commercial reliability that most civic coinages lacked. The hemihekte — one-twelfth of a stater — served the smallest high-value transactions in that system.

Von Fritze's corpus remains the authoritative reference, though the "cf." qualification here signals the type doesn't map cleanly onto a recorded die pairing.
