Phokaia shared the electrum hekte series with Mytilene under a formal agreement — the two cities alternated issues, each identifiable by distinct obverse types, with Phokaia's pieces traditionally lacking the reverse incuse designs used elsewhere. The natural electrum used in these coins came from Lydian river sources, with a gold-to-silver ratio that varied enough between emissions to affect color noticeably. Bodenstedt's classification of this piece as Em. 98 places it in the later phase of the series, issued before the Phokaic mint was effectively shut down following the King's Peace of 387 BC, which curtailed the city's autonomy.
