Hemistater

The earliest electrum coinages from western Anatolia — the Ionian and Lydian issues of the late seventh century — remain among the most debated in numismatics. Attribution is contested precisely because the earliest minting was likely shared infrastructure: private merchants, temples, and nascent civic authorities all had access to electrum from the Pactolus river valley, and no single issuing body held a monopoly. The hemistater denomination itself implies a larger stater already in circulation, suggesting this piece entered a system already establishing weight standards.

Natural Lydian electrum varied significantly in gold-to-silver ratio, typically between 45% and 55% gold.
