Tetartemorion

Kyme, the principal Aeolian city on the western coast of Asia Minor, issued these fractional silvers during a period when even the smallest commercial transactions required a physical medium of exchange. At 0.22 g, the tetartemorion represented one-quarter of an obol — itself already a minor fraction — placing it among the smallest denominations struck in the ancient Greek world. Several Aeolian mints produced coins at this scale, but Kyme's issues are distinguished by consistent fabric and a reasonably stable weight standard across the series.
