Hemiobol

Atarneos — a small coastal settlement in the Troad — operated a mint only briefly, and its silver fractions are among the scarcest archaic Greek issues by any polis in the region. The city later became notorious as the base of Hermeias, the former slave who rose to become its ruler and whose philosophical connections to Aristotle drew Macedonian political interest in the 340s BC, but this coin predates all of that by half a century.
