Chalkon

Sikyon occupied an unusual position among Peloponnesian poleis — prosperous enough to maintain an active bronze coinage but politically squeezed between Corinth and the Achaean cities throughout the fourth century. The city's bronze issues of this period are frequently attributed to the reforms following Euphron's democratic coup around 367 BC, after which Sikyon briefly aligned with Thebes before reverting to oligarchic control. Administrative instability across that span likely interrupted production, which may account for the relatively limited die pool known for this denomination.
