Dichalkon

Gyrton was a minor Thessalian city in the Peneios river valley, and its independent bronze coinage is among the scarcest from the region. The BCD collection — assembled by a single collector whose Thessalian holdings remain the definitive private reference for the series — treated Gyrton's bronzes as significant precisely because so few poleis of comparable size struck their own civic issues during this period.

Rogers 229 represents one of a handful of recognized die pairings for this type. The city fades from the numismatic record entirely by the late fourth century, likely absorbed into the Macedonian administrative orbit following Philip II's consolidation of Thessaly after 344 BC.
