Dichalkon

Atrax was a minor Thessalian polis in the Perrhaebian borderlands, and its independent bronze coinage is sparse enough that the BCD collection represented one of the most concentrated assemblages of its civic issues ever brought together at auction. The dichalkon denomination itself reflects the fractional bronze systems that Thessalian cities adopted unevenly during the fourth century, often tied more to local market needs than to any regional monetary coordination.

The BCD Thessaly I sale in 2002 remains the definitive reference point for attributing these pieces.
