AKARNANIA, Stratos. Circa 350-300 BC. Dichalkon (Bronze, 18mm, 6.30 g 3). Head of the nymph Kallirhoe to right. Rev. ΣTPATIΩN Horned head of river-god Acheloos to right. BCD 362. Imhoof-Blumer, Die Münzen Akarnaniens, 163, 9. Very rare. Obverse struck from a worn die and flan fault on both sides, otherwise, very fine.

The flan fault must result from a technical problem during the production of the blanks, see the BCD coin that shows a similar defect on the obverse.
