Ex BCD Collection (Triton IX, 10 January 2006), lot 417; Thessaly, c. 1966 hoard (IGCH 45).

This charming coin was part of IGCH 45 which also included a Phocis hemidrachm (Williams, Silver Coinage of the Phokians [London, 1972], 259) in pristine condition. Williams considers 418 BC as the most likely date for the issue of the hemidrachm (Williams p. 40) and this, given that the stater is in a category of coins which were not in daily use and therefore would wear at a slow rate, would agree with the lower end of the chronology bracket suggested above for the Theban piece.
