Watch List notes:

Sicily, Selinos. late 5th century B.C. AR tetradrachm (26.2 mm, 17.04 g, 3 h). struck ca. 417 or 413 B.C.

This issue commemorates an important military victory, but which battle isn't entirely certain. It most likely commemorates either Selinos' victory over Segesta in 417 B.C. or Syracuse's victory over Athens in 413 B.C. in which Selinos sided with Syracuse.A nicer example sold in Triton X for $26,000.
