Obol - Darayan I Curved brim

Darius (Darayan) I of Persis ruled a client kingdom under Seleucid suzerainty in the region of Fars, the Persian heartland. These tiny fractional silver pieces were struck at a time when Persis maintained a carefully guarded local autonomy — issuing its own coinage while the Seleucid empire fractured under pressure from the Parthians to the east. The curved-brim variety is distinguished from related issues by die typology catalogued by Haebler and refined by Alram, whose numbering system remains the field standard for Persis coinage.
