Tetradrachm

Syracuse dominated the coinage of fifth-century Sicily, and the tetradrachm was the engine of that economy — used to pay mercenaries, finance naval operations, and settle debts with Carthaginian traders pressing from the west. The decade bracketing 450–440 BC falls within the so-called "fine style" transitional period, after the archaic conventions had loosened but before the celebrated die-engravers like Kimon and Euainetos transformed the series into something approaching sculptural showmanship.

The Boehringer sequence places this emission within a tightly documented die study; cross-referencing with the ANS and McClean concordances allows reasonably precise die attribution. Boehringer 582 specifically.
