Likely used to pay mercenaries, these fifth-century B.C. coins offer significant historical insights into Persian currency and military operations. Led by Professor Christopher Ratté, the discovery sheds new light on the Persian Empire’s influence and the timeline of gold coinage. This rare find enhances our understanding of ancient Greek and Persian interactions.
