Gold darics and silver sigloi were introduced by Darius I during the late 6th century, as the empire’s bimetallic monetary standard. This revolutionary universal-coinage mobilised a regularised tax system, and engendered greater economic activity within the empire. Their easily-transportable nature enabled Darius to concentrate the empire’s tax-acquired wealth where he chose, and made private transactions more convenient. This efficient monetary-system remained in use until Alexander the Great’s invasion (330 BC).
