Achaemenid coinage

The Achaemenid Empire issued coins from 520 BC–450 BC to 330 BC. The Persian daric was the first gold coin which, along with a similar silver coin, the siglos (from Ancient Greek: σίγλος, Hebrew: שֶׁקֶל, shékel) represented the first bimetallic monetary standard. It seems that before the Persians issued their own coinage, a continuation of Lydian coinage under Persian rule is likely. Achaemenid coinage includes the official imperial issues (Darics and Sigloi), as well as coins issued by the Achaemenid provincial governors (satraps), such as those stationed in Asia Minor.
