The Persians adopted the Lydian tradition of minting coins following their conquer of Lydia in 547 BCE.
The daric was a golden coin used in the Persian Empire, which is thought to have been named after Persian king Darius I (521-486 BCE). The production of these coins continued after the death of Darius, up until Alexander the Great’s conquest of Persia during the 4th century BCE. Proceeding this conquest we see the use of the double daric, an innovation of Alexander.
