Gold was used in commerce (beside other precious metals) in the Ancient Near East since the Bronze Age, but coins originated much later, during the 6th century BC, in Anatolia.
King Croesus of Lydia is usually credited with the invention, although the Parian Chronicle mentions Pheidon of Argos as a contender. In 546 BC, Croesus was captured by the Persians, who adopted gold as the main metal for their coins.
