in 7th century bce which city made the first ever coin
Ancient Greek coinage The first known coins were issued in either Lydia or Ionia in Asia Minor at some time before 600 BC, either by the non-Greek Lydians for their own use or perhaps because Greek mercenaries wanted to be paid in precious metal at the conclusion of their time of service, and wanted to have their payments marked in a way that would authenticate them. These coins were made of electrum, an alloy of gold and silver that was highly prized and abundant in that area. By the middle of the 6th century BC, technology had advanced, making the production of pure gold and silver coins simpler. Accordingly, King Croesus introduced a double metal standard that allowed for coins of pure gold and pure silver to be struck and traded in the marketplace.
