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.
Australian one-cent coin The first issue (1966) was produced by three mints: 146.5 million were minted at the Royal Australian Mint in Canberra, with 239 million at the Melbourne Mint and 26.6 million at the Perth Mint. With the exception of 1966 and 1981, all other one-cent coins have been produced at the Canberra mint. In 1981, 40.3 million were struck at the British Royal Mint in Llantrisant, Wales, as well as 183.6 million in Canberra. The only year when it was not minted during its years in general circulation was 1986. It was last minted in 1990.[4]
