The Decimal coinage system (dollars and cents) was introduced to Australian on 14 February 1966. At the time 6 coins were issued, the 1 cent, 2 cent, 5 cent, 10 cent, 20 cent, and the short-lived round 50 cent coin. All the coins bore the Arnold Machin portrait of Queen Elizabeth II and reverse designs sculpted by Stuart Devlin. Because of the need for sufficient coinage for the changeover to the decimal system in 1966 coins were minted at the Royal Australian Mint in Canberra, and the Royal Mint branches in Melbourne, Perth, and London. Only the round 50 cent coin was solely minted in Australia.
