History: “The 20 cent coin was first introduced with decimalisation on 14 February 1966. The original reverse design remained unchanged until 1995. This denomination has since been used infrequently for commemorative designs.
All of the first issue of 20 cent coins in 1966 was produced at the Royal Mint, London. The Royal Australian Mint did not commence 20 cent coin production until the next financial year. Quantities of 20 cents have also been struck by the Royal Mint, Llantrisant and the Royal Canadian Mint”.
Engravers: Arnold Machin (obverse) Stuart Devlin (reverse).
