The regular Proof and Uncirculated mint sets of the year had the 50 cents coin with the Queen's Fourth Portrait. Apart from coins issued into circulation, this coin - carrying Her Majesty's Fifth Portrait - was also issued in a special mint set called 50th Anniversary of the 50c Coin, Royal Australian Mint Product Code: 10211, issue price: A$65.00, marking 50 years of the dodecagonal coin. The set - with a mintage of 20,000 - features five 50-cent coins with identical reverses (the Australian Coat of Arms design), and five different obverses using each of the effigies of Queen Elizabeth II that have been in circulation in Australia on its decimal currency.
The first coin in the set is gold-plated and has the Queen's Second Portrait by Arnold Machin, used in Australia between 1966 and 1984.
The second coin has the Queen's Third Portrait by Raphael David Maklouf, used in Australia between 1985 and 1998.
The third coin has the Queen's Fourth Portrait by Ian Rank Broadley, used in Australia between 1999 and 2019 (this coin was also issued for circulation).
The fourth coin has the Queen's Gottwald portrait by Australian artist Vladimir Gottwald which was only used once for a circulation coin, on the 50 Cents commemorative coin for the 2000 Royal Visit.
This fifth coin has the Queen's Fifth Portrait by Jody Clark, which was introduced in Australia in 2019 (this coin was also issued for circulation). |
