To celebrate sixty years since Her Majesty Queen Elizabeth II was crowned in 1953 the Royal Mint, the Royal Canadian Mint, and the Royal Australian Mint produced a three coin set. The three coin set was issued in either gold or silver. This fifty cent piece, designed by Michael Meszaros, was the Royal Australian Mint's contribution to the set. The modern reverse features a diamond with the silhouette of St. Edward's Crown in the centre and a branch from a golden wattle, the Australian floral emblem, within the crown. The reverse legend states "THE QUEEN'S DIAMOND JUBILEE 2012". The obverse features the Ian Rank-Broadley portrait of HM with the legend "ELIZABETH II AUSTRALIA 2012".
The coronation of Queen Elizabeth II occurred on the 2nd of June 1953. The coronation service took place in Westminster Abbey in London in front of a more than 8,000 guests. The ceremony was also the first British coronation to be televised and was watched by an astounding 20 million on BBC coverage. The service was complex and long with Queen Elizabeth swearing an oath of governance, being anointed with a holy oil, presented with the royal regalia, and finally crowned by the Archbishop of Canterbury as the crowd shouted "God save the Queen!".
