Perhaps Australia's greatest ever military leader, Sir John Monash was a great man before, during, and after World War I. On the battlefield, Monash was behind some of Australia's most significant achievements, including Gallipoli, and the Battle of Hamel. In 1918, Sir John Monash was officially knighted by King George V.
In 2018, the Royal Australian Mint honours this great military leader with a special Aluminium-Bronze $1 coin. The same size and composition as the coin in your change, this coin - with a mintage of only 20,000 - will never be found in circulation. This is the only way to add it to your collection!
