50 cent, 2005: world war II
This is a commemorative 50 cent coin of Australia. The world war started in 1939 and 1945. This coin was minted in 2005, so it means its remembrance of the event, on the occasion of 60 years of the ending of the war. The coin is in remembrance, an ode to those who lost their lives in the catastrophic event which is known as world war II. Some people might say that Australia was not among one of the Axis or the Allied powers, but then they forget that Australia was a part of England in the second world war.
