1 Dollar - Elizabeth II 4th Portrait - Armistice Centenary 1918-2018

Australia lost approximately 62,000 dead in the First World War — the highest per-capita casualty rate of any Allied nation. The centenary of the November 1918 armistice prompted commemorative programs across the Commonwealth, and the Royal Australian Mint issued this piece as part of a broader national remembrance effort tied to the Australian War Memorial's own centenary programming.
