200 Dollars - Elizabeth II 4th Portrait - End of WWI 100th Anniversary

Australia's involvement in WWI ended not at the Armistice on 11 November 1918 but legally concluded with the Treaty of Versailles in 1919, a distinction the Commonwealth government was deliberate about — Australia signed the treaty independently, one of the first times it acted as a sovereign nation in international law rather than as a British dominion. The "pad printed" designation here refers to a polychrome color application process Perth has used selectively since the 2010s, transferring ink onto the coin's surface under controlled pressure rather than enamel inlay.
