2010 150th Anniversary of the Burke and Wills Expedition Two Coin Uncirculated Year Set. On 20 August 1860, nineteen men set out from Melbourne to traverse Australia from south to north, a feat never achieved before. To celebrate the 150th anniversary of the epic Burke and Wills expedition, the Royal Australian Mint, in partnership with the Royal Society of Victoria released this stunning two coin set. The 20c coin illustrates Burke and Wills setting out and the $1 coin illustrates King, the sole survivor of the expedition, sitting under the 'Dig Tree'. On both designs, the camel tracks represent the expedition route and the footprints are symbolic of the assistance from the Aboriginal people. Mintage no more than 40,000.
