10 Dollars - Elizabeth II 4th Portrait - ANZAC Centenary - Gold Proof

The ANZAC Centenary commemorative program of 2015 was one of the most extensive coin release schedules in Australian mint history, spanning multiple denominations, compositions, and mintage tiers across a full calendar year. This gold proof issue corresponds with the centenary of the Gallipoli landings of 25 April 1915 — a campaign conceived by Churchill and prosecuted by allied commanders with catastrophic miscalculation, resulting in over 8,700 Australian deaths in eight months before evacuation.

At 3.11 g of .999 gold, the specification matches a one-tenth troy ounce format — a deliberate accessibility price point for collector demand during a politically high-visibility anniversary year.
