10 Dollars - Elizabeth II 4th Portrait, Spirit of ANZAC

Issued to mark the centenary of the Gallipoli landings, this coin appeared during a year of exceptional commemorative output from New Zealand — the ANZAC centennial prompted one of the largest coordinated memorial programs in the country's modern history. The April 25, 1915 landings cost New Zealand roughly 2,700 casualties in eight months of fighting on the peninsula, a loss felt acutely in a country then numbering fewer than one million people.

The 7.78g gold specification places it precisely at one-quarter troy ounce.
