Stretching more than 2,300 kilometres along Australia’s Queensland coast, the Great Barrier Reef is the world’s most extensive coral reef ecosystem. Comprising more than 2,500 reefs and over 900 islands, it supports extraordinary biodiversity, including 600 species of coral, more than 1,500 types of fish and thousands of different molluscs. It is also home to dugongs, whales, dolphins, sharks, rays and six of the world’s seven species of marine turtle.
Green Turtle Design
Against a detailed background composed of fish, coral, seagrass and jellyfish, the coin portrays a green turtle which feeds and nests throughout the entire Great Barrier Reef area. Also included in the design is The Perth Mint’s ‘P’ mintmark.
In a nod towards the Reef’s extraordinary age, estimated at over 500,000 years, the coin surface is antiqued, a treatment that tones the natural lustre of silver before it is individually hand finished to mimic the unique characteristics often seen on an ancient artefact.
The obverse of the coin also portrays a guilloche pattern, with each coin's edge individually numbered from 1 to 200.
The coin is encased within a clear Perspex display that sits within a timber presentation case and box shipper. Each coin in the mintage is accompanied by a numbered Certificate of Authenticity.
