This stunning antiqued design symbolises the Great Barrier Reef’s unique importance to thousands of different marine species. Stretching more than 2,300 kilometres along Australia’s Queensland coastline, 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 dugong, whales, 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 reverse of the coin portrays a green turtle which feeds and nests throughout the entire Great Barrier Reef area. The design also includes the inscription ‘GREAT BARRIER REEF 2021 2 KILO 9999 SILVER’ and The Perth Mint’s traditional ‘P’ mintmark.

The obverse of the coin portrays a guilloche pattern, the Jody Clark effigy of Her Majesty Queen Elizabeth II and the monetary denomination. The coins are individually edge numbered from 1 to 200.

Technical Notes

The coin’s high relief reverse and obverse are minted on concave surfaces to ensure the optimum flow of metal is achieved by the strike of the die. In a nod towards the Reef’s extraordinary age, estimated at over 500,000 years, the coin has been individually ‘antiqued’ to give it a unique finish conveying the surface abrasions of an ancient artefact. As a result of this treatment the appearance of each coin may vary.

Presentation Packaging

The coin is housed in a stunning clear case, which makes a perfect display piece. The case sits within a wooden presentation box and is accompanied by a numbered Certificate of Authenticity.
