10 Dollars - Elizabeth II Saumarez Reefs

The Saumarez Reefs sit roughly 300 kilometres east of the Queensland coast in the Coral Sea, administered under the Coral Sea Islands Territory — one of Australia's more obscure external territories, with no permanent population and a weather station as its sole infrastructure. This coin is part of Australia Post's ongoing Coral Sea Islands series, which has used pad printing on silver-plated cupro-nickel to render the kind of full-colour detail that conventional minting processes cannot achieve on a curved surface. The technique bonds ink directly to the planchet under pressure rather than heat.
