The "Discover Australia" series, launched by the Perth Mint in 2008, used pad printing — an industrial ink-transfer process borrowed from commercial manufacturing — to apply color directly onto struck silver blanks. It was an unusual technical choice for a numismatic product, and early pieces in the series drew scrutiny over the long-term adhesion and fade resistance of the applied pigments.
Darwin itself was named after Charles Darwin, who visited the harbor briefly in 1839 aboard HMS Beagle.
