15 Dollars - Elizabeth II 4th Portrait - Discover Australia - Goanna - Platinum Proof

The Discover Australia series, launched by the Perth Mint in the mid-2000s, used fractional platinum issues to target the high-end collector market at a time when platinum briefly surpassed gold in spot value. The goanna entry in this series corresponds to the lace monitor, one of Australia's largest living lizards and a species with genuine cultural weight in Aboriginal tradition — though the coin's framing is zoological rather than ethnographic.

KM#1852 is a low-mintage proof struck to the Perth Mint's standard of .9995 fine, with production numbers kept deliberately tight to sustain secondary market premiums.
