200 Dollars - Charles III 1st Portrait - Great Southern Land - Gold

The "Great Southern Land" series draws on Australia's geological identity as one of the oldest and most stable continental cratons on Earth — the Yilgarn Craton underlying much of Western Australia dates to roughly 3.7 billion years, older than most surface rock anywhere on the planet. The Perth Mint's two-ounce .9999 fine gold format places this squarely in the premium bullion tier the mint has pursued aggressively since the late 1990s, competing directly with the Royal Canadian Mint's similarly specced issues.

Charles III's first effigy for Australian coinage, sculpted by King's sculptor-in-ordinary Jody Clark, debuted across Commonwealth mints in 2023.
