2026 $100 Great Southern Land Chrysoprase 1oz Gold Proof Coin

Celebrating the flora and fauna of Australia’s iconic rainforest, the coin depicts (clockwise from top-right), a flying fox, a possum, a tree snake, a kingfisher, a crocodile, a butterfly, a tree frog, a cassowary, an orb-weaving spider, and other birds. The design encircles an Australia-shaped insert of chrysoprase, a gemstone that derives its green colour from nickel. Found in Queensland and Western Australia, ‘Australian jade’ as chrysoprase is sometimes known, makes an eye-catching jewellery stone when polished. As each insert is crafted from natural green chrysoprase stone, inherent variations in coloration and patterning are to be expected. Consequently, every coin in the mintage may display a unique appearance.
