100 Dollars - Charles III 1st Portrait - Super Pit - Gold Bullion

The Super Pit — formally the Fimiston Open Cut — is one of the largest open-cut gold mines in the world, sitting on the edge of Kalgoorlie in Western Australia. Operations there trace back to the 1890s gold rush, though the current consolidated pit took shape in 1989 when several competing mines were merged under Kalgoorlie Consolidated Gold Mines. At peak production, the site was blasting rock on a schedule precise enough that Kalgoorlie residents set their clocks by it.

Charles III's first portrait on Australian coinage, sculpted by Samlane Thienpont, debuted in 2023 following the King's accession.
