1000 Dollars - Elizabeth II 4th Portrait - Discovery - Gold Bullion Coin

Perth Mint's "Discovery" bullion series commemorates the gold rushes that transformed colonial Australia from the 1850s onward — events that directly caused the founding of the Perth Mint itself, established in 1899 to process the flood of gold from Western Australian fields. The Coolgardie and Kalgoorlie strikes of the early 1890s made Western Australia briefly the most productive goldfield on earth.

The diamond inset — a genuine black diamond set into the coin — was a deliberate engineering challenge for the Mint's production team, requiring precision tolerancing to survive legal tender handling. Few sovereign mints have attempted stone-set bullion at this weight class.
