100 Dollars In the name of Elizabeth II, 6th Portrait - Kangaroo - Platinum Bullion

Perth Mint's platinum kangaroo bullion series competes in a market long dominated by the Platinum American Eagle and Platinum Maple Leaf, and Australia entered it relatively late — the kangaroo design in platinum was not formalized as an annual series until 1988, predating the Eagle by nearly a decade but finding its footing in investor demand only gradually. The "6th Portrait" designation marks the effigy introduced by Jody Clark for Commonwealth circulation coinage in 2015, subsequently adopted across Australian bullion issues.

Platinum at .9995 fineness exceeds the .9995 floor required by U.S. IRA regulations, making these eligible for inclusion in self-directed retirement accounts — a meaningful driver of North American demand.
