100 Dollars - Elizabeth II 6th Portrait - Australian Nugget - Gold Proof

The Australian Nugget series dates to 1986, when the Perth Mint launched it partly to compete directly with the Krugerrand and Maple Leaf in the global bullion market. The shift to the kangaroo motif — which rotates annually — came in 1989 after the original nugget designs proved less internationally recognizable. Proof versions like this one are struck multiple times with polished dies on burnished blanks, making them a distinct manufacturing exercise from the bullion strikes rather than simply a fancier version of the same coin.

The 6th portrait of Elizabeth II, by Jody Clark, was adopted by the Perth Mint beginning in 2019.
