3000 Dollars - Elizabeth II 3rd Portrait - Australian Nugget - Gold Proof

The Australian Nugget series launched in 1986 as a direct competitor to the South African Krugerrand, timed deliberately to capture market share during the international sanctions-era boycott of South African gold products. This one-kilogram denomination sits at the apex of that program. The 1992 issue was struck in .9999 fine gold — four nines fineness — rather than the .9167 standard used by the Krugerrand, a purity distinction the Perth Mint marketed aggressively to institutional buyers.

Mintages for one-kilogram proof issues in this series were extraordinarily low, often in the single or double digits.
