Perth Mint: 40th Anniversary of the Australian Nugget 1 oz Gold 2026 Proof

Perth Mint: 40th Anniversary of the Australian Nugget is a prestigious gold collector coin struck from 1 oz of pure 9999 gold, issued in 2026 by The Perth Mint. The release commemorates the 40th anniversary of the Australian Nugget program, which since its debut in 1986 has become one of Australia’s most recognisable and highly regarded coin programs.

The Australian Nugget was the first legal tender gold coin program produced by The Perth Mint following the cessation of sovereign minting in 1931. From the outset, the series stood out for its artistic designs by the world-renowned goldsmith and numismatic designer Stuart Devlin, celebrating historic Australian gold nuggets and the legacy of the gold rush.

The coin is struck in the Proof standard with the highest minting precision. It has a face value of 100 Australian dollars, a diameter of 32.6 mm and a weight of 31.107 g. The issue is strictly limited to just 200 pieces, making this coin exceptionally rare and highly sought after among collectors of commemorative gold coins.

The obverse of the coin features the official effigy of King Charles III by Dan Thorne, accompanied by the face value, in the style characteristic of contemporary The Perth Mint issues.

The reverse depicts the legendary Welcome Stranger nugget, the largest gold nugget ever discovered, found in 1869 in Moliagul, Victoria. The motif is surrounded by an outlined map of Australia and a ring of stylised sun rays. The composition includes the name of the nugget, the P40 mintmark, the inscription THE AUSTRALIAN NUGGET, as well as details of the weight, gold fineness and the year of issue 2026.
