The 2026 1oz Australian Gold Kangaroo bullion coin is a standout modern issue because The Perth Mint marks the 40th anniversary of the Australian Nugget with a special privy mark on the reverse. Struck from one troy ounce of 99.99% pure gold, it features the 2026 kangaroo design, Australian legal tender status, a micro-laser authentication feature and protective capsule presentation, giving it stronger collector character than a routine annual bullion date.
