1 Dollar - Elizabeth II 6th Portrait - The Great Aussie Coin Hunt 3 - Letter X, Silver Proof

The Great Aussie Coin Hunt series — now in its third iteration — was conceived by the Royal Australian Mint as a direct circulation engagement campaign, with lettered coins released through supermarket change. The silver proof versions exist entirely outside that circulation premise, produced for collectors who want the concept without the register queue. "X" is predictably among the harder letters to assign a distinctly Australian subject, and the Mint's choices across all three series have drawn persistent commentary from collectors about the creative constraints of a 26-letter alphabet imposed on national iconography.
