After the passing of Queen Elizabeth II in 2022, and the accession of King Charles III, Australia set about the most significant revision of decimal currency since the introduction of decimal currency itself. For the first time in more than seven decades, the coins of Australia would carry the portrait of a monarch other than the queen. Ultimately, the portrait of King Charles III by the Royal Mint’s Daniel Thorne was chosen, and the transition to our new coinage began in earnest. The 2025 6-Coin Silver Proof Set is an exclusive, eternal keepsake of the successful conclusion of that process.
