30 Dollars - Charles III 1st Portrait - Year of the Snake - Silver Coloured - Gold Privy

Perth Mint's kilogram lunar issues have been produced annually since the series launched in 1999, making this the third full cycle through the Chinese zodiac. The Snake year sits fifth in the twelve-year rotation, and the kilogram denomination in this series consistently draws the strongest secondary-market premiums of any size tier — the gold privy mark adds a production distinction that separates it from the standard kilogram release, functioning as a limited subset within an already finite mintage.

Charles III's first portrait, by sculptor King Gillick, began appearing on Australian coinage in 2023 following the September 2022 accession.
