The 2025 1oz Gold Australian Lunar Series III Bullion Coin celebrates the Year of the Snake in The Perth Mint’s Chinese zodiac bullion programme. Struck in one troy ounce of .9999 fine gold, it combines Australian legal tender status, Perth Mint production quality and a changing annual lunar reverse that appeals to both bullion investors and date-run collectors. The 2025 Snake continues the King Charles III era of Series III, with modern authentication-style bullion presentation and strong Perth Mint recognition.
