2025 Australia 1 oz Gold Colorized Koala Proof (Box & COA)

---

The 2025 Australian Koala gold proof coin is a remarkable example of modern minting artistry, combining precious metal purity with vibrant color. Struck from one troy ounce of 99.99 percent pure gold, this legal tender release is backed by the Australian government and carries a face value of 100 Dollars. With a strictly limited maximum mintage of only 200 pieces, it represents a highly exclusive release within the celebrated Australian Koala series. On the reverse, a colorized depiction of a koala is nestled among the leaves and branches of a eucalyptus tree. This central design is accompanied by the year 2025, the traditional 'P' mint mark of the Perth Mint, and inscriptions detailing the coin's weight and gold purity. The contrast between the colored wildlife scene and the polished gold background highlights the exceptional craftsmanship of the proof finish. The obverse of the coin bears the official effigy of His Majesty King Charles III, designed by Dan Thorne, as indicated by the initials on the portrait. Surrounding the royal likeness are the inscriptions denoting the monarch's name, the issuing nation of Australia, and the denomination of 100 Dollars.
