2011 Australia 1 oz Platinum Platypus BU

---

In 2011, the Australian Bullion Coin Program introduced a brand new design to its lineup, marking the very first year of issue for a series dedicated to one of the world's most unusual creatures. Struck in one troy ounce of highly refined 0.9995 fine platinum, this legal tender piece carries a face value of 100 Dollars. The coin's production was strictly limited, with a total mintage of only 30,000 pieces released to the public, all backed by the official guarantee of the Australian Mint. The reverse of the coin captures an elegant underwater scene featuring a platypus submerged in its natural aquatic environment. Accompanying this unique wildlife illustration are inscriptions detailing the coin's year, its weight of one ounce, and its high platinum purity. On the obverse, the coin displays the classic portrait of Queen Elizabeth II, designed by artist Ian Rank-Broadley, alongside the official face value of 100 Dollars, completing a beautiful harmony of modern minting artistry and natural history.
