2015 Australia 1 oz Platinum Platypus BU

---

The 2015 Australian Platypus coin is a remarkable tribute to one of the most unusual creatures on Earth. Struck from one troy ounce of 99.95 percent pure platinum, this issue represents the fifth entry in the celebrated Australian Bullion Coin Program. The coin's design highlights the unique nature of its subject, a semi-aquatic mammal native only to the freshwater lakes and rivers of eastern Australia. It is one of just five surviving mammal species that reproduce by laying eggs rather than giving birth to live young. On the reverse side, the coin depicts a detailed scene of a platypus diving gracefully underwater. This side also bears the inscriptions confirming its status, including the words AUSTRALIAN PLATYPUS and its weight and purity of 2015 1oz 9995 PLATINUM. The artistry captures the sleek, streamlined form of the creature as it navigates its aquatic habitat. The obverse displays the familiar profile of Queen Elizabeth II, designed by Ian Rank-Broadley, alongside the face value of 100 DOLLARS. This brilliant uncirculated coin was produced with a strictly limited release of only 12,420 pieces, making it a fascinating study for those who appreciate specialized world coinage and unique biological themes.
