The Platinum Australia Platypus was first struck by Australia’s Perth Mint in 2011. The Platinum Australian Platypus features Ian Rank Broadley’s portrait of Queen Elizabeth II on the obverse and a platypus on the reverse. This meticulously detailed coin serves as an outstanding representation of the lustrous properties of platinum, exemplified in the frosted, luminous finish. Each Platinum Australian Platypus contains 1 oz of .9995 fine platinum bearing a face value of $100 Australian dollars.
