Struck in .9995 platinum bullion by Australia's Perth Mint, only 30,000 of these unique 1 oz Platinum Platypus Coins were released in 2011.
The platinum coin’s reverse face features the remarkable Australian animal, the platypus, which is one of the world’s only two egg-laying mammals. An effigy of Her Majesty Queen Elizabeth II appears on the obverse surface of these legal tender Australian platinum coins.
