In 2013 the Perth Mint released a very Limited Issue Mini Koala 10c Ten Cent Silver Coin struck in solid .999 Silver weighing one tenth of an ounce of pure Silver with a special "P" Mint Mark.
The reverse depicts an adult Koala resting on the fork of a eucalyptus tree while the obverse features the stunning portrait of Her Majesty Queen Elizabeth II by Ian Rank Broadley.
