In 2013 to celebrate the Koala, the Perth Mint released a very special Limited Issue Koala $200 Two Hundred Dollar Gold Proof Coin struck in solid fine .9999 Gold weighing two ounces of pure Gold and struck in High Relief.
The reverse depicts an adult Koala sitting on the branch of a eucalyptus tree, surrounded by gum leaves while the obverse has Ian Rank Broadley's portrait of Her Majesty Queen Elizabeth II.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
