In 2014 to celebrate the Koala , the Perth Mint released a very Limited Issue Koala $1 One Dollar Silver Proof High Relief Coin struck in solid fine .999 Silver weighing one ounce of pure Silver.
The reverse design depicts the Koala
ones of Australia‘s cuddliest marsupials while the obverse features Ian Rank Broadleys 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.
