In 2012 the Royal Australian Mint released a very Limited Issue Kangaroo High Relief $1 One Dollar Silver Proof Coin struck in solid .999 Silver weighing one ounce of pure Silver.
The reverse design depicts a Kangaroo while the obverse has the stunning portrait of Her Majesty Queen Elizabeth II by Ian Rank Broadley.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
