In 2000 to celebrate the Kookaburra, the Perth Mint released a special Limited Issue Kookaburra Silver Proof 4 Coin Collection all struck in solid fine .999 Silver.
The collection includes the Australian Kookaburra $30 Thirty Dollar Silver Proof Kilo Coin, $10 Ten Dollar Silver Proof 10oz Coin, $2 Two Dollar Silver Proof 2oz Coin and the $1 One Dollar Silver Proof 1oz Coin.
The reverse of each coin depicts the Kookaburra and the obverse is 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.
