In 2009 to celebrate the 20th Anniversary of the first Kookaburra, the Perth Mint released a very Limited Issue Kookaburra $5 Five Dollar Gold Proof Coin struck in solid fine .9999 Gold and weighing one twentieth of an ounce of pure Gold with a special P20 Mint Mark.
The reverse depicts a Kookaburra 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.
