In 1999, the Perth Mint released a Limited Issue Bi-Metal $100 One Hundred Dollar Gold Proof Sovereign Coin to commemorate the 100th Anniversary of the opening of the Perth Mint.
It features a solid 22ct Gold centerpiece, with the same specifications as the original Perth Mint Sovereign and is surrounded by a 99.99% pure silver border.
The Perth Mint Centenary Sovereign honours both the historic role of the sovereign and the importance of silver in the Mint's heritage.
The Perth Mint has been Australia's major gold and silver refiner since 1899 and 100 years on, it is still producing gold and silver coins for investors and collectors around the world.
The gold centerpiece of the Perth Mint Centenary Sovereign replicates the original reverse design of St George Slaying the Dragon, as featured on all Perth Mint Sovereigns.
The design is distinguished by the Perth Mint Centenary Mint Mark 'P100' positioned where the date would normally be shown on the reverse. The silver border incorporates the words 'The Perth Mint Centenary Sovereign 1899 - 1999'.
On the obverse is the stunning portrait of the Queen by Ian Rank Broadley.
These legal tender coins have been struck to proof quality using specially prepared dies and highly polished blanks.
