The two dollar coin denomination (written as $2) was introduced in Australia in 1988, replacing the earlier banknotes. The original reverse design by Horst Hahne on circulating coins has not been changed since its introduction. The denomination is also often used to issue circulating commemorative coins with various reverses.
Apart from the circulating coinage, both the Royal Australian Mint and the Perth Mint have extensive programs issuing $2 coins for collectors (Non-Circulating Legal Tender, or NCLT), such as this one.
In 2010, the Royal Australian Mint produced - apart from the regular brilliant uncirculated, proof and silver proof coin sets - a commemorative gold coin set, the 2010 Gold Proof Set - Australian Numismatic Centenary. Unlike the other sets - which feature the regular effigy of the Queen by Ian Rank-Broadley, which was in circulation in Australia at the time - the coins in the gold set have her effigy by Vladimir Gottwald.
It is a uniquely Australian effigy, designed exclusively for the Royal Australian Mint, by its world renowned designer - Vladimir Gottwald. Acting on a worldwide invitation from Buckingham Palace in 1999, to design a more modern effigy of Queen Elizabeth II, Vladimir Gottwald’s design was eventually selected to honour Her Majesty’s royal visit of 2000 on a commemorative 50c coin.
The 6-coin set contains 5 cents, 10 cents, 20 cents, 50 cents, $1 and $2 coins - all with the Queen's portrait by Vladimir Gottwald.
The coins are made of 99.99% gold. No coins of this type were released into circulation. |
