This twelve-coin set was issued by the Royal Australian Mint to celebrate the 30th anniversary of the $2 denomination.
The coins are in Brilliant Uncirculated grade and feature a variety of obverses and reverses as issued by the Royal Australian Mint in the $2 denomination from its introduction 30 years earlier until 2018.
The mint says about it:
Exactly thirty years ago, Australia’s two dollar note was retired and the two dollar coin was born. Today (20 June 2018) the Royal Australian Mint (the Mint) celebrates the two dollar coin’s thirtieth birthday, looking back at designs and themes the coin has marked over three decades.
The two dollar coin was introduced on 20 June 1988 following a decision by the Treasurer, Paul Keating, to replace the two dollar notes as they were damaged too easily. Since then approximately 864 million two dollar coins have been produced by the Mint.
Numerous designers were invited to contribute designs for the two dollar coin based on a brief to include a representation of the head and shoulders of an Aboriginal Australian, the Southern Cross and Australian flora. The chosen design was prepared by Mr Horst Hahne, with inspiration taken from an original artwork by Mr Ainslie Roberts.
To acknowledge thirty years of the two dollar coin, the Mint has produced a commemorative set that unites twelve of the designs that have entered into general circulation, including Anzac Day and Remembrance Day releases. The set is a celebration of the heritage, creativity and engineering excellence for which the Royal Australian Mint is renowned. |
