Sales History


The Type I twenty cent was issued from 1966 to 1984 with an additional proof striking in silver in 2006 as part of the 40th anniversary of decimal coinage set. It features a platypus on the reverse and her majesty Queen Elizabeth II on the obverse .The issue was struck at the Royal Australian Mint in all years with additional assistance provided by the Royal Mint London in 1966 to assist with the huge demand for new currency as a result of the vast amount of pre-decimal currency withdrawn. In 1982,the Wales mint assisted with striking coins to meet the additional demand for circulation currency brought about by the economic boom of the 1980s.
