The Australian two dollar coin was first brought into circulation in 1988 to replace the two dollar note and continues to circulate today. The first two dollar type was issued between 1988 and 1998 and featured the Maklouf portrait of HM Queen Elizabeth II. As this was the second type (after the Machin portrait) for all other circulating denominations for clarity this type is also referred to as Type II. The Type III was introduced in 1999 featuring the Ian Rank-Broadley portrait which continues to be issued today. In both of these types the obverse was the same design by Horst Hahne depicting an Aboriginal Elder. In addition to these standard types a large variety of two dollar commemorative pieces have been issued.
