One Dollar 2013, Coin from Australia - detailed information

The one dollar coin denomination was introduced in Australia in 1984, replacing the earlier banknotes. The original reverse design by Stuart Devlin has not been changed since the introduction.

Coins issued in 2013 have now been in circulation for six years.

Crowned mature head of Queen Elizabeth II facing right (effigy known as the "Fourth Portrait"). The Queen wears the "Girls of Great Britain and Ireland" diamond tiara, a wedding gift from Queen Mary (Her Majesty's grandmother) in 1947 - which she also has on the Machin and the Gottwald portraits.

In tiny letters below the head, the artist's initials IRB (for Ian Rank-Broadley).

Around the effigy is the monarch's legend and the date: ELIZABETH II AUSTRALIA 2013.

Five kangaroos (hence the coin type is known as the "Mob of Roos"), the closest facing right but looking to left; below, and overlaid on them, the denomination and value 1 DOLLAR.
