Ten Cents 2000, Coin from Australia - detailed information

The obverse shows the crowned mature head of Queen Elizabeth II facing right (her 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 small 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 2000.

The reverse of the coin depicts a lyrebird seen facing left, with its tail plumes expanded forward over its head.

The denomination numeral 10 [cents] is above the head of the bird; the artist's initials SD (for Stuart Devlin) are in (very) tiny letters below, in the right field beside its foot.
