Twenty Cents 2001, 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 2001.

The reverse design shows a swimming platypus as seen from above, among swirls of water.

The denomination numeral 20 [cents] is above the head of the mammal; the artist's initials SD (for Stuart Devlin) are in (very) tiny letters, within the swirl of water around its right forepaw.
