Silver Ten Ounces 2021 Mother and Baby Platypus, Coin from Australia - detailed information

The obverse of the coin depicts the crowned old bust of Queen Elizabeth II facing right, wearing the Royal Diamond Diadem crown worn for her Coronation (effigy known as the "Fifth Portrait" worldwide but "Sixth Portrait" in Australia, where the Queen's portrait by Vladimir Gottwald was fifth).

The Queen also wears the Coronation Necklace; originally made for Queen Victoria in 1858, it was also worn at the coronations (as Queen's Consort) of Queen Alexandra in 1902, Queen Mary in 1911 and Queen Elizabeth (the Queen mother) in 1937.

Unlike on British coinage, the effigy is "uncouped" (includes the Queen's shoulders). In small letters on the left, the artist's initials JC (for Jody Clark).

Running continuously around the rim is the monarch's legend, the date of issue and the face value: ELIZABETH II AUSTRALIA 10oz 9999 Ag 2021 10 DOLLARS.

The inscription around the rim also incorporates the precious metal content. "10 oz 9999 Ag" means "ten troy ounces of 99.99% silver" - Ag is abbreviated from the Latin word for silver, Argentum.

The background is of radial lines radiating from the centre of the portrait.

The coin’s reverse depicts Australia’s iconic platypus swimming with its baby, on a background of radial lines.

In small letters below, the designer's initials MR (for Monique Reeves). The Perth Mint's traditional P mint mark is on the left (or right? the Mint-supplied image has two?).

There is no inscription.

Silver content in Troy oz: 10.000
Finish: Brilliant Uncirculated, on extra-thick blank.
Packaging: in a protective acrylic capsule.

Each coin’s reverse includes a security feature in the form of a micro-laser engraved letter within the design. It is only detectable under a magnifying glass.
