Platinum Third-Ounce 2019 Humpback Whale, 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The Queen also wears the Coronation Necklace; originally made for Queen Victoria in 1858, it was also worn at the coronations (as Queen's Consort) of Queen Alexandra in 1902, Queen Mary in 1911 and Queen Elizabeth (the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 1/3oz 9995 Pt 2019 30 DOLLARS.

The inscription around the rim also incorporates the precious metal content. "1/3 oz 9995 Pt" means "one third of a troy ounce of 99.95% platinum" - Pt is abbreviated from platinum.

The reverse designs shows an adult humpback whale and a baby swimming in the ocean.

The Perth Mint's P mint mark is above right. On an air bubble above left, in tiny letters the initials of the designer, NH, for Neil Hollis.

In the rim, which is patterned with thin radial lines, the inscription 2019 HUMPBACK WHALE around above, and AUSTRALIAN ANTARCTIC TERRITORY around below.

Finish: bullion (Brilliant Uncirculated), frosted surfaces.
