The 2019 Humpback Whale platinum coin pairs an unusual fractional format with one of the ocean’s most beloved giants, struck by the Perth Mint in 1/3 troy oz of .9995 fine platinum with a $30 AUD face value. Issued for the Australian Antarctic Territory series, it stands among the few third-ounce platinum coins ever offered, giving investors a distinctive size and a one-year design in a single piece.
Key Features:
- Purity and Weight: 1/3 troy oz of .9995 fine platinum, $30 Australian legal tender
- Metal: Investment-grade platinum from the Perth Mint
- Obverse Design: Jody Clark’s crowned effigy of Queen Elizabeth II
- Reverse Design: A humpback whale and calf swimming beneath drifting ice
- Limited mintage of 25,000 coins
The obverse carries Jody Clark’s sixth-effigy portrait of Queen Elizabeth II, the monarch shown in the Royal Diamond Diadem with pearl necklace and earring. ELIZABETH II AUSTRALIA wraps the upper rim, while the specifications 1/3 oz 9995 Pt, the 2019 date, and the 30 DOLLARS denomination complete the inner legend below the portrait.
The reverse dives beneath the Southern Ocean, where a humpback whale glides with a calf at its side, the adult’s long pectoral fins, pleated throat grooves, and barnacled hide engraved in fine texture. Broken pack ice drifts across the surface above the pair, grounding the scene in Antarctic waters. 2019 HUMPBACK WHALE arcs across the top, AUSTRALIAN ANTARCTIC TERRITORY sweeps the lower border, and the P mintmark of Perth sits in the right field, all framed by a ribbed outer ring that gives the coin a distinctive machined edge.
Platinum coins are struck in tiny numbers next to gold and silver, and this series retired its whale design after 2019. The .9995 fineness also keeps the coin eligible for precious metals IRAs.
Scarce metal, a scarcer size, and a mother-and-calf scene with genuine charm make this coin a conversation piece that stacks. Order the 2019 Humpback Whale 1/3 oz platinum coin today.
