| Reverse description | A finely detailed, naturalistic depiction of the Goliath Birdwing butterfly (Ornithoptera goliath) in full dorsal spread occupies the central field, its intricately engraved wing venation and hindwing ocelli rendered in high relief. The butterfly is shown with wings fully extended, antenna raised, and body in the centre, filling the heptagonal field with remarkable sculptural precision. The denomination legend 'K100' appears in large bold characters above the butterfly in the upper field. A continuous beaded border encircles the inner rim of the coin on all seven sides. |

| Additional information |
Papua New Guinea achieved independence in September 1975, and the new nation moved quickly to establish a coinage identity rooted in its extraordinary endemic fauna. The Queen Alexandra's Birdwing — the world's largest butterfly, found only in a narrow range of Oro Province — was a pointed choice for a prestige gold issue, already legally protected under PNG law at the time of minting.
KM#13 had a low mintage and was produced primarily for the collector market, with virtually no circulation exposure.
