| Reverse description | A Bennett's Cassowary (Casuarius bennetti) is depicted in left-facing profile, standing with head lowered amid a clump of native grasses, rendered in fine naturalistic relief. The large flightless bird is portrayed with detailed plumage texture, prominent casque, and powerful legs. The denomination numeral '20' appears to the left of the bird in the lower field, accompanied by the abbreviation 't' for toea. The design is enclosed within a beaded inner border running along the full circumference of the coin. |

KM#5a marks the transition from the original cupro-nickel 20 toea to nickel plated steel, a cost-driven reformulation that the Bank of Papua New Guinea implemented in the early 2000s as global nickel prices climbed sharply. Papua New Guinea adopted the toea at independence in 1975, with the denomination structure deliberately designed around local marine currency traditions — the word "toea" itself derives from a shell ornament historically used in trade among coastal communities of the Motu people.
