| Obverse description | The obverse features the coat of arms of the Democratic Republic of the Congo centrally placed in the field, depicting a leopard's head facing forward flanked by a crossed elephant tusk and spear, mounted on a base inscribed PAIX, with the words JUSTICE and TRAVAIL appearing on either side. The circular legend REPUBLIQUE DEMOCRATIQUE DU CONGO runs along the upper periphery, while the denomination 20 FRANCS is prominently displayed along the lower rim. The fineness and weight designation 1 oz Ag 999.9 appears in the lower field, just above the denomination. The design is rendered in a frosted relief against a mirror-polished background, consistent with proof-quality striking. A beaded border frames the entire composition. |

| Additional information |
Titanoboa cerrejonensis was excavated from the Cerrejón coal mine in Colombia in 2009 and identified as the largest snake known to have existed — roughly 13 meters long, weighing over a metric ton, and living approximately 60 million years ago in a post-extinction tropical environment so warm it could sustain cold-blooded animals at that scale. The Democratic Republic of Congo has no particular paleontological connection to the species; this is a bullion-adjacent collector issue capitalizing on prehistoric megafauna, a category that has driven significant secondary-market premiums since roughly 2018.
The KM#389.1 variant designation suggests a die or finish variant exists within the same year of issue — likely a privy mark or surface treatment difference rather than a compositional change.
