| Reverse description | The reverse features a vibrant holographic insert centrally placed within the coin, depicting a hummingbird in iridescent blue and green tones in flight, approaching a large tropical flower rendered in teal and black. The hologram produces shifting color effects — predominantly greens and blues — depending on the viewing angle, a hallmark of the holographic technology applied to this commemorative issue. The surrounding border is plain gold, framing the holographic element without additional lettering or inscription. |

| Additional information |
São Tomé e Príncipe issued this piece during a late-1990s wave of gold commemoratives aimed squarely at the collector export market — the domestic economy ran on the dobra at rates that made gold coinage entirely ceremonial. The hologram element was a novelty feature popular with certain Franklin Mint-adjacent producers of the period, more marketing device than minting tradition.
KM#83 is a low-mintage issue with limited auction visibility, suggesting a small and possibly unsold remainder.
