| Additional information |
São Tomé and Príncipe issued a wave of commemorative coinage in the late 1990s largely driven by export to collector markets rather than domestic circulation — the archipelago's tiny population and dollarized economy made large-format copper-nickel pieces economically impractical at home. The millennium theme was among the most aggressively marketed numismatic subjects of that decade, with dozens of small-nation issuers worldwide contracting with European minting houses to produce pieces aimed squarely at thematic collectors.
The KM#86a designation distinguishes the copper-nickel composition from a silver variant struck for the same issue.
