1000 Dobras Heidiland

São Tomé e Príncipe issued a series of collector-oriented pieces in the 1990s featuring Swiss cantonal imagery — an unusual pairing for a West African island nation with no historical connection to Switzerland. These were produced for the international numismatic market rather than domestic circulation, a common revenue strategy for small sovereign states with limited export economies. The Banco Central issued dozens of such themed pieces across this decade, few of which ever reached the archipelago itself.
