1000 Dobras Millennium

São Tomé e Príncipe issued a series of millennium-themed commemoratives in 1999 largely for the collector export market — a revenue strategy common among small island nations whose numismatic programs generate more foreign currency than their coins ever circulate domestically. The archipelago had weathered a difficult decade following the 1990 transition from single-party Marxist rule to multiparty democracy, and hard currency from collector sales mattered.

KM#99 is part of that broader series. Struck in sterling silver to standard modern commemorative specifications, these pieces were almost certainly produced under contract at a European mint rather than locally.
