This commemorative definitive stamp from Sierra Leone features a finely engraved portrait of Queen Elizabeth The Queen Mother, symbolizing the historical ties between Sierra Leone and the British Commonwealth. The stamp bears a bold “Le 800” overprint, indicating a revalued denomination issued during a period of postal rate adjustment. Such provisional overprints are particularly attractive to collectors because they document economic and postal transitions in a country’s history. The elegant sepia-toned design and clear typography enhance its classic philatelic appeal. Well-preserved examples are valued additions to Commonwealth thematic or overprint collections.
