100 Leones

Thomas De La Rue printed this series across a three-year window bracketing one of Sierra Leone's more turbulent fiscal periods — the country was operating under an IMF structural adjustment programme and suffering severe inflation that would eventually necessitate a complete currency reform in the early 1990s. The 100 Leones, effectively a mid-range note when introduced, was eroded to near-insignificance in purchasing power by the time the series closed.

Watermark-only security was already conservative by late 1980s standards, and the notes circulated hard in a cash-dependent economy with limited banking infrastructure. Heavily worn examples vastly outnumber clean ones.
