1 Leone

Sierra Leone redenominated its currency in 2022, replacing the old leone at a rate of 1,000 to 1 — meaning this note's face value was effectively one million of the pre-reform leones. The redenomination was driven by decades of accumulated inflation rooted in the country's civil war period and its aftermath, during which monetary discipline had essentially collapsed.

De La Rue produced the series on cotton substrate with a modest security specification — watermark and thread only, which reflects the low face value's practical circulation role rather than any cost-cutting anomaly.
