50 Cents

Sierra Leone's small-denomination notes of this series were produced during a period of acute fiscal pressure — the country had nationalized the Bank of Sierra Leone in 1971 and was, by the late 1970s, managing a currency increasingly undermined by inflation and IMF structural adjustment demands. The 50 Cents note continued to circulate well into the early 1980s despite its purchasing power eroding sharply against the leone's declining real value.

Thomas De La Rue handled the full series, as they had for Sierra Leone since independence. The relatively long issue window — five years — suggests reprinting in batches rather than a single continuous run, though distinguishing print dates within P#4 requires close attention to serial prefix groupings.
