100 Shillings

The 1985 Uganda 100 Shillings arrived during a period of extreme monetary instability — by the mid-1980s, inflation had so severely eroded purchasing power that the 100 Shilling note, once a meaningful denomination, had become effectively worthless in daily commerce. Milton Obote's second government, which oversaw this issue, was itself overthrown by Tito Okello in July 1985, meaning notes dated this year were authorized under one administration and circulated under another.

De La Rue's involvement was continuous across Uganda's banknote history from independence onward, and the P#21 series followed the same watermark-only security specification as its immediate predecessors — a notably sparse security profile given the counterfeiting pressures common in the region at the time.
