20 Kwacha

Zambia's first post-independence banknote series, of which this is part, was introduced in 1968 following the country's break from the Rhodesian pound system — itself a casualty of UDI and the economic rupture between Lusaka and Salisbury. The 20 Kwacha sat at the top of that inaugural series, a high denomination in a country where copper export revenues were funding rapid state expansion under Kaunda's government.

The two signatures — Valentine Musakanya as Governor and Elijah Zulu as Finance Minister — place this note within a narrow window. Musakanya left the governorship in 1970, making dated examples from 1969 among the last bearing that pairing.
