 The exchange rate was set to one kwacha equivalent to ten Zambian shillings, or one half of a Zambian pound.Thus, by January 16, 1968, all Zambian pound notes and coins were removed from circulation and replaced by the new kwacha notes, and ngwee coins.The Zambian pound notes of 10 shillings, 1, and 5 pounds were changed into 1, 2 and 10 kwacha respectively, a note of 50 ngwee was issued to replace the old 5 shillings coin, alongside a new note of 20 kwacha.
