 Although the old 20 kwacha note was still in circulation until 2012, such is the rarity of this note that most major retailers rounded prices up to the nearest 50 kwacha when calculating a total.Most items in major supermarkets were displayed using 20 kwacha in the value (e.g., 1980 kwacha).On January 23, 2012, the Bank of Zambia proposed certain measures in regards of the redenomination of the Zambian kwacha.
