The Bank of Zambia has available for sale to members of the general public various numismatic coins. The coins were minted to commemorate various national and international historical events some of which date as far back as 1969. Coin collectors with much experience say numismatic coins have three main attractions: Rarity, Metallic Art and the Link between Coin and history. Of the three factors, history is probably the most compelling aspect in numismatics. Every little piece of coin has a story to tell. Most recently the Bank minted a K50 bimetallic coin to commemorate the 50 anniversary of the Bank of Zambia's founding.
