Coins In 1967, coins were introduced by the National Bank of Congo in denominations of 10 sengi, 1 likuta and 5 makuta, with the lower two denominations in aluminium and the highest in cupro-nickel. In 1973, the first coins issued by the Bank of Zaire were issued, cupro-nickel 5, 10 and 20 makuta. In 1987, a new coinage was introduced, consisting of brass 1, 5 and with a 10 zaires in 1988. Banknotes In 1967, the National Bank of Congo introduced notes for 10, 20 and 50 makuta, 1 and 5 zaires (also shown as 100 and 500 makuta). In 1971, 10 zaire notes were introduced. In 1972, the Bank of Zaire started issuing notes for 1, 5 and 10 zaires, followed by 50 makuta notes in 1973. 50 zaïre notes were introduced in 1980, followed by 100 zaires in 1983, 500 zaires in 1984, 1000 zaires in 1985, 5000 zaires in 1988, 10,000 zaires in 1989, 2000, 20,000 and 50,000 zaires in 1991 and, finally, 100,000, 200,000, 500,000, 1,000,000 and 5,000,000 in 1992. The 5,000,000 zaire note, which entered circulation in late 1992, was not accepted as legal tender for several weeks in some parts of the country (notably in the north-east), and in other parts of the country it was accepted for only part of its value. One reason for this mistrust was a grammatical error in the French number on the note, which read "cinq millions zaïres" instead of "cinq millions de zaïres". New Zaire (1993–1998) The New Zaire (), symbol "NZ", ISO 4217 code ZRN, replaced the first zaire in 1993 at an exchange rate of 1 new zaire = 3,000,000 old zaires. It was subdivided into 100 new makuta (symbol: "NK"). This currency was only issued in banknote form and suffered from extremely high inflation to its predecessor until 1997. Below is a series of reported exchange rates by the U.S. Treasury (new zaires per USD): March 1994: 115 June 1994: 450 September 1994: 1,650 to 2,450 March 1995: 2,850 June 1995: 4,900 September 1995: 6,153.85 December 1995: 15,550 March 1996: 23,368 June 1996: 33,367 September 1996: 54,306 December 1996: 93,076 March 1997: 142,560 June 1997: 125,000 September 1997: 115,000 December 1997: 116,000 March 1998: 125,000 June 1998: 133,000 September 1998: 150,000 (1.50 CDF) December 1998: 240,000 (2.40 CDF) The new zaire was replaced by the Congolese franc again on 1 July 1998, at an
