Non-decimal currency Non-decimal currency A non-decimal currency is a currency that has sub-units that are a non-decimal fraction of the main unit, i.e. the number of sub-units in a main unit is not a power of 10. Today only two countries in the world use non-decimal currencies. Both of these countries are in Africa. These are Mauritania (1 ouguiya = 5 khoums) and Madagascar (1 ariary = 5 iraimbilanja). However these are only theoretically non-decimal, as in both cases the value of the main unit is so low that the sub-unit is too small to be of any practical use and coins
Newfoundland one cent Newfoundland one cent As Newfoundland did not join the Dominion of Canada until 1949, it had its own currency for many decades. It adopted its own decimal currency in 1863. Compared to other pre-Confederation British colonies, it had a wide selection of decimal coinage (including a twenty cent coin). The most important coin in Newfoundland was the Spanish American dollar (the 8-real piece), therefore, the Newfoundland government set its dollar equal in value to this coin. The new decimal cent was equal to the British halfpenny and $4.80 was equal to one pound sterling. Varieties of 1880: Three date varieties
