 In 1860, the colonies of New Brunswick and Nova Scotia followed the Province of Canada in adopting a decimal system based on the U.S. dollar unit.Newfoundland went decimal in 1865, but unlike the Province of Canada, New Brunswick, and Nova Scotia, it decided to adopt a unit based on the Spanish dollar rather than on the U.S. dollar, and there was a slight difference between these two units.The U.S. dollar was created in 1792 on the basis of the average weight of a selection of worn Spanish dollars.
