originally, a silver coin that circulated in many European countries; in modern times, the name of the standard monetary unit in the United States, Canada, Australia, New Zealand, and other countries. The Spanish peso, or piece of eight, which circulated in the Spanish and English colonies in America, was known as a dollar by the English-speaking peoples. Familiarity with this coin resulted in the official designation of the United States monetary unit as the dollar in 1792. Canada adopted the dollar and monetary decimal system in 1858; Australia in 1966; and New Zealand in 1967.
