The peso is the monetary unit of several Spanish-speaking countries in Latin America, as well as the Philippines. Originating in the Spanish Empire, the word peso translates to "weight". In most countries of the Americas, the symbol commonly known as dollar sign, "$", was originally used as an abbreviation of "pesos" and later adopted by the dollar. The dollar itself actually originated from the peso or Spanish dollar in the late 18th century. The sign "₱" is used in the Philippines.
The silver peso worth eight reales was also known in English as a Spanish dollar or "piece of eight" and was widely used for international trade from the 16th to the 19th century.
