Mexican peso
currency of Mexico
The Mexican peso (symbol: $; currency code: MXN; also abbreviated Mex$ to distinguish it from other peso-denominated currencies) is the official currency of Mexico. The currency was first introduced in 1863, replacing the old Spanish colonial real.
Each peso is subdivided into 100 centavos, represented by "¢". Mexican banknotes are issued by the Bank of Mexico in various denominations and feature vibrant colors and imagery representing Mexican culture and history. Modern peso and dollar currencies have a common origin in the 16th–19th century Spanish dollar, most continuing to use its sign, "$". During the era of silver coinage, the Spanish dollar and the Mexican peso circulated globally in trade and as reserve currencies. They were also legal tender in the United States, Canada, and China, and served as a model for the U.S dollar and several other currencies.
The current ISO 4217 code for the peso is MXN; the "N" refers to the "new peso". Prior to the 1993 revaluation, the code MXP was used. The Mexican peso is the 16th most traded currency in the world, the third most traded currency from the Americas (after the United States dollar and Canadian dollar), and the most traded currency from Latin America.
Begin with the source’s own compact description: “Mexican peso” is currency of Mexico. The dossier treats that line as a proposition to test through Mexican, peso and currency, not as a finished interpretation.
