Mexican Peso - Use Outside Mexico

Use Outside Mexico

The Spanish dollar or Mexican peso was widely used in the early United States. By a decree of July 6, 1785, the value of the United States dollar was set to approximately match the Spanish dollar, both of which were based on the weight of silver in the coins. The first U.S. dollar coins were not issued until April 2, 1792, and the peso continued to be officially recognized and used, along with other foreign coins, until February 21, 1857. In Canada, it remained legal tender, along with other foreign silver coins, until 1854 and continued to circulate beyond that date. The Mexican peso also served as the model for the Straits dollar, the Hong Kong dollar, the Japanese yen and the Chinese yuan. The term Chinese yuan refers to the round Spanish dollars, Mexican pesos and other 8 reales silver coins which saw use in China during the 19th and 20th century. The Mexican peso was also briefly legal tender in 19th century Siam, when government mints were unable to accommodate a sudden influx of foreign traders, and was exchanged at a rate of three pesos to one Thai baht.
