La Casa de Moneda de México is the national mint of Mexico and is the oldest mint in the Americas. The Mexican Mint was established in 1535 by the Spanish viceroy Antonio de Mendoza by a decree from the Spanish Crown to create the first mint in the Americas. The mint's silver eight-real coins and its successor coin, the silver peso, circulated widely in the Americas and Asia well into the 19th century and became the basis of the modern national currencies of many countries in these parts of the world, including the United States dollar, the Japanese yen and the Chinese yuan .
