El cambio en el sistema monetario de Japón y el peso mexicano en un expediente del Archivo Histórico Nacional de España de 1871

This article examines the important Japanese mo-netary reform of the year 1871, for which Japan was endowed with a currency according to Western models. This reform, based on the gold standard, could not be alien to the current trade flows in Asia and the Pacific area, based on the silver coin and especially in the Mexican peso, so it retained the emissions of yen milled in silver for the commerce with the foreign powers. This study incorporates a document preserved in the Archivo Historico Nacional of Madrid, which shows the importance that in the trade had the Mexican currency of silver.
