The San Luis Potosí mint

Juan Nepomuceno Sanabria was a polymath. As well as being the first assayer of the San Luis Potosí mint, he was also a professor of "medical surgery" and had knowledge of architecture. He was responsible for the Cañada de Lobo aqueduct that in 1831 brought drinking water to the city. Sanabria was not paid for his work but was awarded a gold medal in the reverse of which read: "For his philanthropy, working gratuitously to supply water to the City (Por su philantropía, trabajando gratuitamente para surtir el agua a la Ciudad)”.He had in his heart “a great, generous, feeling that never stops within the petty limits of private interest."

In 1835 Sanabria wrote an article about the Mexican mints, in response to one published in a Mexico City newspaper in 1830. Sanabria, contrary to what was stated in the earlier article, defended the idea that mints served the federation. “When the states created their own mint,” he wrote, “the prices of silver increased because the coinage process became easier and numerous abuses disappeared, mining activity was protected, and the ambition of silver speculators was played down. Further along in his article, Sanabria addressed the extraction of capital from the country. He wrote that the nation was affected if the silver were exported in bullion form and not minted:
How would the nation be affected, someone would ask, if the bullion is exported even though it has paid the taxes established in the law? I consider many bad things may happen; the process of coining silver needs machines, arms, and many other things such as copper, lead, coal, wood, etcetera. The poorest people residing in the state and the workers of the mint benefit from the marketing of these raw materials. If the mint were to be closed, five hundred families consuming clothing, foodstuffs, and the like everyday would abandon the city which would be a blow to the base of the prosperity of the state."^{Gaceta del Gobierno del Departamento de San Luis Potosí, Núm. 28, 8 July 1838}
