Casa de Moneda de San Luis Potosí Medal (1887)

The San Luis Potosí Mint was one of the provincial mints that operated in Mexico during the 19th century. In an era of scarce currency and difficulties transporting silver, several mining and commercial cities struck their own coinage under official authorization.

This 1887 bronze medal commemorates that Potosino institution. San Luis Potosí was an important mining and transit hub, and its mint was part of the infrastructure that sustained the circulation of Mexican silver, famous throughout the world.

Engraved by A. Flores G., the piece is doubly valuable for numismatics: it commemorates a mint while also being a product of the official medal-making tradition itself. It is testimony to the role of the provincial mints in Mexico's monetary history.

The "Casa de Moneda de San Luis Potosí" medal was struck in 1887. It is made of bronze, measures 43.71 mm in diameter and weighs 28.87 grams, the work of the engraver A. Flores G.. In the specialized catalog it is referenced as Grove, Medals of México, II #245b.

As a bronze medal, its value comes not from the metal but from the commemorative side: the event it celebrates, its age (1821-1910 era), and demand among collectors of the subject. Condition and the rarity of the issue are what set the price.
