Historical context
Struck in gold in 1808 and engraved by Gerónimo Antonio Gil, this medal commemorates the proclamation of Ferdinand VII in San Luis Potosí. The precious metal and the great master's signature place it among the most notable pieces of the swearing-in, reserved for the highest-ranking authorities.
The year was critical: after the Abdications of Bayonne forced by Napoleon, New Spain proclaimed Ferdinand VII king in absentia, rejecting Joseph Bonaparte as a usurper. The swearings-in of 1808 were an act of loyalty charged with political tension.
Although Gil died in 1798, his name and his dies remained tied to the Mint, whose engraving workshop he had founded; medals made from his models or under his tradition continued to be produced. That San Luis Potosí, a prosperous mining city of the highlands, commissioned a gold medal confirms its wealth and the solemn rank it wished to give its homage to the captive king.
Description
The "San Luis Potosí" medal was struck in 1808. It is made of gold, measures 40.92 mm in diameter and weighs 38.27 grams, minted in Mexico, the work of engraver Gerónimo Antonio Gil. In the specialized catalog it is referenced as Grove, Medals of México, I #F-158.
Because it is a gold medal, its value has a floor: the precious metal content (38.27 grams). Above that, what drives it up is condition, how short the issue was, and interest in the subject it commemorates (San Luis Potosí). A piece with no wear and its original case is worth considerably more than one that has been handled.
