10 Pesos San Luis Potosí - Silver Proof Issue

Part of a long-running series celebrating Mexico's states, this issue honors San Luis Potosí — a region whose silver mining history is inseparable from the colonial-era mint economy that funded the Spanish crown for two centuries. The Real de Catorce and Cerro de San Pedro deposits made the state one of the most productive sources of monetary metal in the Western Hemisphere.

KM#687 is among the more accessible issues in the series, with proof mintages typically distributed through Banxico's collector programs and international numismatic distributors.
