100 Pesos Baja California Sur

Baja California Sur was the last of Mexico's 31 states to be formally recognized, achieving statehood only in 1974 after decades as a federal territory — a isolation reinforced by the fact that no road connected the peninsula to the Mexican mainland until the Transpeninsular Highway opened that same year. This coin belongs to the long-running "Estados de la República Mexicana" series, which ran from 2003 to 2007 and cycled through all 31 states plus the Federal District.

The .925 silver centres in this series were produced in sufficient quantities that circulated examples are genuinely uncommon — the bullion value alone discouraged everyday use from the outset.
