1 Peso

The .720 silver standard used for this peso was a deliberate reduction from the previous .903 fine coinage, reflecting Mexico's need to retain silver for export revenue during a period when the metal commanded premium international prices. The change came as the country was still absorbing the economic wreckage of a decade of revolution.

During World War II, U.S. demand for Mexican silver to support war production drove enormous quantities of circulating coinage into the melting pot — a fate that claimed a disproportionate share of the earlier dates in this run.
