500 Pesos

The P#69 500 Pesos belongs to the Series C family issued through the late 1970s, a period when Banco de México was managing significant inflationary pressure following the 1976 peso devaluation — the first forced realignment of the currency since 1954. The 500 Pesos denomination, once commanding, was by 1979 a routine transaction note rather than a high-value instrument.

Banco de México printed this series in-house at its own facilities, a capacity it had developed to reduce dependence on foreign security printers. The watermark remains the sole mechanical security feature — modest by contemporary standards, even for the period.
