50 Pesos

The P#49 series spans an unusually long production run — over two decades — reflecting a period when Mexican monetary policy leaned heavily on the ABNC for security printing, a relationship dating to the 1920s that gave the company near-exclusive access to the Banco de México's higher denominations through mid-century. The 50 Peso denomination occupied a genuinely useful position in everyday commerce during this period; Mexico's postwar industrialization pushed real wages just high enough that 50 Pesos circulated hard.

Heavily circulated examples are the norm, not the exception. Notes from the early 1950s show the most wear — the 1954 peso devaluation, which fixed the rate at 12.50 to the dollar, pushed paper money through more hands more quickly as prices adjusted upward across the economy.
