50 Nuevos Pesos

The "Nuevos Pesos" designation dates this note to Mexico's 1993 monetary reform, when the government redenominated the currency at 1,000 to 1 — a direct consequence of peso inflation that had been compounding since the 1976 devaluation and accelerated sharply through the debt crisis of the 1980s. The word "Nuevos" was dropped again in 1996 once the transition was considered stable.

Banco de México has printed its own notes in-house since the 1960s, making it one of the few central banks in Latin America to maintain that capacity continuously. The 1992 date places this among the transitional issues produced ahead of the formal redenomination announcement.
