1000 Pesos

The P#81 series was issued during one of Mexico's most severe economic contractions — the peso had lost roughly half its value against the dollar by 1982, and inflation remained above 60% annually through the mid-1980s. A 1000-peso denomination that would have seemed substantial a decade earlier was, by 1984, barely enough for a bus fare and a meal. The note circulated hard and fast.

Banco de México retired this series quickly as inflation continued to erode purchasing power, paving the way for higher denominations that followed within a few years and ultimately the 1993 redenomination that lopped three zeros off the currency entirely.
