Nicaragua Unfiltered

The Second Córdoba lasted just two years — 1988 to 1990. It replaced the First Córdoba at a rate of 1,000 to 1, then itself collapsed so completely that it was replaced by the Gold Córdoba at 1,000,000 to 1. This note — a 1,000,000 Córdoba overprint on a 1,000 Córdoba base note — is a physical artifact of that collapse: the government literally stamped a new denomination over the old one rather than printing fresh notes.

Augusto César Sandino on the front was assassinated in 1934 by the National Guard on orders from Anastasio Somoza García — the man who then founded the dynasty the Sandinistas overthrew 45 years later. The Sandinistas named themselves after the man their enemies murdered.

The scene on the reverse — the Liberation of 19 July 1979 — depicts the moment Sandinista columns entered Managua after Somoza fled to Miami. It was one of the most celebrated revolutionary moments in Latin American history. By the time this overprinted note was issued in 1990, the Sandinistas had just lost the election and were handing over power. The note commemorates their greatest triumph and was printed in their final months in office.

A Stamp Over a Collapsing Currency

The overprint technique tells the whole story. When inflation moves faster than printing presses, you don’t reprint — you stamp. The Nicaraguan government took existing 1,000 Córdoba notes and overprinted “1,000,000” on them, multiplying the face value by 1,000 without issuing new paper. It was a practical solution to an impossible situation: the Second Córdoba had lost 99.9% of its value in two years. The overprint is the scar tissue of hyperinflation.

Sandino, the Man Who Became a Movement

Augusto César Sandino (1895–1934) led a guerrilla campaign against US military occupation of Nicaragua from 1927 to 1933 — one of the first successful anti-imperialist insurgencies in Latin American history. He was never defeated militarily. When the Americans left, he agreed to peace talks and was invited to dinner by the new government. He was ambushed and shot on the way home. His killer’s family ran Nicaragua for the next four decades. The movement that eventually overthrew them took his name.

Own This Document of Revolution and Collapse

The P-164 is one of the most historically layered banknotes in the Americas: a martyred guerrilla leader on the front, a revolutionary triumph on the back, a hyperinflationary overprint across the face, and a currency that ceased to exist within months of issue. In UNC condition, the overprint is crisp and the base note still sharp beneath it.

The stamp says one million. The economy said it was worth less than a cent.
