10 000 Cordobas overprinted on 10 Cordobas

Nicaragua's inflation in the late 1980s was severe enough to make reprinting impractical — the government simply overprinted existing low-denomination stock rather than commission new designs. This 10,000 Córdobas on 10 Córdobas note is a direct artifact of that emergency, issued as the Sandinista administration struggled with an economy distorted by the U.S. trade embargo and the costs of the Contra war. Annual inflation peaked above 30,000 percent in 1988.

The overprint series was short-lived. The entire Córdoba was replaced by the Gold Córdoba in 1990 at a rate of 1 new unit to 1,000,000 old ones.
