5 Pesos, P-78a. The Cuban peso (in Spanish peso cubano, ISO 4217 code: CUP) also known as moneda nacional, is the official currency of Cuba. The Cuban peso historically circulated at par with the Spanish-American silver dollar from the 16th to 19th centuries, and then at par with the U.S. dollar from 1881 to 1959. The Castro government then introduced the socialist planned economy and pegged the peso to the Soviet ruble.
