5 Pesos 'C' Foreign Exchange Certificate-Round 'C'

Cuba's Foreign Exchange Certificates were a parallel currency system designed to capture hard currency from tourists and diplomats while keeping it out of ordinary circulation. The "C" series — distinguished by an overprinted or incorporated round "C" device — circulated alongside, but strictly separately from, the peso convertible system that came later. Tourists were legally required to exchange foreign currency into these certificates; spending pesos alongside Cubans in the same peso economy was not the point.

Státní Tiskárna Cenin in Prague printed Cuban currency throughout much of the Cold War period, a natural arrangement given the bilateral trade agreements between Cuba and Czechoslovakia after 1960.
