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

Cuba's Foreign Exchange Certificate system was introduced in 1981 to capture hard currency from tourists and exile remittances while keeping it segregated from the peso economy used by Cuban nationals. The "C" series — distinguished by an overprinted letter on earlier certificate designs — circulated in the dollar-equivalent tourist economy: hotels, diplomacy shops, and the network of tiendas recaudadoras de divisas. Holding one as a Cuban citizen without authorization was a criminal matter.

Státní Tiskárna Cenin in Prague printed Cuba's banknotes and certificates throughout the socialist period, a relationship that outlasted the Soviet Union itself.
