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

Cuba's Foreign Exchange Certificates were a parallel currency system introduced to capture hard currency from tourists and foreign workers while keeping it out of the general peso economy. The "D" series — distinguished by an overprinted or incorporated "D" designator — was restricted to socialist-bloc visitors, a deliberate two-tier arrangement that separated capitalist-source dollars from funds arriving via COMECON channels. Whether that distinction was rigorously enforced at the point of exchange is another matter entirely.

Státní Tiskárna Cenin in Prague printed much of Cuba's paper currency output during this period, a natural arrangement given the political alignment. The FX certificate series as a whole was abolished in 1989, meaning the circulating life of these notes was short.
