50 Pesos 'B' Foreign Exchange Certificate

Cuba's Foreign Exchange Certificate series — introduced in the 1980s to capture hard currency from tourists and Cubans receiving remittances — operated as a parallel monetary system designed to wall off dollar-equivalent purchasing power from the peso economy. The 'B' series was specifically designated for use by foreign visitors, while a separate 'A' series circulated among Cuban nationals entitled to foreign exchange. The distinction mattered: each series was redeemable only in its corresponding network of dollar stores.

Státní Tiskárna Cenin, the Czechoslovak state security printer, produced the series — a logical choice given Cuba's close economic ties with COMECON partners throughout the period.
