50 Dollars Foreign Exchange Certificate

Polska Kasa Opieki — Pekao — was established in 1929 specifically to capture hard currency remittances sent by Polish emigrants abroad, primarily from the United States. By 1960, that original mandate had been repurposed entirely by the communist government: the Foreign Exchange Certificates (bony towarowe) became a mechanism for extracting dollars from Poles who received them from relatives in the West, funneling that hard currency into state coffers while giving recipients access to otherwise unobtainable imported goods at the Pewex retail network.

The system was quietly coercive. Dollars received through the post were often automatically converted into these certificates by postal authorities before the recipient ever saw the cash. Refusing the exchange was not a practical option for most.
