100 Dolarów Foreign Exchange Certificate

Bank Pekao's foreign exchange certificates — known in Poland as "peweksy" or "bony towarowe" — were a mechanism the communist government used to capture hard currency from Poles receiving remittances from relatives abroad. Rather than allowing free exchange, the state required dollars, deutschmarks, and other Western currencies to be converted into these certificates, redeemable only at the Pewex chain of hard-currency shops selling imported goods unavailable elsewhere in the Polish economy.

The 1979 series was printed by the Polish Security Printing Works (PWPW) in Warsaw. Certificates of this denomination circulated alongside smaller fractional values down to one cent, the full series designed to absorb remittances of any size without leaving the holder with useless change.
