500 Zlotys Euro 1988

Issued as part of Poland's "Road to Euro" collector series, this 1987-dated piece denominated in a currency Poland would not adopt — and still has not — reflects the optimism of late-communist economic planners who genuinely believed EC monetary integration was an imminent reality for Eastern Bloc reformers. The series was produced for hard-currency export sales, generating foreign exchange for the Polish state rather than circulating domestically.
