1000 Zlotys National Schools Aid Action, Trial Strike

The National Schools Aid Action — known in Polish as Społeczny Fundusz Budowy Szkół — was a state-organized fundraising initiative through which Polish citizens contributed to school construction across the country. By the mid-1980s it had become a vehicle for commemorative numismatics, with the NBP issuing related pieces tied directly to the campaign. Trial strikes in nickel from this program were produced for internal approval purposes and rarely escaped the mint in any quantity.

The Fischer reference Po#P325a distinguishes this from at least one parallel trial variant, suggesting multiple composition or finish tests were conducted before a production decision was made.
