100 Zlotys Greater Poland Uprising Trial Strike

Trial strikes from the late communist period in Poland occupy a strange position in the catalog record — officially produced by the Narodowy Bank Polski for testing purposes, never released to circulation, yet clearly struck with enough care to suggest the parent issue was genuinely considered for production. The Greater Poland Uprising of 1918–19, in which ethnic Poles in the Poznań region successfully fought off German forces in the immediate aftermath of World War I, was a subject the authorities periodically found politically acceptable to commemorate, given its anti-German rather than anti-Soviet framing.

The nickel composition here distinguishes this trial from the issued commemorative versions. Fischer and ParM references both classify it firmly as a probe, not a pattern with altered design.
