100 Zlotys Tadeusz Kościuszko, Trial Strike

Trial strikes from Mennica Państwowa in the 1970s occupy an awkward institutional space — produced for internal approval and distribution to select officials, they were never meant to enter commerce yet consistently surface in specialist collections. This particular piece was part of a broader Polish commemorative program that used Kościuszko's image repeatedly across denominations during the decade, a reflection of the PZPR's careful curation of historical figures deemed safe enough to celebrate under socialist rule — revolutionary, anti-tsarist, and conveniently admired in the United States, where Polish diplomatic optics still mattered.

The .625 silver alloy used here differs from the fineness adopted for the final circulation issue, which is the detail that places this firmly in proof-of-concept territory rather than as a presentation piece.
