200 Zlotys Kazimierz I Odnowiciel, Trial Strike

Poland's 200-złoty collector series of the late 1970s and early 1980s documented the Piast dynasty rulers in sequence, and Kazimierz I Odnowiciel — the Restorer — was an obvious inclusion: he reconstituted the Polish state after the catastrophic pagan uprising of 1034–1039 that burned churches, expelled clergy, and collapsed central authority so thoroughly that he had to rule initially from exile in Germany. The trial strike designation here indicates a pre-production piece, almost certainly produced for internal mint approval or submitted to the National Bank of Poland for authorization before the standard .625 silver business strikes were authorized.

The .750 fineness distinguishes this from the issued version and points to an early metallurgical test rather than a later presentation piece.
