2000 Zlotys Duke Mieszko I half length, Trial Strike

This trial strike dates to a period when the Polish State Mint was actively developing high-denomination commemorative designs celebrating the Piast dynasty — a deliberate state project to anchor the People's Republic's legitimacy in medieval Polish statehood. Mieszko I, the tenth-century duke who accepted Christian baptism in 966 AD and is considered the founder of the Polish state, was a recurring subject precisely because his reign predated any ideologically inconvenient associations.

The ParM and Fischer references confirm this as a documented proof-of-concept piece, one of several parallel trial compositions struck before the final authorized issue was approved.
