5 Zlotys Nike, Trial Strike B Date between tail

The Nike 5 Złoty was designed by sculptor Józef Gosławski and introduced as Poland sought to stabilize its currency following the hyperinflationary chaos of the early 1920s. Trial strikes in bronze were produced at the Warsaw Mint to test die alignment and striking pressure before committing to the silver production run. The "B between tail" designation refers to the mint mark position variant recorded among the proof and pattern documentation — a detail that distinguishes die states rather than mint facilities, as Warsaw handled the entire issue.
