Polish 50 Złoty Banknote (1988 Issue, Karol Świerczewski series)

This is a 50 Złoty banknote issued by the Narodowy Bank Polski (National Bank of Poland). The note features a vertical orientation in this view, primarily colored in shades of olive green, yellow-tan, and light blue. The central motif depicts an stylized cross with a shield in the middle containing two swords, a symbol associated with the Grunwald Cross. Text on the bill includes 'NARODOWY BANK POLSKI' and 'PIĘĆDZIESIĄT ZŁOTYCH'. The bottom left area features a large, stylized 'NBP' monogram in a flourish-heavy cursive script. Micro-printed guilloche patterns and intricate geometric line work serve as anti-counterfeiting measures throughout the background. The paper appears to be typical banknote cotton-fiber substrate. In terms of condition, the note is encased in a plastic sleeve, which has preserved its crispness; there are no immediate signs of heavy circulation folds, tears, or staining, though a slight curvature is visible from storage. This specific design was part of the late People's Republic of Poland era (Socialist period), typically dated around 1988 before the hyperinflation and subsequent redenomination of the mid-1990s. The craftsmanship reflects the high-quality intaglio printing standards of the Polish Security Printing Works (PWPW).
