Poland - P-145c - 500 Zlotych - Foreign Paper Money

Foreign Paper Money. T. Kosciuszko portrait/Arms and flag. The złoty (PLN) is the official currency and legal tender of Poland. It is subdivided into 100 grosz (gr). It is the most traded currency in Central and Eastern Europe and ranks 21st most-traded in the foreign exchange market.

The word złoty is a masculine form of the Polish adjective 'golden', which closely relates with its name to the guilder whereas the grosz subunit was based on the groschen, cognate to the English word groat. It was officially introduced to replace its predecessor, the Polish marka, on 28 February 1919 and began circulation in 1924. The only body permitted to manufacture or mint złoty coins is Mennica Polska, founded in Warsaw on 10 February 1766. Read more at https://en.wikipedia.org/wiki/Polish_z%C5%82oty
