10, 20, 50, 100 and 200 PLN banknotes, used as legal tender in modern Poland, were put into circulation in the first half of 1995, as a result of currency reform. For the first two years, the money designed by Andrzej Heidrich was printed in London and then the production was taken over by the Polish Security Printing Works in Warsaw. A few years ago, improved security features were introduced, thanks to which new series of banknotes are more difficult to forge. On February 10, 2017, a 500-zloty banknote with the image of king Jan III Sobieski was officially published.
