Poland issues new 500-zlotych note

The Narodowi Bank Polski (National Bank of Poland) has issued its new 500-zlotych banknote with the image of King Jan III Sobieksi (1629-1696) on it. This is the latest addition to the 'monarchs' series and is designed by Andrzej Heidrich who also designed the other denominations in this series. This banknote is the highest denomination in Poland.

From the press release: "The 500 zloty banknote has some of the most advanced security features in the world. The security features include a windowed security thread, colour-shifting ink and iridescent ink as well as a recto verso element (the graphical elements on both sides of the banknote align in transmitted light), a lobster-tailed pot helmet and windowed security thread (which change colour when tilted), and a watermark visible against the light (presenting a portrait of the king and the value numeral)."
