Modernised banknotes - 50 zł

Modernised banknotes:

The 50 zloty banknote features the portrait of King Casimir III the Great. On the right, there is a crowned letter “K”, taken from the King’s monogram on the door to the Wawel Cathedral; in the background - a Gothic ornament.

The reverse side features an image of the White Eagle from the seal of King Casimir III the Great and his regalia: the sceptre and the orb. The background presents a panorama of Kraków and Kazimierz taken from the wood engraving by Hartmann Schedel, a German traveller from the end of the 15th century.

Characteristic elements of the modernised banknote:

  • banknote size: 132 x 66 mm
  • Watermark showing value numeral may be seen against the light in the field free from print (1)
  • Letter “K”, smoothly changing colour from green to blue (3)
  • In an oval – a crown, the complete image of which can be seen when the banknote is held against the light (4)
  • Face value, portrait of the sovereign, emblem of the Republic of Poland and the signatures of the NBP President and the NBP General Treasurer are in raised print that is easy to feel, also for the visually impaired.
  • Since 2018 the banknotes introduced into circulation have a thin protective coating to make them more durable.

More developed watermark
When you examine the banknote against the light the watermark depicting the sovereign and the value numeral “50” can be seen.
The watermark field is free from print.
Security thread
When you hold a banknote against the light, a dark vertical line with the value numeral “50” and the currency abbreviation “ZŁ” is visible. Both features are legible in a mirror as well. The typeface of the microlettering has been modified. The security thread has been incorporated in the paper substrate.
The royal letter changing colour (colour-shifting ink)
As you change the angle at which you look at the banknote, the colour of the “K” letter smoothly changes from green to blue.

See-through register (recto-verso)
When the banknote is held against the light, the elements of the graphic design printed on each side combine perfectly to form a complete image – a crown in an oval.

Latent image
A crown or the value numeral “50” appears in a single latent image when tilting the banknote – depending on the angle that the note is held at.

Microlettering is writing visible only with the use of magnification that was printed both on the front and on the reverse side of the banknote.

Banknote under UV-light
A square with the value numeral “50” and symbol “ZŁ”, the banknote serial number and other selected elements appear under UV light.
