Modernised banknotes - 20 zł
The 20 zloty note features a portrait of King Boleslaw I the Brave. On the left-hand side of the portrait there is a Romanesque portal, whereas to the right-hand side there is a treetop of a young oak taken from the Gniezno Doors, namely from the scene of St. Adalbert’s remains being laid in state.
On the reverse side there is a denarius – a silver coin struck under Boleslaw I the Brave depicting the silhouette of a bird and the inscription PRINCES POLONIE. On the left-hand side there is an image of St. Nicolas in Cieszyn, whereas on the right-hand side a fragment from the door of Gniezno Cathedral – a lion stretched against a rope.
Characteristic elements of the modernised banknote:
- banknote size: 126 x 63 mm
- Watermark showing value numeral may be seen against the light in the field free from print (1)
- Lilac-coloured iridescent strip (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 2017 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 “20” can be seen.
The watermark field is free from print.
When you hold a banknote against the light, a dark vertical line with the value numeral “20” 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.
On the reverse side of the banknote there is a lilac strip with the value numeral “20” and “ZŁ” symbol. The strip becomes visible depending on the angle at which the banknote is viewed.
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.
A light or dark value numeral “20” 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.
