Characteristics of the 10 złoty banknote

Description of modernised 10 złoty banknote

The 10 złoty banknote features a portrait of Prince Mieszko I. On the left-hand side of the portrait there are two rosettes inspired by the pattern found on the floor of Gniezno Cathedral, whereas on the right-hand side there is a floral motif found on Romanesque liturgical vessels.

On the reverse side there is a denarius – a silver coin depicting the image of the dome of a chapel or a crown with a cross. On both sides of the denarius there are stylized Romanesque columns from the Benedictine Abbey in Tyniec.

Characteristic elements of the modernised banknote:

  • banknote size: 120 x 60 mm,
  • Watermark showing value numeral may be seen against the light in the field free from print (1),
  • Turquoise-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 Governor and the NBP General Treasurer are in raised print, which is easy to feel, also for the visually impaired.


When you examine the banknote against the light the watermark depicting the sovereign and the value numeral “10” 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 “10” 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.

Iridescent strip

On the reverse side of the banknote there is a turquoise-coloured strip with the value numeral “10” 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.

Latent image

A light or dark value numeral “10” appears in a single latent image when tilting the banknote– depending on the angle that the note is held at.


Tiny inscriptions made with high precision in offset or intaglio printing techniques. The smallest inscription on the banknote should be sharp and readable when magnified.

Banknote under UV-light

A square with the value numeral “10” and symbol “ZŁ”, the banknote serial number and other selected elements appear under UV light.
