The second award winner was Narodowy Bank Polski for the 20 zloty commemorative banknote, dedicated to the famous Polish astronomer, economist and mathematician Nicolaus Copernicus, marking the 550th anniversary of his birth, and the 480th anniversary of his death.
The note was produced by the Polish Security Printing Works (PWPW) on CCL Secure’s GUARDIAN™ substrate, and 100,000 were issued by the National Bank of Poland in February 2023.
Its design is a dynamic celebration of the life and work of Copernicus, with his portrait depicted alongside several security features which are embedded into the substrate. They include a large transparent blue window containing CCL Secure’s Cinema™ feature, which shows multiple images of the earth rotating around the sun, paying homage to the astronomer’s groundbreaking heliocentric theory.
The feature is complemented by a clear transparent window containing a yellow spot colour, vignette line work and shadow images, providing further depth and movement and historical context to the other planets orbiting the sun (ie. the heliocentric system).
An additional smaller window includes a VIVID™ Colour feature representing the solar system. In daylight the feature is a white, photographic-like image of the solar system, but under UV light it is fully coloured. An iridescent stripe is an additional security feature that complements the image of old coins decorating the reverse of the note, representing Copernicus’ formulation of the quantitative theory of money.
