What security features can you find on a commemorative banknote?
Since the design of the commemorative banknote practically corresponds to real banknotes, it also contains a number of security features that have the same function as for real banknotes - to prevent or at least significantly complicate possible counterfeiting.
The security features of the banknote are as follows:
- Valuation paper with watermark and coloured fibres
- On the reverse side: underprinted price raster, iris gradients, two-colour fluorescence under UV lamp in iris gradient, hidden pattern with initials VH
- On the reverse side: price underprint raster, iris gradients, two-colour fluorescence under UV lamp in iris gradient, pyramidal numbering with green fluorescence under UV lamp
