Bulgaria announces modified 20-lev banknote

The Bulgarian National Bank has announced that a modified 20-lev banknote will be issued from 20 March 2020. The note is part of the new modified series. The overall design and main features of the new banknote remain unchanged with respect to the banknotes in circulation. The upgrade focuses primarily on new security features.

These changes are for the 20-lev banknote as follows:

Additional mark for visually impaired people – three thick and seven thin lines at an angle along the short sides of the banknote.
Hologram stripe with optical effects – alternating images of a lion and an eagle, changing when the banknote is tilted; a coloured hologram portrait of Stefan Stambolov; a stylised image of the Order of Bravery; images of a 'crowned lion rampant' with a dynamic effect and a 3D image of the number '20'.
Security thread – built into the paper and partially appearing on the reverse, with a repeated light-coloured text 'БНБ 20' (BNB 20) and a 'fan-like' dynamic optical effect shifting from green to blue. The image of the repeating text 'БНБ 20' is visible on the obverse when the banknote is held up against the light.
High resolution watermark – seen when the banknote is held up to the light. It consists of a high resolution half-tone image of Stefan Stambolov’s portrait. The image is also seen on the reverse of the banknote.
The existing 20-lev banknotes remain in circulation along with the new 20-lev banknotes.
