The Bulgarian National Bank (BNB) says it is putting a new version of the BGN 5 banknote with enhanced security features in circulation on 4 September.

The BNB says the overall design and the main elements of the banknotes of the new series feature no significant changes as compared to the banknotes already in circulation.

The Sofia Globe reports the security features include:

  • An additional mark for visually impaired people – one thick and nine thin lines at an angle along the short sides of the banknote.
  • Hologram stripe with optical effects – images of a woman reaper and a stylised flower alternating when the banknote is tilted; а coloured hologram portrait of Bulgarian painter Ivan Milev; images of a “crowned lion rampant” with a dynamic optical effect and a 3D image of the number 5.
  • Security thread – built into the paper and partially appearing on the reverse with a repeating light-coloured text ‘БНБ 5’ (BNB 5) and a vertical dynamic optical effect shifting its colour from red to green. The repeating text ‘БНБ 5’ is visible on the obverse when the banknote is held up to the light.
  • High-resolution watermark – seen when the banknote is held up to the light. It represents a high-resolution half-tone portrait of Milev. The image is also visible on the reverse of the banknote.

The BNB says the old BNB 5 banknotes – issued in 1999 and 2009 – will remain in circulation along with the new BNB 5 notes.
