The Bulgarian National Bank has announced that a modified 50-lev banknote will be issued from 1 November 2019. 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. Changes in the banknotes of the new series stem mainly from the introduction of new security features.
Some of the new safety features:
An additional sign for the blind: it consists of four thick and seven thin lines, angled at both short sides of the banknote.
Holographic band with optical effects: alternating images of a bird and Icarus alternate when the viewing angle changes; color hologram portrait of Pencho Slaveikov; a book that changes color from golden to green when the viewing angle changes; a dynamic flame effect with a change in color from golden to green as the viewing angle changes and a 3D image of the number 50.
Optical Effect Ink: the number 50 is printed with a color-changing, dynamic flame ink that changes from golden to green when the viewing angle is changed.
Security thread: embedded in the paper and partially protruding from the reverse with a light repeating text "BNB 50" and a dynamic flame effect changing its color from golden to green. The image of the repeated text "BNB 50" can be read from the front when the banknote is placed against a light source.
High resolution watermark: can be observed when holding the banknote against a light source. It consists of a high resolution halftone image of Pencho Slaveikov's portrait. The images can also be observed on the back of the banknote.
The Bank of England has unveiled what the new 20-pound note will look like with a press release on 10 October 2019. The new note has painter J.M.W. Turner as its subject.
Features on the new £20 note include:
A large see-through window with a blue and gold foil on the front depicting Margate lighthouse and Turner Contemporary. The foil is silver on the back. The shape of the large window is based on the shape of the fountains in Trafalgar Square.
A smaller see-through window in the bottom corner of the note, inspired by Tintern Abbey.
JMW Turner’s self-portrait, painted c. 1799 and currently on display in Tate Britain.
One of Turner’s most eminent paintings The Fighting Temeraire; a tribute to the ship HMS Temeraire which played a distinguished role in Nelson’s victory at the Battle of Trafalgar in 1805. The painting is currently on display in the National Gallery and was voted the nation’s favourite painting in a 2005 poll run by BBC Radio 4.
A metallic hologram which changes between the word 'Twenty' and 'Pounds' when the note is tilted.
The Queen's portrait in the see-through window with '£20 Bank of England' printed twice around the edge.
A silver foil patch with a 3D image of the coronation crown.
A purple foil patch containing the letter 'T' and based on the staircase at the Tate Britain.
A quote "Light is therefore colour" from an 1818 lecture by Turner referring to the innovative use of light, shade, colour and tone in his pictures.
Turner's signature from his Will, the document with which he bequeathed many of his paintings to the nation.
A special website has been launched with even more details about this beautiful new banknote: www.thenew20.co.uk. The new banknote will enter circulation from 20 February 2020.
