All of our polymer notes can be checked using the same two security features
Tilt the note from side to side. Check the words change between ‘Fifty’ and ‘Pounds’.
Look at the metallic image over the main window. Check the foil is gold and green on the front of the note and silver on the back. Within the two gold foil squares on the front of the note, the images change between ‘50’ and a ‘£’ symbol when the note is tilted.
Look for a second, smaller window in the bottom corner of the note.
The Queen’s portrait in the see-through window
A portrait of the Queen is printed on the window with ‘£50 Bank of England’ printed twice around the edge.
Silver foil patch
A silver foil patch contains a 3D image of the coronation crown. You will find this above the main see-through window on the front of the note.
Red foil patch
A metallic, red foil patch contains the letters ‘AT’. You will find this on the back of the note, directly behind the silver crown on the front of the note.
Feel of polymer and raised print
The note is printed on polymer, which is a thin and flexible plastic material. On the front of the note, you can feel raised print. For example, on the words ‘Bank of England’ and in the bottom right corner, over the smaller window.
Print quality
The printed lines and colours on the note are sharp, clear and free from smudges or blurred edges. If you use a magnifying glass, you will see the value of the note written in small letters and numbers below the Queen’s portrait.
Ultraviolet number
Under a good-quality ultraviolet light, the number ‘50’ appears in bright red and green on the front of the note, against a duller background.
