There are two methods to check the £50 polymer banknote for authenticity: a quick check and a much more thorough investigation of the note’s security features. We list both checks you can make on the current £50 note.

Quick check £50 polymer note

To quickly check the polymer banknotes, use these two tests:

  1. Hologram image change: Tilt the note side by side to view the hologram change from ‘note value’ to the word ‘pounds’.
  2. See-through window: In the second window at the bottom right, check the foil image is gold on the back but green on the front.

Thoroughly check the £50 polymer banknote authenticity.

Time needed: 3 minutes

Instructions to thoroughly check the security features of the £50 polymer banknote to ensure its authenticity.

  1. Check the see-through window.

    A portrait of the Queen is printed on the see-through window with ‘£50 Bank of England’ printed twice around the edge.

  2. See the foil patch.

    A silver foil patch contains a 3D image of the coronation crown above the main see-through window on the front of the note.

  3. Feel for raised print.

    On the front of the note, you can feel the raised print on the words’ Bank of England’ and in the bottom right corner, over the smaller window.

  4. Confirm the print quality.

    The printed lines and colours on the note are sharp and clear, with no smudges or blurred edges.

  5. Use a magnifying glass.

    Use a magnifying glass to see the note’s value in small letters and numbers below the Queen’s portrait.

  6. Use a UV light.

    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.

  7. View the red foil patch.

    A metallic, red foil patch contains the letters’ AT’ on the back of the note, directly behind the silver crown on the front.

By following these steps, you can verify the authenticity of the £50 Alan Turing polymer note.
