£50 GBP note & bill

Bank of England  first issued our current £50 note in 2011. It features the entrepreneur Matthew Boulton and the engineer James Watt. The £50 is our highest value note.

Size

The higher the value of a note, the larger it is. This note is approximately 156mm x 85mm.

Unique numbering

A unique serial number is printed horizontally and vertically on the back of the note. The horizontal number is in the bottom right corner. It is made up of multi-coloured letters and numbers, which increase in height from left to right. The vertical number runs down the left-hand side and the numbers and letters are the same height and colour.

Copyright symbols

The international copyright symbol is included on the front of the note, to the left of the motion thread and on the back, below the ‘James Watt 1736 – 1819’ text.

Historical characters

Boulton was an entrepreneur, while Watt was an engineer and scientist who made revolutionary changes to the efficiency of the steam engine. In 1775, the two formed a partnership to develop and market steam engines, and the designs were taken up worldwide. The metric unit of power is named after James Watt.

Artwork

There is an image of the Soho Manufactory in the background - a factory used mainly to build machinery. The design was taken from a drawing produced in 1781. The steam engine design at the front of the note was taken from the Whitbread Engine, built in 1785 by the Boulton & Watt company.

Quotes

‘I sell here, Sir, what all the world desires to have - POWER' and 'I can think of nothing else but this machine' are quotes provided by the Birmingham Museum & Art Gallery.  They were on display at the Thinktank Birmingham Science Museum.

You will be able to use the paper £50 note until we withdraw it from circulation. We will announce the withdrawal date after we have issued our new polymer £50 note.

Key security features

Focus on these two key security features to help confirm that your notes are genuine.

Motion thread image change

Tilt the note up and down or side to side.  Check the images change between a '£' symbol and the number '50'.

Bright '£50' in the watermark

Hold the note up to the light.  Check there is a bright ‘£50’ at the top of the Queen’s portrait.

Other security features

Feel of paper and raised print

The note is printed on special paper that gives it a unique feel.  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, around the number '50'.

Ultraviolet features

Under a good quality ultra-violet light, the number '50' appears in bright red and green on the front of the note, against a duller background. You can see bright red and green flecks on both the front and back of the note. The motion thread also appears bright green.

Metallic thread

There is a fully embedded metallic thread in the note.  It appears as a continuous dark line when you hold the note up to a light.

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.

See-through register

Coloured shapes are printed on the front and back of the note, below the signature of the Chief Cashier. These shapes combine to form a '£' symbol when the note is held up to the light.
