The Bank of England £20 paper banknote. This film will run through a number of key security features. You should check these features to ensure notes are genuine. The foil strip on the note has a number of patches along its length which contain alternating holographic images. Positioning of the patches can vary slightly from note to note. When you tilt the note from side to side one holographic image flips between a £ symbol and the number 20. The other shows a multi-coloured image of the economist, Adam Smith. The number 20 is also embossed on the strip just to the right of the signature of the Chief Cashier. When the note is held up to the light there is a bright ‘£20’ next to the Queen’s portrait in the watermark. These banknotes are printed on special paper that gives them their unique feel. By running your fingers across the front of the note you can feel raised print in areas such as the words ‘Bank of England’ and in the bottom right corner around the number 20. If you look at the front of the note under a good quality ultra-violet light, the number 20 appears in bright red and green whilst the background remains dull in contrast. Randomly spread bright red and green flecks are also visible on both the front and back of the note. There is a metallic thread embedded in the note. This appears as silver dashes on the back and when held up to the light, appears as a continuous dark line. Also when held up to the light, you will see coloured irregular shapes printed on the front and back that combine to form the £ symbol. The printed lines and colours on the note are sharp, clear and free from smudges or blurred edges. Using a magnifying glass, look closely at the lettering beneath the Queen’s portrait. You will see the value of the note written in small letters and numbers. The £20 paper banknote.
