Look: Print Quality
Lines should be sharp and well defined with no blurred edges. Colours should be clear and distinct.

Look: Watermark
Hold the note up to the light. You should see a WATERMARK image of JB Dunlop and the word ‘ten’ to the right of his ear. The watermark is visible from both the front and back of the note.

Look: Security Thread
The SECURITY THREAD is visible as silver dashes when the note is laid flat, but when the note is held up to the light the thread becomes visible as a continuous line containing the word ‘Northern’ and runs from the top to the bottom of the note.

Look: See Through
The circular pattern to the right of the portrait with the hexagonal shape in the centre, has a white background when the note is laid on a table. But when viewed against the light, areas fill in neatly with colour from the reverse of the note forming the number '10'.

Look: Microprint
When examined closely with a good quality magnifying glass you will see:

• 'NORTHERNBANK' is written repeatedly in concentric circular patterns within the 4 corners of the note.
• 'NORTHERNBANK' is also written repeatedly along the bottom edge of the portrait.
• The letters 'NB' and the number '10' can be found in the cog wheel designs in the centre background area of the note.

Look: Serial Numbers
Each note has a unique serial number which is printed twice on the front of the note, horizontal on the upper left and vertical on the bottom right. Serial numbers for the £10 note consist of two letters followed by seven numbers. The horizontal serial number is black and the vertical is red and both increase in size with distance from the letters.

Look: Denomination Numerals
The number '10' appears in the top left and centre of the note and accompanied by a £ sign in the top right on the front of the note.

Feel: Paper Quality
The paper should feel crisp - not limp, waxy or shiny.

Feel: Raised Print
You will feel raised print if you run your finger over:

• The Northern Bank name.
• All writing including signatures.
• The denomination numerals.

Tilt: Lift Classic
If you tilt the front of the note away from you at an oblique angle and look along its breadth you will see the number '10' appear in the bottom right hand corner of the portrait on the front of the note.

Tilt: Gold Foil
If you tilt the note under the light, the GOLD FOIL beneath the £ sign in the top right-hand corner of the note shines and reflects the light.

Check: Compare
Always compare both sides of a suspect note with another note that you know to be genuine, looking for differences between the two. Make sure you check the size of a suspect note against a known genuine note.

Check: UV Fluorescence
If you place the note under a good quality ULTRA-VIOLET light, you will see highlighted on the front of the note a four-line horizontal and a four-line vertical barcode fluoresce.
