Police in Derry have issued a warning to businesses after getting reports of counterfeit notes circulating in the city.
As a result, police have issued a checklist for staff to carry out.
Does the main printing feel raised?
Can you see a bold and clear watermark when the note is held up to the light?
Does the note feel crisp and not limp, waxy or shiny?
Is the print clear, sharp and well defined?
Are the colours clear and distinct? Compare the suspect note against a note which is known to be genuine.
Is the security thread continuous when the note is held up to the light?
