Since the Central Bank of Nigeria released the new naira notes into circulation, there have been complaints of fake notes that circulated the system resulting in grave concerns. However, according to the Central Bank of Nigeria, the Naira banknotes are protected by several security features to recognise genuine notes easily. The distinguishing features which can be recognised by touch and visibility are the raised print, the security thread and the watermark. The portrait, lettering and the denominational numerals on the obverse and reverse of the notes are embossed.
Look out for a slim strip To identify whether the note is fake or genuine, look for a slim-like strip that runs from the top to the bottom. This strip or thread is always present in every real paper naira note. A fake note would never have this strip but can only have what may appear to look like it.
Look out for a gold foil On the right-hand side of your note is a gold foil, right beside the signature of the CBN governor. You can test the authenticity of the note by attempting to peel the foil. If it does peel, that exposes the note to be fake because the real one doesn't peel.
