Dubious people cannot produce a real Naira note. That’s a fact!
Even if they finally do, they can’t produce real naira note without spending more than the amount they try to produce.
In view of this, there are always obvious differences between a real Naira notes and its counterfeits.
These differences are not hidden; they are there only if you obsvere carefully, even for a lay man.
You should also be informed that the use of counterfeits is punishable under the Nigerian constitution whether you’re aware or note because “ignorance is not an excuse in the court of law.”
Please do take note of the differences between the real and counterfeit Naira notes that I’m going to list out to identity counterfeits Naira notes.
Through The Use Mercury Bulbs
In the real paper Naira notes, there are some texts that are not visible to the naked eyes; they are only visible through the rays from a mercury bulb.
So, to verify the authenticity of these Naira notes, bring the said note in contact with rays from a mercury bulb.
If it’s real, you’ll see a greenish-yellow glow of the note’s denomination across it.
For example if it’s a ₦1000 note, you’ll see a glowing 1000 (in numbers) written across the note and smaller ₦1000 written on specific spots on it. The same goes for other paper Naira notes denominations.
If the money is in a stack or bundle and you want to test for counterfeits, arrange the monies (it should be the same denomination all-through) properly (i.e. the front of each note in the bundle in contact with the back of the next note and top to top and bottom to bottom) and subject a side of it to rays from the mercury lamp, the greenish-yellow glow should be visible on the first and last note in the bundle if no counterfeit(s) is hiding in it.
In the single note and the bundle (if properly arranged), absence of this greenish-yellow glow means the notes or a note in the bundle isn’t original.
Sorry, I couldn’t get you an image but trust me, the glow is very visible.
Make sure to switch-off other light sources so as not to hamper the result.
While mercury bulb is available at shops where electrical materials are sold, this method is preferable for business owners or people who handle huge some of cash.
Through Water or Other Liquids
The colours used in printing fake currencies are soluble in water and some other liquids while for original notes are not.
To know a fake Naira note, wet the suspected note or a part of it with water or any other liquid—I have only tried water and petrol—and scrub the wet part of the money with your thumb.
Fake Naira notes will wash-off their colours as you do this but real will not.
Do you notice the way the colours of an artwork painted with water-colours wash-off when water touches it? That’s the kind of wash-off I mean.
Through the Ribbons
On every paper money on the Naira is a thin silvery ribbon running from the top to the bottom of the note; it’s trashy on old notes.
In real note, you can feel and even pull-out this ribbon on some old notes.
However, in counterfeits, there’s something that looks like a ribbon but it’s not—just paint. Try scratching that ribbon, it come off like the silver panel on a recharge card.
Paper and Colour Quality Testing
While counterfeits are made of ordinary papers, real money is made of a special kind of paper. These kind of papers are not easy to come by and are not cost-effective.
Feeling the paper-quality of fake money, you’ll find out that it’s just like that of paper found on the streets. The colours of counterfeits also betray it.
The drawings on fake naira notes are more blurry, blotchy and sometimes darker than original paper money.
Of the four methods listed above, the first, second and third are more reliable.
