What are the anti-counterfeit measures on a £1 coin?

According to the Royal Mint, the current £1 coin is being replaced for the first time in over thirty years because of its vulnerability to sophisticated counterfeiters. It says approximately one in thirty £1 coins currently in circulation is a counterfeit.

Here’s a guide to some of the key features on the new coin that make it much more difficult to counterfeit:


The new coin’s bimetallic design, which is made up of silver nickel-copper surrounded by gold nickel-brass, makes it much harder to copy than the old pound coin.

Latent image

On the heads side of the coin there is a latent image like a hologram. When seen from one angle it shows the ‘£’ symbol while from another angle the number ‘1’ appears.


Very small lettering on the lower inside rim on both sides of the coin is designed to make life difficult for counterfeiters.

Milled edges

The new £1 coin has grooves on alternating sides of the 12 sides of the coin -again this addition makes it extra tough to copy.

Hidden high security feature

Intriguingly, the Royal Mint says the new £1 coin also has a hidden security feature, which it has given very little details of.

It has been reported that a machine is required to detect this feature, which is reportedly currently impossible for those counterfeiting coins to copy.
