Royal Mint Unveils Prototype One Pound Coin To Reduce Counterfeiting

The Royal Mint revealed today (19th March) that they will propose to issue a new £1 coin with state of the art security features which are being incorporated in the new coin in an effort to reduce the significant amount of counterfeit coins.

The Chancellor or Finance Minister of the United Kingdom, George Osbourne has announced that HM Treasury believes there is a strong case for introducing a new £1 coin to help reduce counterfeiting and ensure the integrity of the United Kingdom’s currency. Mr. Osbourne commented, “The Royal Mint has developed world-leading anti-counterfeiting technology which will enable Her Majesty’s Treasury to modernize the United Kingdom’s circulating currency with the production of a brand new £1 coin”

Prototype One Pound Coin

The use of iSIS, The Royal Mint’s new Integrated Secure Identification System offers a fully protected currency system based on a new generation of coin, which incorporates three tiers of covert banknote-strength security and can be authenticated via high-speed automated detection units to industry-leading levels, including retail and vending equipment. Project iSIS is the work of The Royal Mint’s in-house technology team and involves the application of an existing security technology that has been proven over decades in banknotes. It is the first time that this existing security has been successfully embedded into coins.

The prototype coin which is proposed would incorporate micro-text along the coin’s surface edge and rim. The actual side edge also sees the addition of improved incused lettering which would incorporate micro-texture on the actual letters. The prototype coin produced by the Royal Mint proposes a twelve-sided shape which evokes memories of the pre-decimalization brass three-pence piece. It will be constructed from two different colored metals (bi-metallic) and contain an iSIS security feature.


As part of the Royal Mint and the Treasury’s program to introduce a new generation one pound coin, a public consultation will be held over the summer focusing on how to manage any impacts before a final decision is made on the precise specification of the new coin, including the metal composition. The Royal Mint proposes to work closely with key industry stakeholders to conduct a full consultation in order to understand the potential impact for industry.  It was also announced that a public design competition will be held at a later date to choose the design for the reverse side of the coin which is expected to be introduced in 2017.

Over the last decade, there have been consistent calls by cash handlers and the public to increase the security of the one pound coin – in circulation in the United Kingdom since 1983. It is estimated that at any time, there are more than 35 to 40 million counterfeit coins of the more than 1.5 billion one pound coin denominations in circulation. Other estimates claim that out of 1000 pound coins in circulation, between 31 to 38 of those coins are counterfeit. The Royal Mint also utilize the one pound coin’s reverse design for various series’ which highlight the four constituent countries within the United Kingdom and including flora, bridges, heraldry and coats of arms.  To date, the one pound coin has been issued with a total of 21 different reverse designs.

    Well, I think you may find in the future, a similarly shaped coin in the EURO-zone with a five euro denomination – I do not have any insight on the subject but I think if it were to be introduced, which several European Central Banks would be in favour of – this is a possible way of making this coin distinctly different from the round coins currently in circulation.

    When does 5 euro coins in the shape of dodecahedron would be in circulation in euro zone?

  3. M Alexander says

    Currently, there are no publicised plans from the European Central Bank to introduce a five euro coin throughout the Euro-zone as the ECB are committed to the circulation of the present five euro banknote introduced into circulation last year.
    But, as the value of the €5 note lessens with minimal inflation and the quality control of the paper notes becomes greater, it may be that the only alternative for this denomination would be a coin.
