Three years and £2 million in the the making, it uses technology already used in banknotes that allow its authenticity to be established incredibly quickly with a simple scan.

At the heart of the new design is the catchily titled Integrated Secure Identification Systems (iSIS), embedded into the heart of the coin.

The new one pound coin

For obvious reasons the full details of iSIS are unavailable as are the exact make-up of the materials used to make it.

The coin's 12-sided shape is its first line of defence as to replicate this is much harder that a simple circle.

Additionally, the Royal Mint, who developed the coin, use a process called aRMour full-plate technology in their production process.

This process applies a single layer that is electroplated directly onto a steel core which results in a very strong bond between the plated material and the steel core.

What the coin's makers will tell us is the myriad of benefits the system can achieve...

  • It will reduce costs by replacing expensive clad and homogeneous coins with a more affordable full-plated option.
  • It will generate lifetime cost savings through unmatched durability, lasting up to 30 times longer than an equivalent value banknote.
  • It will have considerably lower replacement frequency than other plated coin types.
  • Both robust and secure, its issuance protects the reputation of a country, projecting a positive image of the nation and its economy.
