On October 12, 2023, The Royal Mint revealed the new designs for circulation coins during King Charles III's reign. These designs, spanning from one penny to two pounds, showcase Britain's natural habitat and wildlife, reflecting the King's strong commitment to conservation. The coin denominations, compositions, weights, and sizes remain unchanged.


Depicts King Charles III’s effigy, surrounded by the Latin inscription. Engraver's initials on the neck.

The 2023 coins issued in the Brilliant Uncirculated & Proof sets featured a special Tudor crown privy mark.

CHARLES III DEI GRATIA REX FIDEI DEFENSOR means King Charles III, by the Grace of God King, Defender of the Faith.

Engraver: Martin Jennings (MJ)



Depicts a red squirrel on the right, the denomination and an interlocked C, reminiscent of King Charles II's royal cypher, on the left side.

Red squirrels, primarily located in Scotland (75% of their population), can also be found in Northern Ireland, the Isle of Wight, Brownsea Island, Anglesey, Cumbria, Kielder Forest, and Formby. Conservation efforts aim to prevent their extinction in the UK. These squirrels are a frequent symbol in English heraldry, typically depicted upright and often shown cracking a nut.

The design is a collaboration between Royal Mint artisans, engravers, and overseen by Gordon Summers, the Royal Mint’s chief engraver, involved support from the Royal Horticultural Society (RHS) and the Royal Society for the Protection of Birds (RSPB).
