The Royal Mint’s 2023 definitive set introduced eight reverse designs for the UK’s circulating denominations, from 1p to £2. The designs feature wildlife and the floral emblems of the four nations.
On 25 August 2026, the first 10p coins bearing King Charles III’s portrait entered circulation. Their reverse shows a capercaillie.
The 2023 definitive set
The set was the first new UK definitive coin series in 15 years. Each coin has King Charles III’s coinage portrait by Martin Jennings on the obverse. The reverse designs share three interlocking Cs, a motif inspired by Charles II’s cypher. The Royal Mint developed them with support from the Royal Horticultural Society and the Royal Society for the Protection of Birds.
Circulation
The Royal Mint releases new definitive coins as banks and post offices request them. Its 2023 Definitive Sets FAQs explain how the designs enter circulation.
In its 2026 announcement, the Royal Mint said coins bearing Queen Elizabeth II’s portrait remain legal tender and in active circulation.
