Overview

• Royal Mint has confirmed that the 2023 Atlantic Salmon 50p, with a mintage of just 200,000, is the rarest 50p coin in circulation.
• The coin was issued in November 2023 as one of eight definitive designs featuring UK flora and fauna following King Charles III’s accession.
• Variants without the privy mark—a small crown at the nape of the king’s portrait—are the most valuable examples.
• Current valuations by the Britannia Coin Company start at £150, with some eBay listings reaching £260.
• Collectors are urged to inspect coin condition, verify privy mark absence, and obtain professional grading to maximise value.
