Overview

• Royal Mint data show just 200,000 Atlantic Salmon 50p coins were minted in 2023, narrowly undercutting the 210,000-strong 2009 Kew Gardens issue.
• Kew Gardens 50p pieces now routinely fetch over £150, with record eBay sales topping £700 in recent weeks.
• Other limited-run 50p designs, including Olympic event coins and Beatrix Potter editions, trade for up to £75 despite mintages exceeding one million.
• Error coins such as the Lord Kitchener £2 lacking its denomination inscription and the 1983 “new pence” 2p can command more than £1,000 and £2,000 respectively.
• An undated 2008 mule error 20p is valued at about £50, underscoring experts’ advice to examine loose change for hidden treasures.
