On 15 February 1971, the United Kingdom made a monumental change to its currency, switching from the ancient system of pounds, shillings and pence to a new, decimal system. The day itself became known as Decimal Day and was a landmark moment for Britain and The Royal Mint, who struck billions of new coins for the changeover.

Far from being an overnight switch, decimalisation took years of careful planning, a new factory and machinery, new production techniques and processes, and a huge information campaign. Five decades later we celebrate the 50th anniversary of Decimal Day with a new 50p coin, featuring a reverse design created by Dominque Evans, a graphic designer at The Royal Mint, and Jody Clark’s definitive portrait of Her Majesty The Queen on the obverse.

Inspired by the currency that was replaced in 1971, the reverse design conveys the transition from pre-decimal to decimal coins. The coin is available as a gold Proof Piedfort, silver Proof Piedfort, gold Proof, silver Proof and Brilliant Uncirculated edition.
