DECIMAL WEEK: 50 years since 'D Day'


11 February 2021
All this week at we'll be marking the fiftieth anniversary of Decimal Day (also known as D Day) in the UK with special articles and guides…

Fifty years ago, Decimal Day saw the UK and Ireland switch to a brand new currency, leaving behind the pounds, shilling and pence that many of us still remember. Find out more about decimalisation all this week, in association with NGC UK, the leading third-party grading service for coins, tokens and medals.
