A deep dive into decimalisation…

In 1971, Britain officially went ‘decimal’ after a long period of campaigns in preparation for the move.

The transition to decimalisation was the biggest change to the UK’s monetary system in over 1000 years and understably was met with caution by the public.

Rationale presented by decimal enthusiasts was opposed by those who were cautious of the effects of a new decimal coinage system.

In this blog, we take a close look at this controversial monetary move as we take a deep dive into Decimalisation…

The Decimal Debate

For centuries, Britain’s coinage consisted of pounds, shillings, pence, farthings, crowns, half pennies… the list goes on!

This complex system had first been raised for debate in 1847 by Sir John Bowring, who proposed a call for it to be changed to a currency based on units of ten. As a result of his proposal, the nation’s first decimal coin appeared – the farthing.

It wasn’t until 1961 however, that the Government set up a special committee to think about whether Britain should introduce a decimal currency.

On 1 March 1966 the Chancellor of the Exchequer, James Callaghan, announced that pounds, shillings and pence would be replaced by a decimal currency, with a hundred units in a pound.

Making the Change

The changeover was a huge task and the public and businesses of Britain required all the necessary information to make the changeover as smooth as possible.

The volume of coins required to be produced was far greater than The Royal Mint’s production capabilities at Tower Hill and it brought about their move to Llantrisant, South Wales, in 1968. It was here that the first of almost six billion coins required for decimalisation went into production.

In 1968 the new 5p and 10p coins were introduced. They were the same size and value as the existing one and two shilling coins to make the transition easier for the British public.

It was in 1969 that the first seven sided coin – the 50p – was introduced to replace the 10-shilling note as a more economical alternative and then finally, on Monday 15 February 1971, the transition was complete when the half penny, 1p and 2p coins were also introduced.

Our Dear Decimals

From Britannia to the Royal Shield design, we’ve grown to love our decimal coins but in their 50th anniversary year, it’s wonderful to see the journey they’ve made.

We’ve seen over 100 different designs of our 50p coin since it’s introduction in 1969, over 60 different £2 coin designs since 1986, and a complete re-design of our £1 coin’s specification to a 12-sided coin, from the original round pounds in 1983.

In 2018 we even saw our first-ever commemorative 10p coins, with over 26 designs celebrating quintessentially British icons!


We’ve certainly been blessed with lots of decimal coins to collect and here’s hoping there’s many more to come! There’s not been a new £1 coin design since 2016 so perhaps that will come next…

Happy Birthday Ma’am!

Not only is our Queen now the longest reigning monarch in British history, but today Her Majesty is celebrating her 92nd Birthday – the only British sovereign to reach this milestone.

To celebrate, we’ve put together a timeline of the most significant moments in history while looking through some of the coins that have adorned Her Majesty’s portraits through the years.

Elizabeth immediately became Queen after her father King George VI passed away. Her Coronation was delayed for 16 months because of a traditional period of mourning that follows the death of a Monarch. The first commemorative crown of her reign was designed by Gilbert Ledward and captured the hearts of the nation.

The first coins of Queen Elizabeth II’s reign featured the first portrait of Her Majesty by Mary Gillick. The portrait is remembered for reflecting the optimistic mood of the nation and was also used on coinage in many of the commonwealth countries.

In 1965, a crown was released by the Royal Mint which changed everything. This particular Crown is famous for being the first British coin to feature anyone outside the Royal Family – Sir Winston Churchill.

On Decimal Day, the UK and Ireland decimalised their currencies.  The new currency system meant that the pound would be divided into units of ten, including half, one, two, five and 50 pence.

The marriage of Queen Elizabeth II and Prince Phillip Mountbatten took place on the 20th November 1947 and in 1972, the couple celebrated 25 years together. The Royal Mint issued the first British coin to have a face value of 25p to mark their 25th Wedding Anniversary. 

The thirteenth Commonwealth Games were held in Edinburgh in 1986 which saw the striking of the very first commemorative £2 coin. Not only that, it was the first coin to commemorate a sport.

The very first bi-metallic coin was issued in 1997 – one year prior to the portrait change. This coin is the one and only year that Raphael Maklouf’s portrait appears on the bi-metallic £2 coin. His portrait features Queen Elizabeth II wearing a necklace, which earned the coin its unique status and nickname in the collecting world, the ‘Queen with a Necklace’ £2. 

2011 saw the introduction of a new design for the 1oz Silver Britannia who has a long standing history with British coinage. The coin features the 4th portrait by Ian Rank-Broadley which is regarded as being a realistic and mature representation of the Queen.

In 2015, British History was made as Her Majesty Queen Elizabeth II celebrated an incredible Royal milestone, becoming our longest reigning monarch. This remarkable £20 coin was issued in celebration and features all 5 portraits of Her Majesty. The obverse features the fifth portrait of Her Majesty as 2015 was the first year that the Jody Clark portrait was used on UK coinage.

To celebrate the 90th Birthday of Her Majesty Queen Elizabeth II a selection of brand new commemorative coins were issued. Designed by Christopher Hobbs, the coin depicts nine roses – one for each decade of her life as well as the number ’90’ in the centre.

2016 proved to be a significant year for collectors and the 90th Birthday celebrations were no exception. The coins that appeared throughout Her Majesty’s reign have proved to be very popular over the years and we’re sure the 90th Birthday commemorative coins will be favourites among collectors in years to come.
