Why did The Royal Mint revert to the Queen’s decimal first effigy?

2021 marks 50 years since our UK coins turned decimal, in the biggest numismatic change seen in centuries.

In celebration of this significant anniversary, The Royal Mint issued not one, but TWO Decimal Day 50ps in 2021. The reverse designs are the same, but that certainly can’t be said for their obverses…

The first version of the Decimal Day 50p, available exclusively in the 2021 Annual Coin Set, features the original Arnold Machin portrait of Her Majesty The Queen on the obverse – the same obverse used for the UK’s very first decimal coins.

However, the individual coin which was released later in January, featured Jody Clark’s fifth portrait of The Queen instead.

So why did The Royal Mint revert back to the Queen’s first decimal effigy for this new issue? Join Change Checker as we take a closer look…

Spot the Difference

The 50p available in the Annual Set which features the original Machin portrait on the obverse, quickly caught the eyes of collectors as this was the first time we have seen The Royal Mint revert a previous portrait of HM Queen Elizabeth II on a base metal UK coin.

Marking 50 years since our UK coins went decimal, it seemed only fitting that this coin should include Machin’s obverse design.

But, when the Decimal Day 50p was individually released later in January, collectors had the opportunity to get their hands on a second version of this coin, as Jody Clark’s portrait of The Queen featured on the obverse.

So with two versions of the 2021 UK Decimal Day 50p out there, this coin is set to become a real talking point among collectors!

Arnold Machin Portrait

The significance of this anniversary and the fact that the Machin portrait of HM QEII was the first to be used on the UK’s 50p, makes for the perfect excuse to revert back to this previous effigy on the exclusive Decimal Day 50p within the Annual Set.

The UK’s very first decimal coins (5p, 10p, followed by 50p) actually entered circulation before 1971 and as they were circulating together with pre-decimal currency, a new portrait of The Queen was commissioned to help the new coins stand out.

Arnold Machin’s new portrait showed The Queen wearing a tiara given to The Queen by her grandmother, Queen Mary.

We love the fact that collectors have the chance to see this previous portrait reused on this brand new 50p and it certainly makes for interesting collecting!

But that’s not all, as this is not the first time we’ve seen different obverses used on the same coin…

2015 Battle of Britain 50p

In 2015, The Battle of Britain 50p shot to fame as collectors were quick to spot that there were THREE different versions of the coin, with different obverses on each of them.

The Brilliant Uncirculated 50p was issued early in 2015 and was quickly dubbed an ‘error’ coin. The coins, which were sold in presentation packs, had been struck without the denomination in either numbers or writing anywhere on the coin. Chancers were quick to play to this, with some managing to sell on the coins for near to £100 each on the secondary market.

After the controversy surrounding the coin erupted, the Royal Mint confirmed that the 50p intended for circulation later on in the year would have the ’50 PENCE’ denomination. But was this after they had realised their mistake?

So how did this coin end up with three different obverses?

Each version of this coin has caused a stir in the collecting world. Not only does this Battle of Britain 50p fail to feature a denomination on the Brilliant Uncirculated version, but the obverse is different for each finish used for the coin – a first for a UK commemorative coin.

In 2019, a brand new re-issued Brilliant Uncirculated version of the Battle of Britain 50p (from the 2019 50th Anniversary of the 50p Military Set) saw Jody Clark’s portrait and the 50 PENCE denomination – making this the FOURTH version of this 50p!

How much is my coin worth? January 2021 eBay Tracker Update!

Good news Change Checkers – your latest eBay Tracker and Valuation Index is here!

Whilst the secondary market can be a bit of a minefield, we’ve put together an easy way for you to see how much the Top 10 UK coins and banknotes are selling for right now.

eBay Tracker

Find out which coins and notes have been the key movers and shakers in the updated eBay Tracker below.

We’ve seen a huge jump in price for the Undated 20p, increasing by a huge £9! This coin dropped in value in the last eBay Tracker so it’s interesting to see it climb to £50 this month.

This coin is regarded by many as the Holy Grail of change collecting, and back in 2008, the undated 20p saga encouraged an entire country to start carefully checking their coins.

Undated 20p

This mule coin came about when the new Royal Shield 20p coins were struck for circulation, with no date on the reverse. The old die was accidentally used, meaning a batch was issued with no date on either side of the coin.

The undated 20p became the first coin in over 300 years to enter circulation without a date and it’s estimated by The Royal Mint that no more than 250,000 coins made it into circulation.

So, there’s no surprises people are prepared to pay a pretty penny on the secondary market to secure one for their collection!

2018 Sir Isaac Newton 50p

There’s also been an increase in the sold prices of the 2018 Sir Isaac Newton 50p, jumping up by £6.00.

As the 2018 Sir Isaac Newton 50p is a strike your own version, this indicates that collectors are likely heading to secondary markets to get hold of these types of coins, as The Royal Mint Experience remains closed.

With less cash also being used in the past few months because of the current climate, it’s clear this has influenced collector behaviour on the secondary markets too, as people are unable to exchange coins in the same ways they were previously. This therefore drives the price up, as demand for the coin increases.

Additionally, with more time being spent at home and people seeking new hobbies to keep themselves entertained, new collectors are perhaps becoming more aware of rare and collectable coins that might be worth owning and as a result, are heading to the secondary market to get hold of one.

But will we continue to see the price of this coin rise on the secondary market as we head back to a new kind of ‘normal’? Only time will tell and we’ll have to wait for the next eBay Tracker update to find out!

As collectors are unable to source coins in the usual ways due to the current climate, it’s interesting that we’ve seen some big changes this month, as people head to secondary markets to secure coins for their collection.

Valuation Index

Overall, there’s been a 1.3 point increase value for the Top 10 UK coins and banknotes since June’s update and this is no doubt due to the increase in price for 7 of the coins in the tracker.

After an impressive spike in our last update, we’ve seen another increase in January – taking it to the highest we’ve seen since the Tracker started!

My coin isn’t on the eBay Tracker

The eBay Tracker follows the movements of the Top 10 UK coins and banknotes, however if your coin doesn’t appear on the tracker you can use our 6 point guide to help determine realistic a value for your coin.

So now that you’re up to date with our latest eBay Tracker, will you be selling any of the coins in your collection or will you continue to save them? Let us know in the comments below.

How does the eBay Tracker work?

The Change Checker eBay Tracker takes the last 9 sold prices achieved on eBay and gives the median price achieved (rounded to the nearest 50p). By taking the median, rather than an average, we avoid skewing created by one or two excessive prices achieved.

Please note that the Change Checker eBay Tracker is only ever designed to be a guide as to prices achieved on eBay. Prices may vary depending on collector demand and the quality of the coin being sold. It does not provide any guarantee as to future values of coins.


If you’re interested in coin collecting, our Change Checker web app is completely free to use and allows users to:

January 2019 eBay Tracker Update

The 50th Anniversary of Decimal Day 50p

On February 15th 1971, the UK’s currency went decimal and this enormous change to UK coinage called for one of the biggest publicity campaigns our nation had ever seen!

To celebrate the 50th anniversary of ‘Decimal Day’, The Royal Mint released a UK 50p.

This Decimal Day 50p, designed by Dominique Evans, features overlapping pre-decimal coins in an ode to Decimal Day, with the date ‘1971’ at the centre of the design.

2021 Decimal Day 50p

Over the years, the 50p has become the most-collected and best-loved decimal coin in the UK. We’ve seen some amazing coins issued since Decimalisation. In this blog, we take a closer look at some of Change Checker’s favourites.

2019 50th Anniversary of the 50p Coin

2019 marked a milestone moment for coin collectors as the world’s first seven-sided coin celebrated its 50th anniversary. To celebrate the anniversary, The Royal Mint issued this 50p.

2019 50th Anniversary of the 50p Anniversary Coin

This coin was designed by The Royal Mint design team and is said to ‘pay tribute to the science that gave us the world’s first seven-sided coin’.

Featuring Christopher Ironside’s iconic Britannia on the reverse, inscribed with ‘NEW PENCE’ just as the original 1969 coin was, this unique 50p has not one, but two special features:

  1. An exclusive never-before-seen mint mark; the Spirograph type design has been drawn from an extension of lines forming the 50p shape
  2. minting first; on the outer rim of the reverse design, the letters A-G appear on each point and are joined by crossing lines.

The first-ever £2 coin!

In 1986, a brand new UK denomination was introduced in the form of a £2 coin.

1986 Commonwealth Games £2

Prior to the introduction of the bi-metallic £2 coins in 1998, single-coloured, nickel-brass £2 coins were issued, purely to mark special occasions. Between 1986 and 1996, there were seven different designs of the single-coloured £2 coins.

The 1986 Commonwealth Games £2 coin changed the face of UK commemorative coins, being the first of its denomination to be struck and the first British coin being issued to commemorate a sporting event.

Do you remember the old specification £2 coins? Let us know in the comments below!

The bi-metallic £2 coin!

The new type of £2 coin was introduced in 1997 and featured an innovative bi-metallic design – the first in the history of British coinage.

Technology £2 – Issued 1997 – date.

The concentric circles on this design by Bruce Rushin represent mankind’s technological evolution from the Iron Age at the centre, to the cogs and wheels in the first ring representing the Industrial Revolution.

The next ring symbolises the computer age with a pattern derived from a silicon chip and the final outer ring represents the age of the Internet with a connecting web of lines.

This design was used on definitive £2 coins from 1997 to 2015!

Britain’s Round Pounds

The first UK £1 coin was issued in 1983 to replace the £1 banknote, which only lasted a few months in circulation! The £1 coin quickly became a hit with collectors, with everyone trying to hunt down the different designs.

1983 Royal Coat of Arms £1

The first £1 coin design features the Royal Coat of Arms designed by Eric Sewell, a chief engraver at the Royal Mint. It also features the edge Inscription: DECUS ET TUTAMEN.

This coin was issued in 1983, 1993, 2003, 2008 and has a circulating mintage of 623,304,510.

After more than 30 years in the nation’s pockets, the familiar round £1 coin was replaced with an all new, 12-sided £1 coin in 2017 and it lost its legal tender status at midnight on 15 October 2017.

Despite this, some round pounds remain incredibly popular with collectors, due to their designs and their low mintages.

Nations of the Crown £1

The new £1 coin first entered circulation in March 2017 and it features 12 sides.

2016 Nations of the Crown £1

Billed as the most secure circulating coin in the world, the new £1 has been formally named ‘The Nations of the Crown 2017 UK £1′.

The coin, designed by 15-year-old David Pearce following a public competition in 2015, is made up of the English rose, the Welsh leek, the Scottish thistle and the Northern Irish shamrock emerging from one stem within a royal coronet to represent the four constituent countries of the United Kingdom.

5p and 10p Coins

In 1968 the 10 New Pence coin entered circulation to replace the florin as part of Britain’s conversion to a system of decimal currency.

10 New Pence

The public was uncertain about using this new coin to start with, after generations of pounds, shillings and pence, meaning the Decimal Currency Board still needed to reassure suspicious Britons to go decimal.

Our 10p coin has seen three different definitive designs and in 2018 we saw our first-ever commemorative designs, with the release of 26 A-Z of Great Britain 10p coins!

A-Z of Great Britain 10p coins – first issued in 2018.

In April 1968, 5p coins were issued as a replacement for shillings in preparation for decimalisation in 1971.

5 New Pence.

These were released into circulation at the same time as the very first 10p coins.

In 1990 and 1992, the specifications of the 5p and 10p were reduced, respectively. On 27th June 1990 the new 18.00mm 5p was introduced and 30th September 1992, a reduced size version of the 10 pence coin was introduced


Since decimalisation, we’ve seen some incredible definitive and commemorative designs to our UK coins.
