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!

Rarest A-Z 10p coins revealed! 2019 Mintage Figures Update
Exciting news! The Royal Mint have revealed the latest mintage figures for 2019 coins!
Three 50p coins entered circulation in 2019 and collectors across the nation have been debating how rare each one might be.
What’s more, we were all eagerly awaiting the reveal of the mintage figures for the 2019 A-Z 10p coins.
But now the official figures have been revealed and it looks like there are some particularly rare ones we should be looking out for…
The Rarest A-Z 10p Coins!

Whilst each of the 2018 dated A-Z 10p coins had the same mintage of 220,000, this year the mintages are varied among the designs!
Collectors who have managed to find the 2019 dated Q, W, Y, Z, and R 10p coins will be delighted to see that these have a lower mintage than the other 21 designs from that year.

The 2019 World Wide Web, Yeoman Warders and Zebra Crossing 10p coins all have a mintage of JUST 63,000! When you compare that to the rarest 50p in circulation, the Kew Gardens 50p, which has a circulating mintage of 210,000, it puts into perspective just how rare these 10p coins are.
When you combine the 2018 and 2019 mintages for these coins, it confirms that a total of 283,000 of each design has entered circulation.
The other 10p coins to look out for are the Robin and Queuing 10p, with a 2019 mintage of 64,000 and 83,000 respectively.

50p Mintage Update

Sherlock and Paddington Join the Chart!
The Paddington Bear coins are some of the most popular 50ps in recent years and collectors have been waiting to find out just how rare they are.
It’s now been confirmed that 9,001,000 of each 2019 design (Paddington at the Tower and Paddington at St. Paul’s Cathedral) were issued into circulation.


Whilst these coins aren’t exactly rare, they are certainly a collector favourite, with children, parents, and 50p collectors alike all wanting to find all four coins from the series in their change. Have you got these coins in your collection? Let us know in the comments below!
The mintage figure for the 2019 Sherlock Holmes 50p has also been confirmed. 8,602,000 of these 50p coins, celebrating the 160th anniversary of the birth of author Sir Arthur Conan Doyle, were struck for circulation.
What about the Olympic 50ps?
In 2012, the release of the Olympic 50p series kick started a collecting frenzy across the nation.
It’s estimated that around 75% of these coins have been removed from circulation by collectors which means they are incredibly sought-after, especially considering these 50ps have some of the lowest mintage figures in circulation…
Many of the Olympic 50ps have a mintage less than 2,000,000 with the rarest (the Olympic Football 50p) having a mintage of just 1,125,500.

Taking these rare 50ps into consideration, the 2018 Peter Rabbit and Flopsy Bunny coins would sit in joint sixth position, below the Kew Gardens, Football, Wrestling, Judo and Triathlon 50ps.
£2 Coin Update
As well as updating the 50p mintage figures, The Royal Mint also revealed that no £2 coins were issued into circulation in 2019.
There have been no new £2 coins issued into circulation since 2016, which may in part be due to the introduction of the new 12-sided £1 coin in 2017.

It was recently confirmed that The Royal Mint has no plans to strike any £2 coins for circulation for the next 10 years, so unfortunately, there may not be any mintage updates for this denomination for a while.
No 1p or 2p coins entered circulation in 2018 either, perhaps suggesting it’s time we question what the future has in store for our beloved coppers.
Have you been lucky enough to find any of these coins in your change? It’s always exciting when new mintage figures are revealed and your realise just how rare the change in your pocket really is!
We’ll be updating the Change Checker Scarcity Index this month and it will be exciting to see how these new figures impact the index.
