The NEW Rarest UK 50p splashes onto our Scarcity Index!

Have you just found a coin in your change and are wondering how scarce it is? Well, Change Checker has you covered with our Scarcity Index!

Our Scarcity Index uses data from the Change Checker Swap Centre, combined with a coin’s mintage figure, to determine just how scarce and sought-after your coins are. The information is presented in the easy-to-use indexes below, with arrows to signify how many places up or down a coin has moved since the last Scarcity Index update.

Excitingly, this time we have not one, but TWO new additions to the 50p index as we’ve had the official mintage figures for the coins that entered circulation in 2023!


50p Scarcity Index

Get ready for the 50p Scarcity Index to get a shake up, as we see two new coins enter the rankings!

50p Scarcity Index

Now, you might be thinking – don’t we have a new rarest UK 50p with the 2023 Salmon 50p? Shouldn’t it knock the 2009 Kew Gardens 50p off the top spot?

Well, despite entering circulation just over a year ago, we only recently found out that the mintage figure for the 2023 Salmon 50p was lower than the Kew Gardens 50p, with just 200,000 in circulation! This news means that only a few people will have been lucky enough to find a Salmon 50p in their change, and those who have one aren’t going to be willing to part with it any time soon!

As it’s such a new addition to the Scarcity Index, the Salmon 50p currently ranks 5th from last place, but watch this space – as I’m sure it’ll make its way up the ranks in months to come!

The 2023 Salmon 50p is now the rarest UK 50p in circulation!

Another new coin on the Index is the Coronation 50p, which entered circulation in August 2023, and we now know it has a circulating mintage of 5 million. Whilst this doesn’t make it particularly rare, it’s entered the Index at a respectable position, and we expect it to climb as more people find one in their change.

Other notable movers on the 50p Index are the Gymnastics 50p which has climbed 20 places, the 2018 Peter Rabbit 50p which has shot up 23 places and the Representation of the People 50p and the Tom Kitten 50p which have both gone up by 16 places.

Otherwise, keep reading to find out which 10ps and £2 coins you should be looking out for.


10p Scarcity Index

We’ve seen quite a bit of movement in the 10p index, with all but 3 coins moving positions.

10p Scarcity Index

The big movers are G for Greenwich Meantime 10p which has climbed 16 places, the A for Angel of the North 10p which has gone up 13 places and the V for Villages 10p which has fallen 16 places. The X for X Marks the Spot 10p remains in last place at the bottom of the index.

Collectors will agree that the A-Z 10ps are some of the hardest commemorative coins to come across in circulation – that’s not surprising when you consider a maximum of JUST 304,000 of each A-Z 10p design entered circulation across 2018 and 2019 and it’s thought that a large percentage of these 10ps have been snapped up by collectors.

*Note
It’s worth remembering that our Scarcity Index only ranks the 10ps against each other, so even the ones at the bottom of the list are still incredibly sought-after.


£2 Scarcity Index

The recent mintage figure announcement also confirmed that no new £2 coins entered circulation in 2023, meaning we haven’t had a new commemorative £2 enter circulation since 2016! Due to this, we generally see less movement on the £2 index, however there are a few coins which have made surprising moves.

As usual, the 2002 Northern Ireland Commonwealth Games £2 remains at the top of the index as the most sought after £2 in circulation. It has a mintage figure of just 458,000, making it extremely difficult for collectors to come across in their change.

A few other coins have stayed put, including the King James Bible £2, Robert Burns £2 and the Technology £2 which remains right at the bottom of the index. The most notable movements are the Shakespeare Comedies £2 climbing 15 places and the Trinity House £2 falling by 8 places.

A lot of the other coins have shuffled around by just 1 or 2 places, so it’s worth keeping an eye on our Scarcity Index to see exactly where your coins rank.


How your Scarcity Index works

In the past, collectors have relied on mintage figures alone to identify the scarcest coins.  But they only tell part of the story.  

That’s why we’ve combined the mintage information with two other key pieces of information:

  • How many of each design are listed as “collected” by Change Checkers on our Web App, indicating the relative ease of finding a particular coin
  • The number of times a design has been requested as a swap on our Swap Centre over the previous 3 months, showing the current level of collector demand.

Importantly, as new coins are released and popularity rises and falls across different designs, the Scarcity Index will be updated quarterly. This allows Change Checkers to track the relative performance of the UK’s circulation coins.


How much are my coins worth?

The Scarcity Index doesn’t necessarily equate to value, but it is certainly a good indicator. You can use our 6 point guide to help you determine a more realistic value for your coins.


What about £1 Coins?

The £1 Scarcity Index has already been published for the Round £1 coins. Because they are no longer being issued, this is now set in stone.

Could this Bee a new error £1 coin?

2.975 million King Charles III Bee £1 coins entered circulation in August 2024. Since then, the race has been on to track down these new coins creating a buzz in the collecting world!

Many collectors have already been lucky enough to come across the Bee £1, but perhaps none so lucky as Diane Bath, who spotted a rare error on one of the coins…

The error coin causing a buzz

Diane runs The Post Office in Broughton-in-Furness, Cumbria, where she found a King Charles III Bee £1 struck in entirely one colour!

The image below shows the single metal coin, without the silver-coloured inner piece seen on standard United Kingdom £1 coins:

King Charles III Bee £1 single metal error, found by Diane Bath

£1 coins are struck from a nickel-brass outer ring and an inner piece made from a nickel-plated brass alloy. It’s possible that this error coin was created due to the inner section not being punched out of the nickel-brass before the coin was struck. For confirmation of this, we’d suggest sending the error coin to The Royal Mint for verification.

Diane, a postmistress of over 20 years, told the press: “I am absolutely over the moon. Obviously we handle cash all the time and it’s the most exciting find I’ve ever had in over two decades.”

Worth a pretty penny

The coin was auctioned on 18th October by Ryedale Auctioneers, and whilst it had an estimated value of £500-£800, it actually sold for £1,250!

A similar error occurred when the first 12-sided £1 coins were released back in 2017, although only a small handful of these error coins were ever found. Reportedly, one such error coin sold for over £2,000 at auction!

Ultimately, the selling price of a rare error item like this at auction depends on how much a collector is willing to pay to get their hands on it. So remember, if you’re looking to secure an error coin on the secondary market, always do your research and be aware of fakes before you buy.

Is your 20p coin worth hundreds?

You might want to double check the 20p coins in your change, as one of them just might be worth 6,800 times its face value! A rare 25p coin which made its way into one man’s change in Wiltshire several years ago was put up for auction on 25th September 2024, and sold for a whopping £1,700!

What is a 25p coin?

It’s thought that the 25p coin was made as a trial coin by The Royal Mint before the 20p denomination was official released into circulation in 1982. It’s not known exactly how many of these coins were produced, however experts say that there is likely no more than 50 in circulation. This makes it even rarer than the undated 20p, considered by many as the ‘holy grail’ of change collecting.

The undated 20p has no date on either the obverse or reverse

In terms of shape, the 25p coin looks almost identical to a normal 20p coin, but look a little closer and you’ll see it features a different design. A shield can be seen on one side with the inscription ‘EXPERIMENTAL COIN’ and the year 1981, and the Sovereign’s Orb on the other with the inscription ‘ROYAL MINT TRIAL’.

Trial pieces like these that are sometimes known as ‘pattern coins’, are extremely rare and the chances of one making its way into circulation is even rarer. This makes them incredibly sought after by collectors, especially as this one can be so easily mistaken for an ordinary 20p coin.

Worth a small fortune

This particular 25p coin was listed as part of a specialist sale of historic and modern currency organised by RWB Auctions.

Due to its rarity, experts estimated that the 25p coin would fetch between £500 and £700 at auction, however it actually ended up selling for £1,700 – that’s 6,800 times its face value!

The auction house has previously sold rare coins for huge sums of money, including a scarce Lord Kitchener £2 for £1,000 and a rare 2009 Olympic Athletics 50p for £1,500.

Just 100,000 special edition Blue Peter coin packs were released with the 2009 dated Olympic Athletics coin – making it the only Olympic 50p without a 2011 date
