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

How rare are my coins? Your latest Scarcity Index Update!

So you think you’ve found a rare coin in your change, but how do you know how scarce it really is? Well, mintage figures only tell part of the story…

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.

50p Scarcity Index

Whilst a fair few coins haven’t moved on our 50p index, the ones that have are making some huge jumps!

50p Scarcity Index

Of course, at the top of the index is a non-mover – the Kew Gardens 50p, closely followed by the Olympic Football 50p which has also defended it’s position in second place.

Interestingly, with the exception of the Kew Gardens and Flopsy Bunny 50ps, the 2011 Olympic 50ps are dominating the top of the list – which could be due to the 2024 Paris Olympics taking place this summer. Some of the biggest Olympic 50p movers are the Boccia 50p which has climbed up 37 places, the Shooting 50p which has shot up 20 places and the Sailing 50p which has floated up 15 places.

There have also been some Olympic 50ps moving down the index, with the Rowing 50p drifting down 15 places, the Gymnastics 50p falling 22 places and the Team GB 50p ending up towards the bottom of the list after dropping 13 places.

The Beatrix Potter 50ps also seem to have had a shakeup, with the Mrs Tiggy-Winkle 50p falling 19 places, the Tom Kitten 50p dropping 14 places and the 2018 Peter Rabbit 50p going up 11 places.

10p Scarcity Index

The 10p index has been well and truly shuffled, with only 1 coin staying put – the X Marks the Spot 10p at the very bottom of the list.

10p Final Q1 – 1

The ones to watch are the V for Villages 10p which has climbed 16 places since our last update and the M for Mackintosh 10p which has moved up 12 places.

To make room for these big jumps, a fair few other designs have had to move down just 2 or 3 places, but most notably is the G for Greenwich Meantime 10p which has fallen 9 places.

The A-Z 10ps seem to be some of the hardest commemorative coins to find 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

Due to the fact that no new commemorative £2 coins have entered circulation since 2016, we generally see less movement on the £2 index, however there are some notable movers since our last update.

Right at the top of the index are 3 of the 2002 Commonwealth Games £2 coins, with the Northern Ireland £2 in first place. With a mintage figure of just 458,000 making it the rarest £2 in circulation, it’s not surprising that the Northern Ireland Commonwealth Games £2 always ends up at the top.

Climbing up the ranks are the Shakespeare Comedies £2 which has fallen 11 places, and the Act of Union £2 which has moved down 9 places and the Britannia and Brunel Portrait £2s which have both dropped 8 places.

The Technology £2 – which was the definitive UK £2 design from 1997 to 2015 and has a combined mintage of 416,145,838 – unsurprisingly remains at the bottom of the index as the most common £2 coin.


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. For example, the Kew Gardens 50p coin commands a premium of up to 200 times face value on eBay and is unsurprisingly top of the 50p Index.

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.

It’s time for your latest Scarcity Index update – your chance to discover the UK’s most sought-after circulation 10p, 50p, and £2 coins of the last three months!

Our Scarcity Index uses data from the Change Checker Swap Centre 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.

50p Scarcity Index

The top and bottom of the 50p index has remained fairly stable, with the Kew Gardens 50p remaining in the top spot, but despite this, there have been some big changes in this latest update…

Moving up the ranks are some of the Olympic 50ps, including Shooting, Cycling and Boccia which have all climbed significantly. These big jumps up mean that others have to shuffle down the index, and we can see that a fair few 50ps have moved down just 1 or 2 places.

Also making their way down the index are the 50 Years of Pride 50p, the Sir Arthur Conan Doyle 50p and the Battle of Britain 50p.
Interestingly, we came across all 3 of these coins in our latest 50p coin hunt, watch it here >>

10p Scarcity Index

A-Z 10p Scarcity Index
A-Z 10p Scarcity Index

The A-Z 10ps seem to be some of the hardest commemorative coins to find in circulation, not surprising when you consider a maximum of JUST 304,000 of each A-Z 10p design entered circulation across 2018 and 2019.

It’s thought that a large percentage of these 10ps have been snapped up by collectors, leaving a limited amount still in circulation, but it is still possible to find them!

One to keep your eye on is the NHS 10p which has shot up 20 places to 5th place, and the Houses of Parliament 10p which has climbed 12 places.

A few less fortunate coins are the King Arthur 10p which has fallen 10 places and the Ice Cream 10p which has dropped 8 places. The X Marks the Spot 10p remains at the bottom of the index, but it’s worth remembering that this 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

We usually see less movement on the £2 index due to the fact that less coins have entered circulation in recent years, however this time, there have been some big movers.

The £2 index usually remains fairly stable as we’ve not had a £2 coin enter circulation since 2016, however this time we have seen a fair bit of movement!

Of course, remaining at the top of the Index is the 2002 Commonwealth Games Northern Ireland £2. With a mintage figure of just 458,000, it’s one of the rarest and clearly still one of the most popular £2 coin designs, even 22 years after entering circulation!

The Guinea £2 climbed an impressive 19 places and the Brunel Portrait £2 moved up 9 places.

Some other big movers are the Wireless Transmission £2 and the Florence Nightingale £2 which have both fallen by 10 places and the Steam Locomotive £2 which has dropped 14 places.


How your Scarcity Index works

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

Trying to find a good quality coin from 15 – 20 years ago, even for a higher mintage issue, is much more challenging than a more recent issue, as coins become damaged over time and are ultimately removed from circulation.

What’s more, some designs are more hoarded than others by people who might not normally collect coins – for example the First World War £2 Coin series.

Finally, it can be up to a couple of years before the Royal Mint eventually confirms the actual mintage for an issue.

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

  • How many of each design are listed as “collected” by Change Checkers, indicating the relative ease of finding a particular coin
  • The number of times a design has been requested as a swap 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.
