How much are your RARE coins and banknotes worth? Your August 2025 eBay Tracker update!
Do you have a rare coin or banknote in your collection and often wonder ‘how much could it be worth?’ Whilst there’s no definitive answer when valuing coins, you can take a look on the secondary market to get a ballpark figure.
In our latest eBay Tracker Update, we’ve done the hard work for you to work out how much the top 10 UK coins and banknotes are selling for right now…
In June 2024, we made some changes to the coins and banknotes we track, to make sure we’re looking at the most sought-after ones right now. You might notice that your favourite coin or banknote that we’ve tracked in the past is missing, but you can always check out our previous eBay Tracker updates to see how their value has changed over time.
eBay Tracker
** UPDATE 22/09/25 **
It’s now been announced that a further 8.84 million 2025 Bee £1 coins are being released into circulation, meaning it’ll actually have a circulating mintage of 9,010,000. This eBay Tracker was published before the announcement and therefore refers to the 2025 Bee £1 as the rarest £1 in circulation.
2025 Bee £1
Following the announcement in August 2025 that the 2025 dated Bee £1 coin had an initial circulating mintage of just 170,000 – we temporarily added it to our eBay Tracker. Since then, it’s been announced that 8.84 million more 2025 Bee £1 coins have entered circulation, giving more collectors the chance to find one!
The median selling price for 2025 Bee £1 coins sold after the announcement on 20th August 2025 was £12.90, a 30% increase from those sold before the news.
Do you have a 2025 Bee £1 in your collection? Maybe you’re one of the lucky ones to have found it in circulation, or perhaps you have the 2025 Definitive Set which includes the 21025 Bee £1 in Brilliant Uncirculated quality – let us know in the comments!
2023 Salmon 50p
It’s been almost a year since we heard that we have a new rarest UK 50p in circulation – the 2023 Salmon 50p! In October 2024, it was announced that the 2023 Salmon 50p had a mintage of just 200,000, 10,000 less than the previous rarest 50p – the 2009 Kew Gardens 50p.
Despite the 2023 Salmon 50p now being the rarest UK 50p in circulation, it appears that some of the excitement around it has faded since our last eBay Tracker update, as the median selling price has fallen by 23%.
Kew Gardens 50p
Now the second rarest UK 50p in circulation, a 2009 Kew Gardens 50p can set you back around £120 on the secondary market, which is a 16% decrease since our last update – but still a great return on a 50p coin!
Undated 20p
When it comes to coins that many collectors dream to find in their change, the Undated 20p is right at the top of the list. With no official mintage figure and the mystery of just how many slipped into circulation, this little error coin has become legendary!
In this eBay Tracker, the median selling price sits at £44, which is actually £19.95 lower than our last update. So, if you’ve been holding out to secure one for your collection, now might be the perfect time to swoop in and secure one before prices creep back up.
2002 N Ireland Commonwealth Games £2
Just like the Kew Gardens 50p, the rarest £2 coin in circulation – the 2002 Commonwealth Games Northern Ireland £2 – is one of the hardest coins to find in the wild, but often gets overlooked. With a circulating mintage of just 485,500, it’s one of the rarest coins out there, but having been in circulation for over 23 years, a large percentage of them have most likely been snapped up by collectors already.
Those that are willing to part with theirs are asking for around £34 on the secondary market, which is a £2.41 increase since our last update.
Valuation Index
Using the total price of the coins and banknotes tracked, the Valuation Index follows the rise and fall of their overall value, measured in points against the baseline set in January 2017.
Since the last update in December 2024, there’s been a 13% overall decrease in the value of the Top 11 coins and banknotes on the eBay Tracker. With secondary market prices falling, now might be the time to pick up one of these coveted coins or banknotes for your collection!
eBay Tracker FAQs
How does the eBay Tracker work?
The Change Checker eBay Tracker takes the last 9 sold prices on eBay and gives the median price achieved. By taking the median, rather than an average, we avoid skewing figures with excessively high or low prices.
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.
My coin isn’t on the eBay Tracker
The eBay Tracker follows the movements of the top UK coins and banknotes, however if your coin doesn’t appear on the tracker you can use our 6 point guide to help determine the realistic value for your coin.

Red Arrows 50p Swap Madness at RIAT!
Our most recent 50p swap at the Royal International Air Tattoo caused queueing chaos, as thousands of excited aviation fans flocked to the Change Checker stand to swap their 50ps for the 2025 Red Arrows 50p.

How sought-after are your coins? Your Scarcity Index Update
It’s time for your latest Scarcity Index update, where we reveal the UK’s most sought-after circulation coins!
This information has been compiled using data from the Change Checker Swap Centre and 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.
50p Scarcity Index
Since our last update, most of the 50ps have had a shuffle around, although the bottom of the list has remained fairly stable.
The 2009 Kew Gardens 50p held the title for the rarest UK 50p in circulation for 15 years with a mintage of just 210,000, before it was replaced by the 2023 Salmon 50p, which has a mintage figure 10,000 less. Given the amount of time the Kew Gardens 50p spent establishing itself as the holy grail of coin collecting, it remains at the top of our Scarcity Index as the most sought after 50p.
It’s been nearly a year since the mintage figures for the 2023 Salmon 50p were announced, and we found out that just 200,000 are in circulation! Despite a slow start on the Scarcity Index, it is now climbing up the ranks, having shot up 13 places since our last update.
Some of the 50ps that have moved up the index significantly include the Libraries 50p which climbed 25 places, the Olympic Rowing 50p which went up 16 places and the Olympic Hockey 50p, climbing 21 places.
Moving down the index is the Ironside 50p which has fallen a whopping 24 places, and the Paddington at the Palace and Tom Kitten 50ps which have both gone down 15 places.

Otherwise, keep reading to find out which 10ps and £2 coins you should be looking out for.
£2 Scarcity Index
Although no new commemorative £2 coins have entered circulation since 2016, there has been quite a shakeup in the £2 Scarcity Index this time.
As always, the 2002 Northern Ireland Commonwealth Games £2 remains in 1st place and the 2002 England Commonwealth Games £2 in 2nd place due to their extremely low mintage. Our previous definitive £2 coin design – the Technology £2 – remains in last place, which isn’t surprising considering it’s whopping mintage of 416,145,838 across all issuing years!
Both the Mary Rose £2 and the Rugby World Cup £2 have fallen 10 places, however the Kitchener First World War £2 has shot up 11 places.
Other notable changes are the Brunel Portrait £2 which has dropped 9 places, the Trinity House £2 which climbed 6 places and the Shakespeare Histories £2 which shot up 6 places.
The Final 10p Scarcity Index
As no new commemorative 10p coins have entered circulation since the A-Z of Great Britain 10ps issued in 2018 and 2019, we’re now at a point where we can set the 10p Scarcity Index in stone. The fluctuations we’ve seen in recent Scarcity Index updates are likely caused by a spike in the amount of swaps being listed on the Change Checker Swap Centre. See our final 10p Scarcity Index below.
This is also the case for the Round £1 coins which are no longer being issued, you can find the final £1 Scarcity Index here: Round £1 coins.
How our 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.
