The eBay Tracker gets a shake up! June 2024 update

If you have any of the below coins or banknotes in your collection, read on to find out how much they could be worth in our latest eBay Tracker and Valuation Index update!

Since January 2017, our eBay Tracker has monitored the secondary market prices of 10 of the top UK coins and banknotes. However, due to demand for rare and sought after coins changing over the years, and the introduction of the new King Charles III banknotes, we’ve updated the coins and banknotes on our tracker to give you the most relevant data on the top UK coins and banknotes right now.

You might notice that your favourite coin or banknote that we usually track is missing, but you can always check out our previous eBay Tracker updates to see how their value has changed over time. 


eBay Tracker

Of course, we’ll still be tracking the secondary market selling price of the rarest 50p and £2 in circulation – the 2009 Kew Gardens 50p and the 2002 Northern Ireland Commonwealth Games £2, as their extremely low mintage figures make them some of the hardest coins to find in your change.

We’ll also keep monitoring the undated 20p, the 92/93 EEC 50p, the 2018 Sir Isaac Newton 50p and the rarest Olympic coin – the Football 50p.

Kew Gardens 50p

In 2014, 5 years after its release, The Royal Mint revealed that only 210,000 Kew Gardens 50p coins had been struck for circulation, making it the scarcest UK coin in circulation. And 10 years later, people are still willing to pay hefty sums to get their hands on one, in fact it’s the only coin on our tracker to have increased in price in the last 6 months.

The average secondary market value for a Kew Gardens 50p is currently around £145, which is just £7 more than our last update.

Undated 20p

The undated 20p is often thought of as the ‘holy grail of change collecting’, as it’s not been confirmed just how many of these error coins made it into circulation. As one of the most sought-after coins, it’s at the top of many collectors’ wish lists, and some are willing to pay up to £50 to get their hands on one!

Although that’s 22% decrease since our last eBay Tracker update, it’s still a whopping 250 times the coin’s face value!

Her Majesty Queen Elizabeth II 50p

The very first UK coin to feature King Charles III on the obverse after the passing of Queen Elizabeth II in September 2022 paid tribute to Her Majesty’s life and record breaking reign. As only the second ever royal UK 50p AND the first UK coin to feature the new monarch, collectors were keen to get their hands on the 2022 Her Majesty Queen Elizabeth II 50p.

Those who weren’t able to find one in their change straight away took to the secondary market and, back in January 2023 when it first appeared on our eBay Tracker, were willing to pay up to five times its face value! Since then, however, the median secondary market selling price has slowly decreased, as more and more are being found ‘in the wild’ and since The Royal Mint announced that there are 9.6 million of them in circulation – more than the amount of definitive Royal Shield 50ps that entered circulation the same year.


New additions to the eBay Tracker

As of June 2024, we’ll start tracking the median secondary market selling price of some other rare coins in circulation as well as some newer coins and banknotes that are proving hard for collectors to find.

Salmon 50p

The first coin to enter circulation from the New UK Coinage set featuring King Charles III was the Atlantic Salmon 50p. In November 2023, an estimated 500,000 Salmon 50ps entered circulation, but The Royal Mint are yet to announce the definitive mintage figure.

Collectors haven’t been having much luck finding them in their change and due to this, they’ve been selling for a pretty penny on the secondary market, fetching up to £14.50!

Have you found an Atlantic Salmon 50p in your change? Let us know where you found one!

W (World Wide Web) 10p

The A-Z of Great Britain 10p series was first issued in 2018, with a 10p representing something quintessentially British for each letter of the alphabet. A second wave of these 10ps was issued in 2019, and out of all of them, the 2019 W for World Wide Web 10p has the lowest mintage figure of just 63,000 – even lower than the Kew Gardens 50p!

According to our eBay Tracker, you can expect to pay up to £4.50 for a W 10p on the secondary market, not a bad return on a 10p coin!

The first ever King Charles III Banknotes

The first ever King Charles III banknotes entered circulation on 5th June 2024, however they were only available at a select few locations. As these new notes will only be issued to replace worn or damaged Queen Elizabeth II going forward, they’ve inevitably become extremely sought after by collectors.

A King Charles III £5 banknote will cost you up to £25 on the secondary market, whilst a £10 note featuring His Majesty will set you back £21.

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 at January 2017.

Change Checker Valuation Index

Since the last update in January 2024, there’s been a 5% decrease in the overall value of the Top 12 coins and banknotes on the eBay Tracker, but bear in mind that the coins and banknotes tracked have been updated, as represented by the vertical dotted line on the graph.


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.

A closer look at the first ever King Charles III Banknotes

First King Charles III Banknotes ENTER CIRCULATION!

The first banknotes featuring King Charles III entered circulation on 5th June 2024, here’s everything you need to know.

Hot off the press

In November 2023, The Bank of England started printing new banknotes featuring King Charles III at a rate of 6 million in 24 hours. The delay in them entering circulation was apparently caused by machines such as self service tills not being able to recognise the new image and needing to be recalibrated.

The Bank of England’s chief cashier, Sarah John, said “There is a lot to do to ensure that machines used up and down the country can accept the banknotes. They all need to be adapted to recognise the new design, with software updates, and that takes months and months. Otherwise, we will be putting a banknote out there that people simply would not be able to use.”


A sustainable transition

Taking guidance from the Royal Household, the new banknotes will only be issued to replace worn or damaged Queen Elizabeth II notes, meaning both monarchs’ portraits will co-circulate for the foreseeable future.

There are approximately 4.7 billion Queen Elizabeth II banknotes currently in circulation, worth an estimated £82 billion, so don’t worry – they’ll still be accepted in shops as well as the new King Charles III notes.

This transition phase will minimise the environmental and financial impact of the change, in keeping with the King’s vision for a more sustainable future.

King Charles III’s portrait will now appear on the front of the notes, an image based on an engraving of a picture of His Majesty taken in 2013, however there will be no changes to the current reverse designs:

  • Winston Churchill (£5)
  • Jane Austen (£10)
  • JMW Turner (£20)
  • Alan Turing (£50)

Security Features

All denominations of the new banknotes share some of the same security features which you can use to verify the authenticity of the note.

A portrait of King Charles III is printed on the window with the denomination and ‘Bank of England’ printed twice around the edge.

When tilting the note from side to side, the word within the hologram should change between the value of the note, ‘Five’, ‘Ten’, ‘Twenty’ or ‘Fifty’ and ‘Pounds’.

Silver foil patch
A silver foil patch contains a 3D image of the coronation crown.

The printed lines and colours on the note are sharp and clear, with no smudges or blurred edges. If you use a magnifying glass, you should be able to see the value of the note written in small letters and numbers below the monarch’s portrait.

Feel of polymer and raised print
The note is printed on polymer, a thin and flexible plastic. On the front of the note, you can feel the raised print on the words ‘Bank of England’ and in the bottom right corner.

Ultraviolet number
Under a UV light, the denomination number appears in bright green and red on the front of the note.

On the other side of the silver foil patch showing the coronation crown, the £50 has a red foil patch containing the letters ‘AT’, paying tribute to Alan Turing who features on the note.

Rare serial numbers

Whenever new banknotes are issued, it causes quite a stir in the collecting community, with serious collectors rushing to secure the notes with the lowest serial numbers.

The Bank of England generally hold back some of the notes with the earliest serial numbers, donating them to people or institutions that were involved in the development of the note, but others can fetch hefty sums at auction!

For example, serial numbers such as AK47 due to the machine gun connotations, and 007 which could be desirable to James Bond fans are considered collectable, as well as serial numbers representing key dates relating to the figure on the reverse of the note.

On 11th July 2024, a King Charles III £20 note with the serial number EH 01 000002 sold for £7,000 at auction – that’s 350 times its face value!
