Good news Change Checkers – your latest eBay Tracker and Valuation Index is here!

Whilst the secondary market can be a bit of a minefield, we’ve put together an easy way for you to see how much the Top 10 UK coins and banknotes are selling for right now.

eBay Tracker

Find out which coins and notes have been the key movers and shakers in the updated eBay Tracker below.

We’ve seen a huge jump in price for the Undated 20p, increasing by a huge £9! This coin dropped in value in the last eBay Tracker so it’s interesting to see it climb to £50 this month.

This coin is regarded by many as the Holy Grail of change collecting, and back in 2008, the undated 20p saga encouraged an entire country to start carefully checking their coins.

Undated 20p

This mule coin came about when the new Royal Shield 20p coins were struck for circulation, with no date on the reverse. The old die was accidentally used, meaning a batch was issued with no date on either side of the coin.

The undated 20p became the first coin in over 300 years to enter circulation without a date and it’s estimated by The Royal Mint that no more than 250,000 coins made it into circulation.

So, there’s no surprises people are prepared to pay a pretty penny on the secondary market to secure one for their collection!

2018 Sir Isaac Newton 50p

There’s also been an increase in the sold prices of the 2018 Sir Isaac Newton 50p, jumping up by £6.00.

As the 2018 Sir Isaac Newton 50p is a strike your own version, this indicates that collectors are likely heading to secondary markets to get hold of these types of coins, as The Royal Mint Experience remains closed.

With less cash also being used in the past few months because of the current climate, it’s clear this has influenced collector behaviour on the secondary markets too, as people are unable to exchange coins in the same ways they were previously. This therefore drives the price up, as demand for the coin increases.

Additionally, with more time being spent at home and people seeking new hobbies to keep themselves entertained, new collectors are perhaps becoming more aware of rare and collectable coins that might be worth owning and as a result, are heading to the secondary market to get hold of one.

But will we continue to see the price of this coin rise on the secondary market as we head back to a new kind of ‘normal’? Only time will tell and we’ll have to wait for the next eBay Tracker update to find out!

As collectors are unable to source coins in the usual ways due to the current climate, it’s interesting that we’ve seen some big changes this month, as people head to secondary markets to secure coins for their collection.

Valuation Index

Overall, there’s been a 1.3 point increase value for the Top 10 UK coins and banknotes since June’s update and this is no doubt due to the increase in price for 7 of the coins in the tracker.

After an impressive spike in our last update, we’ve seen another increase in January – taking it to the highest we’ve seen since the Tracker started!

My coin isn’t on the eBay Tracker

The eBay Tracker follows the movements of the Top 10 UK coins and banknotes, however if your coin doesn’t appear on the tracker you can use our 6 point guide to help determine realistic a value for your coin.

So now that you’re up to date with our latest eBay Tracker, will you be selling any of the coins in your collection or will you continue to save them? Let us know in the comments below.

How does the eBay Tracker work?

The Change Checker eBay Tracker takes the last 9 sold prices achieved on eBay and gives the median price achieved (rounded to the nearest 50p). By taking the median, rather than an average, we avoid skewing created by one or two excessive prices achieved.

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.


If you’re interested in coin collecting, our Change Checker web app is completely free to use and allows users to:

– Find and identify the coins in their pocket
– Collect and track the coins they have
– Swap their spare coins with other Change Checkers

January 2019 eBay Tracker Update

The A-Z of Great Britain 10p coins have been a firm favourite with collectors since they were first released in 2018, with 26 Quintessentially British designs capturing the public’s imagination.

Unsurprisingly, some designs are proving more popular than others, but which ones are likely to fetch the most on the secondary market?

We’ve done the hard work for you by taking a look at which A-Z 10p coins are selling for the most on eBay and which ones you should be looking out for.

The Ones to Watch…

If you’re lucky enough to have the ‘A’ for Angel of the North 10p in your collection, you might want to keep hold of it as it currently sells for around £4.20 on the secondary market – over 40 times its face value!

Despite dropping down our August A-Z 10p Scarcity Index, now sitting at the lower half of the index, the ‘B’ for Bond 10p could still fetch you around £3.90!

The N for ‘NHS’ 10p has also increased in value on the secondary market, which comes as no surprise as it also climbed to top spot on our Scarcity Index in May. In recent months, perhaps more than ever, the NHS has played a vital role in keeping us safe and this 10p acts as a reminder of the strength, hope and support of our National Health Service.

How Many A-Z 10ps Are Out There?

In 2019 it was confirmed that there were only 220,000 of each individual design released into circulation in 2018. We know that there were 2.1 million coins issued for 2019 but we’re yet to find out the individual mintage figures for each design.

When the official figures are released we could well see some of these coins increasing in value on the secondary market due to their low mintage!

These coins are notoriously tricky to find, but have you been lucky enough to come across any in your change? Let us know in the comments below.

*** UPDATE ***

With the impact of Covid-19 meaning less people are using cash, it seems older, paper banknotes aren’t being cashed in! According to reports, 24.5 billion paper banknotes are still out there!

Whilst the paper £20 is technically still legal tender, the new polymer notes have been causing quite a stir in the collecting community.

Back in 2016, the first-ever polymer banknote was issued to replace the paper £5 note, with a cleaner, safer and stronger alternative.

Since then, we’ve seen the introduction of the polymer £10, featuring the portrait of Jane Austen and this year saw the issue of the polymer £20 note, featuring JMW Turner’s portrait.

We’ve seen the £5 and £10 notes prove incredibly popular with collectors, with particular notes selling on eBay for way over face value!

But what makes a banknote collectable? Well… It’s all to do with serial numbers!

We previously listed the serial numbers that you should be looking out for on the Polymer £20 note, from AA01 to AK-47, and unsurprisingly, some are proving more popular than others, but which ones are likely to fetch the most on the secondary market?

Well, we’ve done the hard work for you by taking a look at which polymer £20 note serial numbers are selling for the most on eBay and which ones you should be looking out for.

How much is the polymer £20 worth?

Recurring numbers

If you’ve been lucky enough to find a £20 note with a series of recurring numbers, like the 777777 serial number, you may want to keep hold of it as we’ve seen some which are currently selling on eBay for around £400 – over 20 times its face value!

Similar serial numbers have sold for prices within the same range. The 333333 serial number also sold for £400, so it seems collectors everywhere are desperate to get their hands on a recurring number note!

Another type of serial number you should be keeping an eye out for, is a ‘ladder’. These are serial numbers that have consecutive numbers, like this ‘001122’ note.

One lucky collector got his hands on this note but at a hefty £529…  Other ladder numbers include ‘012345’ and these could currently fetch you a very respectful £350 on the secondary market!

AA numbers

As with previous polymer note issues, the lower serial numbers for the new £20 have proven popular with collectors, with the current average selling price for the AA notes coming in at £40! That’s two times the note’s face value!

At the annual Bank of England charity auction held at Spink and Son Ltd in London the very first polymer note, the £5, with the serial number AA01 000017 auctioned for £4,150! However, this year, the £20 note with serial number AA01 000010 sold for a staggering £7,500, over FOUR times its starting price!

AK47

Considered collectable due to the machine gun connotations, polymer notes with the prefix AK47 were thought to be worth well over face value following the new £5 release in 2016.

A quick look at the most recent eBay sold prices for this serial number, on the new £20 note, show that people are willing to pay £11 over its face value!

What about the £50 note?

The Bank of England will be issuing a new polymer £50 in 2021 featuring the scientist Alan Turing.

We can’t wait to see the new polymer £50 when it’s issued!

So there we have it, the current selling prices for your polymer £20 notes! With less cash being used during the current climate and therefore less notes in circulation, it’s possible this has added to the collectability of these new polymer £20 notes.
