Everything you need to know about Polymer Banknote Serial Numbers

The new King Charles III banknotes entered circulation on 5th June 2024, and whilst the reverse designs remain unchanged, this is the first time we’ve ever seen a King feature on UK banknotes – as they were introduced well into Queen Elizabeth II’s reign.

It’s not that long ago, however since we last saw a major change in our banknotes, with the introduction of the first polymer banknotes in 2016. The polymer notes were issued to replace paper banknotes with a cleaner, safer and stronger alternative, and by 2022, all banknote denominations had been replaced with a new polymer version and the older paper notes were withdrawn from circulation.

The new polymer notes caused quite a stir, with collectors rushing to secure the notes with the lowest serial number. But what happened to the very first notes of each denomination?

£5 Polymer Banknotes

Whilst collectors were on the hunt for polymer £5 banknotes with low serial numbers when they first entered circulation in 2016, the very first ones never actually made it into circulation.

The Bank of England always 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, or who traditionally receive a note when a new series is issued.

AA01 000001 – Her Majesty The Queen

The Bank of England also conducted an auction of low serial numbered £5 notes on 3 October 2016, which raised £194,500 to be split between three charities – The Myotubular Trust, The Lily Foundation and Bliss. 

The lowest polymer £5 note with the serial number AA01 000017 sold for £4,150!

It’s also worth looking out for banknotes with serial numbers that could be considered collectable, such as AK47 due to the machine gun connotations, and 007 which could be desirable to James Bond fans.

£10 Polymer Banknotes

The UK’s first polymer £10 note, featuring Jane Austen on the reverse, entered circulation on 14th September 2017, and, similarly to the £5 note, the first ones printed were donated.

In October 2017 some of the first Jane Austen Polymer £10 notes were auctioned and raised a staggering £260,900 for charities Candelighters, Haven House Children’s Hospice and Macmillan Cancer support.

The £10 note with the lowest serial number AA01 000010 sold for an incredible £7,200.

Other notes that fetched hefty sums were AA01 000011 and AA01 000014, selling for £5,200 and £3,500 respectively.

£20 Polymer Banknotes

Issued in 2020, the £20 was the third polymer banknote denomination to enter circulation.

Did you know? The letters at the beginning of a banknote’s serial number indicate its position on the sheet on which it’s printed. The 6 numbers that follow the letters refer to the number on the sheet the note is printed on.

With the £20 note being larger than the £5 and £10 notes, less notes were printed per sheet, however there were still an incredible 59,940,000 notes with an serial number starting AA!

As the polymer £20 note featured JMW Turner on the reverse, some serial numbers matching key dates relating to the painter the became highly collectible.

For example, 23 041775 represents Turner’s date of birth, whilst 19 121851 relates to his death and 17 751851 would be his birth and death combined.

True Turner fans might also look for 18 381839 representing the date he painted ‘The Fighting Temeraire’ (which featured on the new £20 note) and the date the painting was exhibited at the Royal Academy respectively.

£50 Polymer Banknotes

On the day that would have been Alan Turing’s 109th birthday (23rd June 2021), The Bank of England issued their final banknote in the polymer series, celebrating the famous scientist and mathematician.

As is tradition, Queen Elizabeth II received the very first polymer £50 note printed with the serial number AA01 000001, however AA01 000010 was donated to the Turing family in honour of Alan Turing featuring on the reverse of the £50 note.

Again, certain serial numbers matching key dates relating to Alan Turing became collectable, such as 23 061912 which represents Turing’s date of birth, 07 061954 which relates to his death and 09 071941 which represents the date that the enigma code was cracked by Turing and his team at Bletchley Park during WW2.

Queen Camilla represents King Charles III at this year’s Royal Maundy Service

Maundy Thursday is an Easter tradition dating back to 1622, when Charles II was the reigning monarch. The tradition usually involves the monarch gifting members of the public coins as part of a special ceremony, however this year will be a bit different…

On behalf of The King

The annual Royal Maundy Service will take place today at Worcester Cathedral, where Her Majesty The Queen will be distributing the Royal Maundy gifts on behalf of His Majesty The King.

Queen Camilla will be accompanied by Lord High Almoner, Bishop John as the gifts are presented. He said: “It is an honour to be able to welcome HM The Queen to Worcester. This is an immensely special service and I know it will mean a huge amount to those who have been chosen to receive the coins, all of whom will have given years of service to their local communities.”

This isn’t the first time the Maundy Service has been hosted by someone other than the reigning monarch. In 2022, King Charles (then Prince) represented Queen Elizabeth II at the Royal Maundy Service at St. George’s Chapel, Windsor. It was believed to be only the fifth time during her reign that Queen Elizabeth II did not attend the service, including its cancellation due to Covid in 2020 and 2021.

What coins are awarded?

Ceremonial coins will be presented to 75 men and 75 women specially chosen in recognition of the service they have given to the Church and local community.

Each recipient will be gifted two small leather string purses – one white, one red. The red purse contains ordinary coinage as money (in lieu of the food and clothing that was offered years ago), and the white purse contains specially minted silver Maundy coins with a collective face value of 75p (representing The King’s age).

Last year, among the coins in the red purse were the 2023 King’s 75th Birthday £5 and the 2023 Windrush Generation 50p – both of which featured in the 2023 Annual Coin Set. Considering this, it’s possible that commemorative coins from the 2024 Annual Coin Set may be included in this year’s offerings.


The History of Royal Maundy

Maundy Thursday is a key day during the Easter week which commemorates Jesus Christ’s last supper on the day before his crucifixion.

The Royal Maundy Church service takes place each year on this day, and is inspired by the generosity shown by Jesus in washing the feet of his disciples shortly before his death.

Its origins can be traced back to the Middle Ages, when English monarchs would wash the feet of beggars and offer gifts of food and clothing in imitation of Jesus.

However it was King John who was the first to give to the poor on Maundy Thursday and by the early 14th century, it had become customary for the sovereign to provide a meal, together with gifts of food and clothing.

Sharing the Wealth

For numismatists, the day has added significance in the form of Maundy money, which is given out by the reigning monarch each year at the service.

The tradition of giving out money began with Charles II, with the first set of Maundy coins consisting of a four penny, three penny, two penny and a penny. The coins have remained in much the same form since then, and are traditionally struck in sterling silver.

A History of Britannia on UK Coinage

The allegorical figure of Britannia has had a presence on our coins from as early as the Roman era, to as recently as the end of Queen Elizabeth II’s reign. Let’s take a closer look into the history of Britannia on our coinage, and why some coins she features on may be worth keeping an eye on!

Britannia’s debut on coins

Britannia is a fictional representation of Britain itself, and first appeared on our coins in Roman times.

This original interpretation of her can be seen wielding a spear and a shield on the rocks, and was created during the reign of Emperor Hadrian all the way back in 119 AD. She remained on Roman coins for some time, but later vanished from our coinage for 1,532 years!

A millennium later

In 1672, King Charles II brought Britannia back to lift the nations’ spirits. Seen over the waves, she keeps a spear in one hand, but this time holds an olive sprig in the other, as a symbol of peace. The shield remains, perched at her side, but it’s now embellished with the union flag.

At this point in time, the work of the navy was especially crucial in securing power, trade and success, and Britannia’s image became an emblem of Britain’s maritime prowess. This was further cemented by iterations of Britannia from 1797 onwards showing her with a trident in her left hand instead of a spear.

Her portrait changed once again in 1825, where she can be seen facing the opposite way, with the addition of a Roman helmet, a nod to her origins on Roman coins

Many monarchs featured Britannia consistently on their coinage after her reintroduction in 1672 until 1971, mostly on bronze or copper coins. In 1987, her likeness was even used for gold bullion coins by the Royal Mint.

Britannia on UK decimal coins

Since it’s decimal introduction in 1969, Britannia could be found on definitive 50p coins all the way up to 2008, when her portrait was replaced by the Royal Shield design. This change caused an uproar within the coin collecting community and beyond, and even lead to a petition, as many felt she should remain on our 50p coin.

After a small break from circulating coinage, Britannia made a triumphant return as the face of the definitive £2 coin which was released in 2015. 

2016 Britannia £2

The rarest definitive £2

This coin would go on to become the rarest definitive £2 coin to date, with the 2015 Britannia £2 coin securing a mintage of only 650,000! But why were so few minted?

Well both Technology and Britannia designs entered circulation in 2015, and with a massive 35,360,058 Technologies minted, there wasn’t the demand for a large amount of Britannias. The following year, only 2,925,000 Britannia £2s were minted, but after that, we didn’t see any new ones in our change until 2021 and 2022.

2015 Britannia £2
The 2015 Britannia £2 has a mintage figure of just 650,000

According to our most recent eBay Tracker, a 2015 dated Britannia £2 can fetch you as much as £6.24 on the secondary market, that’s over x3 its face value!  

There is also an error version of this coin you can look out for, where the portrait on the obverse of the coin is misaligned by a 150 degree angle! 

The 2015 £2 isn’t the only rare coin to feature Britannia however – as the 2008 Britannia 50p has a mintage of just 3,500,000 – which is far less than previous years! The mintage was so low in fact, that it brought down the average of the Britannia 50p as a whole, causing it to become ‘Less common’ on our Scarcity Index. 

Will we see Britannia again?

Do you have any coins featuring Britannia in your collection? Perhaps you even have one of the rare or error versions of these coins, comment below!

This year, we can expect to see the new King Charles III definitive £2 entering circulation, so I wonder if we’ll see Britannia again on our circulating coins? Let us know what you think…
