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and by 2022, all banknote denominations had been replaced with a new polymer version and the older paper notes were withdrawn from circulation.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.

Serial number Recipient 
AA01 000001 – Her Majesty The Queen 
AA01 000002 – Prince Phillip 
AA01 000003 – Prime Minister

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.

A Major Change for Canadian Coinage

During her incredible 70 year reign, there have been four different obverse portraits of Queen Elizabeth II used on Canadian coinage. The latest portrait change was in 2003 when Susanna Blunt’s effigy of Her Late Majesty made its way onto Canadian coins.

Considering that the obverse of Canadian coinage hasn’t changed in over 20 years, and the fact that we haven’t seen a King on Canadian coins in 7 decades, the introduction of King Charles III’s effigy is sure to cause a stir in the coin collecting world.

The Process of Creating an Effigy

As you might imagine, there are a lot of steps behind the scenes that go into creating a new effigy…

Canada’s new coin effigy was created from Steven Rosati’s winning design, following an invitation to more than 350 artists and engravers.

The process involved each artist/engraver submitting a portfolio of portrait work to be evaluated. These were then shortlisted before a brief outlining mandatory design requirements was given out.

An internal Mint review panel judged submissions based on aesthetics, technical requirements and mass-production suitability before the winning design was submitted for approval from the government and Buckingham Palace.

Once the design was ready, the Mint could begin the engraving and tooling process – producing dies to strike the coins.

Only 500 available for Change Checkers

A passion for nature

Inspired by King Charles’ passion for nature and conservation, designer Dan Thorne has created a beautiful reverse design on this new UK £5. It includes The King’s royal cypher along with the number 75, all framed within oak leaves and delphiniums. The design was even personally approved by The King himself.

It’s not just nature that His Majesty is passionate about, he also has a keen interest in the arts, architecture and supporting disadvantaged young people. In 1976, when he was His Royal Highness The Prince of Wales, The King founded The Princes Trust, an organisation committed to improving the life of young people in the UK.

He’s also been an avid campaigner for environmental issues and sustainability, living by the principle that it’s better to work with nature than against it.

A closer look

As well as the main aspects of the design such as the plants, royal cypher and the years 1948-2023, there are a few features on the coin you may not have noticed at first glance.

On closer inspection, we can see a ladybird, 4 bees and a dragonfly hidden within the design – another nod to The King’s love of nature.

New UK Coinage for King Charles III

The King’s love for nature and his passion for conservation is also reflected in the UK’s New Coinage. The 8 brand new coins feature designs themed around British wildlife and conservation, whilst the obverses feature King Charles III and a special privy mark.
