Could your King Charles III Banknote be worth £17,000?

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 the monarch, people or institutions that were involved in the development of the note, but others can fetch hefty sums at auction!

Notes under the hammer

Spink & Sons recently held four auctions for each denomination of the new King Charles III banknotes to raise funds for charity, and a whopping £914,127 was raised overall!

The proceeds from the auctions will be shared between 10 charities that have been chosen by the Bank of England:

  • Childhood Trust
  • The Trussell Trust
  • Shout
  • Carers UK
  • Demelza
  • WWF-UK
  • The Brain Tumour Charity
  • London’s Air Ambulance Charity
  • Child Bereavement UK
  • The Samaritans

At the auction for the King Charles III £10 banknotes, a single £10 note with the serial number HB01 000002 sold for an astonishing £17,000!

The £50 banknote auction even broke the record for the highest lot sold in a Bank of England banknote auction. A sheet of 40 £50 banknotes sold for £26,000 – 13 times their face value!

Which serial numbers should you be looking out for?

Whilst the very first banknotes aren’t released into general circulation, there are other serial numbers that are also considered collectable.

JMW Turner £20 Notes

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

Alan Turing £50 Notes

The £50 note features famous scientist and mathematician, Alan Turing, and similarly to the £20 note, certain serial numbers matching key dates relating to Alan Turing became collectable.

Serial numbers 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) are all ones to look out for. .

Others include AK47, due to the machine gun connotations, and 007 which could be desirable to James Bond fans.

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)

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