On the day that would have been Alan Turing’s 109th birthday, The Bank of England have just issued their final banknote in the polymer series, celebrating the famous scientist and mathematician.
The brand new £50 note is full of exciting design and security features, including:
- A photo of Turing from 1951 which is part of the National Portrait Gallery’s collection,
- A design of Turing’s trial model of his famous Automatic Computing Engine (ACE) Pilot Machine,
- Technical drawings for the British Bombe,
- Ticker tape depicting Alan Turing’s birth date (23 June 1912) in binary code, and
- A large see-through window depicting a metallic microchip image with clovers around the outside in dedication to Bletchley Park, where Turing conducted most of his work in WW2.

Keen collectors will be eager to hunt down the most sought-after serial numbers for the new note.
When the UK’s first polymer £5 note was released in September 2016, serial numbers became the talk of a nation and stories of early serial numbers selling for thousands of pounds were commonplace.
In fact, an “AK37 007 James Bond Bank of England Polymer £5 note” even sold for £5,000 on eBay – 1,000 times its face value!
But as this brand new £50 enters circulation, which serial numbers should you be looking to get your hands on?
AA01 – the first notes to be printed
AA01 are the first serial numbers to be printed and always prove popular with collectors.
Our eBay Tracker follows the prices of the UK’s Top Coins and Banknotes, including the AA01 polymer £5 and £10 notes, which are currently selling for £10 and £15 respectively. However when the notes were first released we saw a collecting frenzy, with people paying (and demanding) vastly inflated prices for low serial number notes.
Prefixes on the £5 notes started at AA and there are 60 notes on a sheet, AA01- AA60. For each of these cyphers there are 999,000 serial numbers printed: 000001 to 999000. Therefore for the first AA cypher there’s an incredible 59,940,000 notes!
Whilst the £50 note is larger than the £5, meaning less notes will be printed per sheet, there are still A LOT of combinations for AA cyphers on the new £50 – so make sure you keep your eyes out for them!
However, The Bank of England will 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.
For example, Bletchley Post Office was one of the first places to have the new £50 note today, in recognition of the the work done by Mr. Turing and his team at Bletchley Park.
Key dates to look out for
It’s always worth looking out for certain serial numbers matching key dates relating Alan Turing that could become collectable.
For example, 23 061912 represents Turing’s date of birth, whilst 07 061954 relates to his death and 19 121954 would be his birth and death combined.
True Turing fans might also look for 09 071941 representing the date that the enigma code was cracked by Turing and his team at Bletchley Park during WW2.
Novelty numbers and Consecutive notes
There may well also be a rush to find the AK47 serial numbers again and James Bond 007 will likely be popular once more.
Consecutively numbered notes are always interesting to collectors too – one man sold three consecutive AA01 notes for £456!
Can you request specific serial numbered notes from the bank?
Sadly not. For the launch of the new £5 note 440 million banknotes were printed and these were printed in very large batches.
To print enough banknotes to service the country’s 48,000 ATMs for example, it’s just not possible for the bank to separate certain serial numbers.
How much should I pay for a new £50 note?
The simple answer is, it’s completely up to you. An early serial numbered £50 note will be a genuine piece of the country’s history. It’s likely The Bank of England will hold an auction of early editions, so if you have the disposable income, why not?!
Will the old paper £50 note still be legal tender?
You will still be able to use the paper £50 note until The Bank of England withdraw it from circulation on 30th September 2022.
Many banks will accept withdrawn notes as deposits from customers. The Post Office may also accept withdrawn notes as a deposit into any bank account you can access at the Post Office. And, you can always exchange withdrawn notes with The Bank of England directly.
Where will I be able to find the new polymer £50 note?
Whilst not all cash points will offer the option to withdraw a £50 note, most banks should be able to provide you with one. It’s worth ringing your local bank in advance to check they have the new note before setting out to collect it.
