Which Alan Turing £50 notes should you be looking out for?

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 Alan Turing £50 Polymer Banknote

The brand new £50 note is full of exciting design and security features, including:

  • 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!

Q&A

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.

The six-sided Diamond Jubilee coin that never was…

Did you know that a special six-sided coin was very nearly released to commemorate one of the most significant celebrations in British history – the Queen’s Diamond Jubilee?

In fact, the coin was so close to being produced that the design was nearly sent off for Royal approval before the proposal was eventually rejected by senior staff at the Royal Mint.

But what could this coin have looked like? Stay tuned as we explore more in this blog…

What the UK’s first 60p could have looked like

A document from Kevin Clancy, secretary to the Royal Mint Advisory Committee, and addressed to the Master of the Mint at the time – Chancellor George Osborne, stated “The proposed coin would be a six-sided bi-colour coin with round of nickel-brass and a shaped outer of cupro-nickel.”

The document also stated: “It is recommended that an entirely new denomination coin – a 60p piece – should be produced to commemorate the 60 years of Her Majesty’s reign”.

Whilst the coin was proposed to be a commemorative-only issue and wouldn’t enter circulation, the idea for the coin was abandoned all together, as papers from the Royal Mint Advisory Committee revealed the commemorative coin programme was already ‘sufficiently comprehensive’.

This programme in question of course ended up bringing us the stunning 2012 Diamond Jubilee £5 Coin.

This was the first coin ever to be struck to commemorate a Diamond Jubilee – there were no special coins for Queen Victoria’s in 1897!

The obverse featured a new portrait of Her Majesty crowned and wearing the robes of the Order of the Garter, created especially for the Diamond Jubilee by Ian Rank-Broadley.

Also designed by Ian Rank-Broadley, the obverse features a portrait of the young Queen Elizabeth just as she appeared in her first portrait with the Latin words DIRIGE DEUS GRESSUS MEOS (May God Guide My Steps).

This £5 isn’t the only remarkable issue we’ve seen commemorating Her Majesty’s Jubilees…

1993 Coronation 40th Anniversary £5

1993 Coronation 40th Anniversary £5.

This £5 coin was issued to mark 40 years since the Queen’s coronation in 1953 – her Ruby Jubilee.

The obverse features the original portrait by Mary Gillick placed in a circle surrounded by eight mounted trumpeters of the Household Cavalry separated by swords and sceptres.

The reverse features the Crown of St Edward which was used at the Coronation, set within 40 radiating trumpets.

The words FAITH AND TRUTH I WILL BEAR UNTO YOU, from the Coronation oath, are inscribed at the top, with the double dates 1953 and 1993 appearing at the foot.

In 2002, to mark the 50th anniversary of the Queen’s accession to the throne, the Royal Mint produced this £5 coin.

On one side appears an unusual bust portrait of the Queen wearing the robes of state. The dramatic impact of this motif are heightened by the absence of any inscription other than the value in small lettering around the foot.

The reverse design, as with the original Coronation crown of 1953 features the Queen on horseback. The Latin motto AMOR POPULI PRAESIDIUM REG(inae) meaning ‘The love of the people is the Queen’s protection’ was last used on the coinage of Charles I.

The Queen’s Platinum Jubilee in 2022

In 2022, Her Majesty will celebrate her Platinum Jubilee, after a magnificent 70 years of service to the throne.

According to the Government website, plans are already in place to mark this anniversary, including collaborations with “some of the UK’s leading creative minds, event organisers and world class digital design companies”.

In keeping with tradition, a Platinum Jubilee medal is said to be awarded to people “who work in public service including representatives of the Armed Forces, the emergency services and the prison services.

This tradition stretches back to the reign of Queen Victoria when an official medal was designed to mark her 50th anniversary on the throne”.

Whilst there has been no official confirmation of a Platinum Jubilee commemorative coin in the works, we’re certainly going to keep our fingers crossed that this magnificent anniversary will be celebrated on our UK coinage.
