The new polymer £10 notes are entering circulation on Thursday - but some could be worth more than you think.

The new notes, which will feature Jane Austen, already have collectors getting excited about serial numbers.

According to changechecker.org, a £5 polymer bank note which had the serial number AK37 007 and became known as the James Bond banknote sold for £5000 – 1,000 times its face value.

Any £10 notes with the AA serial number are expected to be popular and there are a lot of combinations so there should be a high chance of getting one.

However, the Bank of England will hold some back, for example the Queen receives AA01 000001 and the Churchill War Rooms received a new £5 note with serial number AA01 001945 - the date Second World War ended.

While the serial numbers JA01 and JA75 - Jane Austen’s birth year - and JA17 - the year of Jane Austen’s death - may also prove popular, it could take many years before the notes enter circulation.

The £5 note with the lowest serial number available to the public - AA01000017 - sold for £4,150 at auction in October last year.

According to Changechecker.org, you should look out for:

  • The serial numbers 16 121775 and 18 071817 as they represent the author’s date of birth and death.
  • The serial number 17 751817 as it’s her birth and death combined The 28 011813 as it’s the date when her most celebrated novel, Pride and Prejudice, was first published.
