September 14th saw the launch of the new £10 note featuring Jane Austen, the only woman to appear on an English bank note.
The new £10 note has been put in to circulation by the Bank of England and is a polymer note, like the recently introduced £5 note.
Paper banknotes are slowly being replaced by plastic notes, which are more secure and resilient to counterfeiting, more resistant to dirt and more durable. The new £10 is expected to last at least 2.5 times longer than its paper predecessor – around five years in total, according to the Bank of England.
The old £10, which has the face of Charles Darwin on it, will be gradually phased out, so you can still use them for now and shops will have to accept them.
They will be officially withdrawn from circulation in spring 2018 - but the Bank of England will issue a warning at least three months ahead of the actual date.
In the period in between, the Bank will gradually withdraw the old notes, replacing them with new ones.
After the old note is withdrawn, the Bank of England said: "Genuine Bank of England notes that have been withdrawn from circulation retain their face value for all time and can be exchanged at the Bank of England."
Anyone who wants to exchange them at the Bank of England can do so in person
Those who want to exchange their old notes for shiny new ones can also do so at their high street bank. Just take them in to any counter and ask to swap them. It's up to each bank whether they exchange the notes for non-customers.
A new polymer £20 banknote will be issued in 2020 with the new note featuring the face of British artist JMW Turner.
It has been recently announced that a new polymer £50 will be launched too, featuring Matthew Boulton and James Watt, who manufactured steam engines during the 18th and 19th centuries.
