The old £10 notes must be spent by March next year after the Bank of England revealed the date for when they will cease to be legal tender.
A use by date of March 1, 2018, has been slapped on £10 paper notes following the introduction of the plastic tenner on September 14.
Old notes can still be spent ahead of the cut-off date, or exchanged at the Bank once this point has passed.
When was the old bank note first introduced?
The Bank introduced the paper £10 note featuring naturalist Charles Darwin on November 7, 2000.
About 55 per cent of the £10 notes in circulation are made from polymer, while 359 million are paper.
What's different about the new £10 note
The new £10 banknote, featuring a picture of author Jane Austin, is the first Bank of England note with a tactile feature to help blind and partially-sighted users.
Like the £5 note already in circulation featuring Sir Winston Churchill, the new £10 banknote is made from polymer, which is more durable and expected to last five years in total.
