The Bank of England has confirmed that the old style £10 notes must be spent by the 1st of March 2018.
The notes that feature Charles Darwin were introduced on November 7, 2000. However, it has now been substituted by a polymer version – which gives pride of place to Jane Austen, the renowned author.
The notes became legal tender on September 14, 2017.
About 55 percent of the £10 notes that are currently in circulation are the new version, while the remaining 359 million notes are still made of paper.
The new notes are the first of its kind to have a tactile feature that helps the blind and partially sighted people distinguish the note.
The Bank of England says that the new notes are also an improvement on the earlier version in terms of durability and security.
After the deadline in March, the old notes will only be allowed to be exchanged at the Bank of England.
In May, the old style £5 notes went out of circulation while the old round £1 coin is also no longer considered as legal tender.
