Micro-engraver Graham Short has given a surprise to people using the new plastic fiver.

The 70-year-old artist has put into circulation four of the £5 notes, all of which have miniature, hidden engravings of Jane Austen on them.

The notes, which could be worth as much as £50,000, feature the painstakingly engraved design next to the picture of Big Ben and Winston Churchill.

He has also engraved quotes from 'Emma', 'Pride and Prejudice', and 'Mansfield Park' onto the notes.
