A famous engraver etched a tiny picture of Jane Austen on some five pound notes.

Each one is estimated to be worth £50,000, judging by the value of some of his other work.

Across Britain, people checked their fivers to see whether they had one of the four special notes.

The third one has now been found by an elderly Northern Irish woman, and she has kindly donated it to charity.

She sent it back to Graham Short, who engraved the notes, with a note asking him to use it to "help young people".
