You might want to check your fivers to see if it’s got this picture of Jane Austen on it – it’s worth £50,000.
Just four of them were made and there’s only one left yet to be discovered.
The engraving was put on the note by accalimed artist Graham Short who spent each of the four fivers in England, Scotland, Wales and Northern Ireland.
The third one to be discovered was given to charity in Enniskillen, Northern Ireland.
The engrving shows a picture of the author along with one of her well-known quotes.
Mr Short confirmed the note was legit after the woman sent it to him at The Tony Huggins-Haig Gallery in Scotland.
She told the gallery at her ‘time of life’ she did not need the note and asked them to use it to help people.
The Tony Huggins-Haig Gallery, which came up with the inscription project, has since decided to auction the fiver and donate the money to Children in Need.
It will also create another special note that will be included in the sale.
Mr Short created four £5 notes in 2016 that had the special inscriptions that could not be viewed by the naked eye.
So far three have been found.
The final note’s serial number is: AM32 885554.
