A RARE five pound note, estimated to be worth £50,000 due to a tiny engraved portrait of Jane Austen, has been found in Northern Ireland.

It is one of four fivers printed by Birmingham micro-artist Graham Short and the third to be discovered across the UK, leaving just one more note outstanding.

According to Mr Short, he spent a note in each of the four home nations. The first was found in a cafe in south Wales last December, while the second discovery was made in Scotland in the same month, having been received in a Christmas card.

The third find was made by an elderly lady in ‘Charlie’s bar’ in an undisclosed part of Northern Ireland.

Mr Short came up with the idea of engraving a five-millimetre picture of the author on the transparent part of the new plastic Bank of England £5 notes to mark the 200th anniversary of her death.

He has included a different quote around each one ensuring each note is unique.

The recipients in Wales and Scotland stated in December they intended to keep the notes rather than sell them.

The serial numbers of the notes are AM32 88551, AM32 88552, AM32 885553 and AM32 88554.

The note spent in England is the only one to remain in circulation.
