It is one of four of the new £5 notes which micro-engraver Graham Short has adorned with a tiny portrait of Jane Austen.
It was today revealed that the first note had been spent at a café in Blackwood, south Wales, at the end of last week.
Mr Short, who famously engraved the Lord’s Prayer on the head of a pin, made his Austen portraits just 5mm in size.
Located next to Sir Winston Churchill and Big Ben on the polymer notes, the portraits are visible to the naked eye but require a microscope to see properly.
Art experts have estimated that the four notes could be worth up to £50,000 after notes with significant serial numbers such as AK47 sold for similarly eye-watering sums.
The 70-year-old artist told Mail Online: 'I'm always looking to do something different and as soon as I saw the new £5 note I thought 'wouldn't it be good if I could engrave something on it?'
Four rare new £5 notes have gone into circulation, each engraved with tiny portraits of Jane Austen. The 0.2ins (5mm) images were engraved by 70-year-old artist Graham Short and appear on four notes with consecutive serial numbers (AM32 885551, AM32 885552, AM32 885553 and AM32 885554). They also include quotes from three of Austen's novels - Emma, Pride and Prejudice and Mansfield Park.
“I've no idea how much they will be worth but £20,000 is a conservative estimate - previous pieces I've done have been insured for more than £50,000 and the last work, the portrait of HM The Queen on the eye of a needle fetched £100,000.
“So, we came up with the idea of putting a note into each of the countries and I had a nice trip to Blackwood last week to spend one in the Square Café. Now, I'm just hoping someone finds it in time to get some extra money for Christmas.”
