The artist embellished four notes which he made a decision to put into circulation in each of the four countries in the UK.
She has said that she isn't seeking to release its value at this stage.
She wants to remain anonymous but plans to give the fiver to her granddaughter to invest for when she grows up.
Granny Jean's Home Bakery in the Roxburghshire town had a flurry of interest from hopeful people who turned up after it emerged the special fiver featuring a tiny portrait of Jane Austen had been spent there.
Artist Graham Short created the custom fivers, adding small etchings of Jane Austen onto four of the new flexi polymer £5 notes, then spending them in a variety of locations to get them out into the public domain.
Each note is also engraved with a unique Jane Austen quote, with this one stating "a large income is the best recipe for happiness I ever heard of" from Mansfield Park.
Mr Short engraved four notes and spent one each in Wales, England, Scotland and Northern Ireland.
The chances of getting one of the notes is tiny - but the easiest way to confirm if you do have one is to check the serial number. A microscope is needed to see the images clearly.
Art experts estimate the fivers could be worth up to £50,000 after collectors forked out thousands to buy notes with unusual serial numbers.
Graham previously hit headlines when he engraved the words of the Lord's Prayer on the head of a pin.
"When I saw the new £5 note, I thought, 'Wouldn't it be good if I could engrave something on it".
When asked about why he did it, he said because "next year is the 200th anniversary of her death and her image will be on the new £10 note".
The minuscule engravings are only visible in certain light, meaning they are easy to miss.
Graham has been engraving for more than half a century after starting an apprenticeship when he left school at the age of 15.
"But previous pieces I have worked on have been insured for more than £50,000".
