A small gold bible has been found by a metal detectorist.
Bible
The 600-year-old object, which may have been owned by a medieval aristocrat or royal, was found by NHS nurse Buffy Bailey as she searched farmland near York with her husband Ian.
An expert described the bible - which is just 0.5 inches long - as an "exceptionally unique" artefact that could be worth more than £100,000.
Bailey told BBC News: "I dug down five inches and it was just there - I still didn't believe it was anything special.
"It was so heavy and shiny - just absolutely beautiful."
The object weighs just five grams and is thought to date back to the 15th Century and is engraved with images of St Leonard and St Margaret, the patron saints of childbirth.
It was found on land that once belonged to Richard III and it has been speculated that it could have been owned by one of his female relatives or his wife Anne Neville.
