Treasure was found in West Yorkshire twice last year - what you must do if you find treasure

The Institute of Detectorists said finding treasure gives historians a valuable insight into the past, but encouraged hobbyists to practice "responsible" metal detecting.

Figures from the Ministry of Justice for 2021 show there were two finds reported to West Yorkshire Coroner's Court, which is responsible for holding treasure inquests.

This was up from one the year before – ​and among 14 found in the area since records began in 1995.

Across England and Wales, 908 finds were reported last year – 13% more than the year before, but still below the record 1,061 found in 2019.

The Treasure Act, introduced in 1997, defines treasure as discoveries older than 300 years.

These include coins, prehistoric metallic objects and artefacts that are at least 10% precious metal such as gold or silver.

All potential treasure finds are processed by the British Museum, whose experts advise coroners on whether the find fits the definition of treasure.

If a coroner rules that it is treasure, both local and national museums are given the chance to acquire the pieces, and the finder will be paid a sum depending on the treasure's value.

But if the find is determined not to be treasure, or no museums want it, then it is returned to the treasure hunter.

The MoJ said the number of finds increased steadily from 1997 but since 2018 the trend has been more volatile.

It said the rise in the number of finds from 2020 to 2021 is likely due to the easing of coronavirus pandemic restrictions.

Keith Westcott, founder of the Institute of Detectorists, said: "Beyond the fascination which surrounds treasure and monetary rewards, is an important value of detecting finds – a historical value which provides a valuable insight into our past.

"Often though, the archaeological record which surrounds the find, the information that gives it context, is damaged or ignored."

He encouraged amateurs to follow responsible metal detecting and leave important finds in place ready to be excavated by archaeologists.

Anyone who discovers something they think is treasure must report their finding to the coroner within two weeks, so the court can hold an inquest to decide who should get to keep it.

Failure to do so can result in an unlimited fine or up to three months in prison.
