Definition of treasure trove to be recast to protect UK's rare artefacts

Recent finds have not met criteria as they are made from bronze, not precious metals

The government plans to change the official definition of treasure" to cover more rare and precious archaeological finds so that such artefacts can be saved for the nation rather than sold to private collectors.

Under the 1996 Treasure Act, objects are designated as treasure trove if found to be more than 300 years old and made of gold or silver, or found with artefacts made of precious metals.
