added by archaeologs In law, treasure found hidden in the ground etc. but of unknown ownership. In Britain, treasure troves are the property of the State, though sometimes they are in part returned or recompensed to the owner of the land. To be declared treasure trove by a coroner's inquest, the items must be of gold or silver, must have been lost or hidden with the intention of recovery, and by someone who is no longer traceable. In these circumstances, the Crown takes possession, rewarding the finder with the market value or with the object itself if it is not required for the national collections.
