objects that are not treasure or treasure trove are encouraged to voluntarily report them under the Portable Antiquities Scheme to finds liaison officers at county councils and local museums. Under the scheme, which started in September 1997, the officers examine finds and provide finders with information on them. They also record the finds, their functions, dates, materials and locations, and place this information into a database which can be analysed. The information on the findspots may be used to organize further research on the areas. Non-treasure finds remain the property of their finders or landowners, who are free to dispose of them as they wish. On 5 July 2009 the largest single Anglo-Saxon hoard as of that date, consisting of over 1,500 gold and precious metal pieces, helmets and sword decorations tentatively dated to around AD 600–800, was discovered by Terry Herbert in Staffordshire, England.

As at August 28, 2019, the Avon Coroner is yet to rule on the find. The hoard has been described as extremely significant by experts, including the curator of medieval coinage at the British Museum. Avon and Somerset council has expressed a desire to obtain the collection for display in Bath, if it is declared treasure. Scotland The Treasure Act 1996 does not apply in Scotland, where treasure trove is dealt with under the common law of Scotland. The general rule that governs bona vacantia ("vacant goods")—that is, objects that are lost, forgotten or abandoned—is quod nullius est fit domini regis ("that which belongs to nobody becomes our lord the king's [or queen's]"), and the law of treasure trove is a specialized application of that rule. As in England, the Crown in Scotland has a prerogative right to treasure trove for it is one of the regalia minora ("minor things of the
