owned. If the person who had hidden the treasure was known or discovered later, it belonged to him or her or persons claiming through him or her such as descendants. To be treasure trove, an object had to be substantially – that is, more than 50% – gold or silver. Treasure trove had to be hidden with animus revocandi, that is, an intention to recover it later. If an object was simply lost or abandoned (for instance, scattered on the surface of the earth or in the sea), it belonged either to the first person who found it or to the landowner according to the law of finders, that is, legal principles concerning the finding of objects. For this reason, the objects found in 1939 at Sutton Hoo were determined not to be treasure trove; as the objects were part of a ship burial, there had been no intention to recover the buried objects later. The Crown had a prerogative right to treasure trove, and if the circumstances under which an object was found raised a prima facie presumption that it had been hidden, it belonged to the Crown unless someone else could show a better title to it. The Crown could grant its right to treasure trove to any person in the form of a franchise. It was the duty of the finder, and indeed of anyone who had acquired knowledge of the matter, to report the finding of a potential treasure trove to the coroner of the district. Concealing a find was a misdemeanour punishable with fine and imprisonment. The coroner was required to hold an inquest with a jury to determine who were the finders or the persons suspected to be the finders, "and that may be well perceived where one liveth riotously and have done so of long time". Where there had been an apparent concealment of treasure trove the coroner's jury could investigate the title of the treasure to discover if it had been concealed from the supposed owner, but any such finding was not conclusive as the coroner generally had no jurisdiction to enquire into questions of title to the treasure between the Crown and any other claimant. If a person wished to assert title to the treasure, he or she had to bring separate court proceedings. In the early 20th century, it became the practice of the Lords Commissioners of the Treasury to
