The Secretary of State (currently meaning the Secretary of State for Culture, Media and Sport) may direct that any such treasure be transferred or disposed of, or that the Crown's title in it be disclaimed. The Act uses the term treasure instead of treasure trove; the latter term is now confined to objects found before the Act came into force.

Treasure does not include unworked natural objects, or minerals extracted from a natural deposit, or objects that have been designated not to be treasure by the Secretary of State. Objects falling within the definition of wreck are also not treasure. Coroners continue to have
