Treasure trove is an amount of money or coin, gold, silver, plate, or bullion found hidden underground or in places such as cellars or attics, where the treasure seems old enough for it to be presumed that the true owner is dead and the heirs undiscoverable. An archaeological find of treasure trove is known as a hoard. The legal definition of what constitutes treasure trove and its treatment under law vary considerably from country to country, and from era to era.
