Mr Hammond's recent note on treasure trove examined the decision of Mr Justice Dillon in the case of Attorney-General of the Duchy of Lancaster v. G. E. Overton (Farms) Ltd [1981] Ch. 333 (hereafter Overton). That decision has been affirmed by the Court of Appeal [1982] 2 WLR 397. It is therefore now settled, first, that the law of treasure trove does not apply to any metal other than gold and silver and, secondly, that a treasure trove object must contain a 'substantial' amount of gold or silver.
