Description: | DescriptionCopper-alloy toggle with flared, cone-shaped terminals.Metal content: copper with approximately 20% arsenic and 10% tin.Weight: 49.92gDiscussionAlthough many parallels for the central section of the toggle can be found, the terminals are unusual as they flare out to form large cones. Nevertheless, based on the construction of the central section, it probably dates to the late Iron Age. Non-destructive X-ray fluorescence indicates that the 'silvery' appearance of the surface of the toggle is in fact caused by high concentrations of arsenic and tin. ConclusionThe artefact is greater than 300 years old but it is not made of precious metal. It is therefore not treasure.Jody Joy Curator of European Iron AgeBritish MuseumGreat Russell StreetLondon WC1B 3DG
