Items also declared treasure by Norfolk's assistant deputy coroner David Osborne included an Anglo-Saxon silver pin found in Scoulton, a Middle Bronze Age Gold Bead discovered in Salthouse and a hoard of 59 silver Roman coins that date from the Roman Republic to Tiberius, the second emperor of Rome.
