With a setting on my T2 of 75 18 2+ ground grab these finds were made among lots of nails.The Dolphin brooch dates from A.D.43 to 58 sill has some silvering also complete with its pin. Then the lovely Trumpet brooch found complete with a patina to die for dates Mid 1st to late 2nd century A.D. Then SILVER a denarius of Hadrian with a reverse of Hadrian clasping hands with Roman, minted in Amiens France.The soil on this UK site is very kind to metal.The T2 sorts the nails from the coins no matter how small some are only 1cm diameter very late 4th century
