It's a modern replica of a coin of Roman emperor Claudius, although "replica" is too generous of a word. Sorry . Here's an authentic example from CNG's archives: CLAUDIUS. 41-54 AD. Æ As (28mm, 10.86 gm). Rome mint. TI CLAVDIVS CAESAR AVG P M TR P IMP P P, bare head left / CONSTANTIAE AVGVSTI, S-C across field, Constantia standing left, raising right hand and holding spear in left. RIC I 111; BMCRE 201; Cohen 14. VF, nice even brown patina, light smoothing in fields.
The pictures are out of focus and I can't tell what the metal/color is, but it is also a Roman coin (or more likely, a replica) but of a much later time in the Roman Empire. Try taking better pictures. Have your phone camera perfectly flat to the surface of the coin. Keep the camera far enough away to allow your autofocus to work.
