This is probably an ancient copy of a late Roman coin. It is quite small. Size is 10.5 mm / weight is 0.63 g. I am not actually new here, my old accout name was Coinprinses. But for some reason I am unable to renew my password. Hence a new account.
Sure enough. The style and module are effectively all you need. And the reverse looks as if it's from a 4th-century prototype; as a guess, it might be as late as 5th century. From what I know, these show up in the UK, Germany, France (/Gaul) and North Africa (sometimes Vandals). There are some mavens here, who are likely to be of more help with the chronology and geography.
