Honorius. AD 393-423. AR Miliarense Constantinople mint. 
It does look good, but Not Original

I bought this coin many years ago when I was much more ignorant about ancient coins than I am now, now that I am selling everything I got it out checked into it and realized it is way to lightweight. no examples are even close this one is almost 2 grams light. So now that I consider myself a professional I deem it as not authentic although it does look good. 
The standard weight of this coin is about 4.3 Grams  21-22 MM 
This coins is 2.6 Grams 21MM

Struck AD 395-circa 403.
