I found this among my dad's collection. I posted it in World coins, and received some information as follows: It is the Roman emperor Gratian (367-383 AD). The inscription on obverse reads DN GRATIANVS PF AVG (Dominus Noster Gratianus Pius Felix Augustus) [Our Master Gratian, Pious, Blessed, Augustus). If you post this in the "Ancients" section, others can give you more info. So I am posting in "Ancients Forum" to hopefully gather more information... Thank you for any additional help !
Just posted over on your other thread. This is a good link for you to start looking: http://www.wildwinds.com/coins/ric/gratian/t.html
Looks real porous. Not sure what to make about the authenticity as I'm not too knowledgeable about this time period. But if it turns out to be a genuine Gratian.... Gratian Then you must also get a Valens. These two worked rather well together towards unintentionally destroying the fragile balance between Barbarians and Romans in the 4rth Century. After this lot the question was not if the Roman Empire would fall, but when. The fact that the Eastern Empire managed to last another 1000 years was a miracle. Any betting man at the end of the 4th century would have been smart to bet none of the two halves would survive another century, because that's how bad things looked at that time. Valens
The coin does look quite porous, examine the edge to see if you see a seam where it might have been cast. What is the weight and diameter in mm?
It is about the size of a dime, but much much thinner. Thinner than the depth of the 2x2 holder. The width is 19 mm
I strongly suspect that the coin you showed is a cast copy. It has very obvious casting bubbles, the contours of the design and legends look mushy and not struck, and the toning is very suspicous, too. Hopefully, I'm wrong!
