The Reverse is upside down, but it is a Fel Temp Reparatio type coin with a Roman Soldier killing a barbarian on a horse. I can't make out a mint, but I think it is Constantius II.. Here is mine Constantius II. Minted in Antioch 350-355 AD
Wow. Your example is in amazing condition. That patina isn't something I see on US coins. Thank you for the information. I figured you folks would know the coin's who, what, where, and when. My buddy was told 69 AD - which sounds incredibly precise now that I think about it.
