Cochran,,,not quite enough info to make a judgement on weather fake or not....But. Roman silver coins were not of particularly high quality control,,I have seen fronts with proper alignment and the rear be half or more off and visaversa. Many silver denarri were regionally produced by the local governor of the territiory,,so there were many many many fakes even in that time. This is why you see somany with hatchet marks. In the market there was a person who chopped the suspect coins to make sure it was silver no matter what the coin was supposed to look like. Many coins from then were also cast verses being pressed with dies. Only the best gold and silver coins used presses and dies. Hope this helps you some. Not really my area of expertice but I have researched a few of my own. Im a silver half and dollar nut mostly.
