This coin may be rare then most as the obverse looks like ric 154 to 157 displaying full drapery as this coin, as opposed to ric 162.1, 162, and 163 which is the classification of this coin given the back being Mars holding spear and shied.

There is no full dress in the latter category which it belong as the bust in those even on excellent examples are fractionally draped.

Which would contribute to the obverse die being used from a former example.

Technically it would be an old time human striking error presumedly making this coin an anomaly.

Research records yourself and come to your own conclusion.

I would also conclude this coin was struck between 103-104 AD making it RIC. 162.1 reference strike.
