What's the reference number for this
type (e.g.,
RIC)? I don't know that much about coinage of
Trajan, but is it usual for them to be dated with the
COS on both sides? Looking at
his other
Dupondii on
OCRE, I usually see it on the
obverse OR the
reverse, but never on both sides. (I see some with TR P on the
obv. &
COS rev., but not
COS /
COS, even if they are in agreement.)
If I'm right about that, and it's authentically ancient (and not
tooled), it would make me think this is an unofficial issue or
mule....
