Several things:
First: please look at the title you gave this
thread. There is no such person as "Gordo the 13th." Accuracy is important here.
Second: As mauseus said, twice, this is a photo of a coin of
Philip I. The
obverse legends prove it:
IMP M IVL PHILIPPVS AVG.
Third: If these two photos are indeed of the same coin, then it would be a coin of
Philip I paired with a die of
Gordian III.
RIC lists about 14 of them on pp. 79-80.
However, the
flan crack above Philip's
head is quite large, and might be visible on the
reverse, which it is not. So I think mauseus is correct.
