Roman coin - Constantine? [opgelost]

Hello,
I want to know what this Roman coin but I can’t find a match. The bust seems to be of Constantine or such but I’m far from expert on this. Can anyone help me?

diameter: 13mm
thickness: 0.5mm
weight: 0.88g
metal: bronze?

Hello Cuthwellis,

This is a follis of Théodosius (we can see the letters under the dirt)
with a reverse belonging to the SALVS REI-PVBLICAE type. RIC# 26.

It was minted in Héracléa, as shown by the total absence
of a latin crosse or of a Chi-Rho emblem on the left field.

Regards.

Thank you! Looks like only the Antioch mint one is listed on Numista as yet? I'll see if I can add it.
