Help ID: Roman(?) Thunderbolt [opgelost]

Forum, 

Not sure what the obverse is supposed to be but the obverse is a thunderbolt. Tried to check it as Pseudo-autonomous but with no luck. 

19mm, 6,2g

I remember a seleucid coin with that thunderbolt: N#134297 .

Just need to check the letterings if they're the same (I'm not 100% sure they are as it's very worn), but the measurements are close.

That is a good match, I can certainly read the second row as “ANT” and likely “BAΣ” on the first.
