Philip the Arab - Felicitas, Rome or Antioch

Do you know how to distinguish this issue between the mints of Rome and Antioch?

I got this Antoninianus in a multiple lot. The flip it came with says Antioch, but after researching numismatic.org I think it is from Rome, like this one:
https://numismatics.org/collection/1948.19.633

AR Antoninianus, Rome (?) 247 AD
21 mm, 3.41 g
RIC IV Philip I, 4; RSC 136; SRCV (2000 Ed.) 8946;

Ob.: IMP M IVL PHILIPPVS AVG Bust of Philippus, radiate, draped and cuirassed, to r.
Rev.: P M TR P IIII COS II P P Felicitas standing to l., holding long caduceus in r. hand and cornucopia in l.





Very grateful for any info

A French collector made this observation a few years ago that on this type (with Felicitas reverse) from Antioch, the hair lines are parallel with the crown; while on Rome they are perpendicular.



By this method, yours is from Rome. Antioch issues are also much rarer than the Rome issue.
