Philip I, Philip the Arab, 244-249 A.D., sestertius, R.I.C. IV, 173a. The obverse shows bust of Philip I, draped, laureate, cuirassed, facing right. The obverse legend is "IMP. M. IVL. PHILIPPVS AVG". The reverse shows Fides, draped, standing left, holding a standard in the right hand, and a transverse sceptre in the left hand. The reverse legend shows "FIDES MILITVM S C ". Both sides are dark brown to near black in color, and have varying irregularity over the surfaces. The piece is listed here as a sestertius rather than a dupondius, because though it is a light sestertius (and they varied quite a bit in weight), at 13.9 gms, that puts it well above the typical heavier weight that show up on the dupondius. Also, I could not see that Philip was wearing a radiate crown. The diameter is 28-30 mm, based on the less than round shaped so commonly seen. This is a genuine, original coin, not a copy, replica, or reproduction.
