Hello everyone,
I have an ancient Roman bronze or copper coin weighing 3.6 grams and measuring 1.9 cm in diameter.
The reverse type is VICTORIAE LAETAE PRINC PERP, which likely places it in the late Roman imperial period.
It could be a follis or nummus.
- Obverse: Profile bust of the emperor, laureate, helmeted, and cuirassed, facing right. The legend begins with IMP CONSTAN..., but the rest is worn and hard to read.
- Reverse: Two winged Victories, draped, facing each other, holding a shield inscribed VOT / PR on an altar. This refers to imperial vows (Votis Populi Romani) and the celebration of a 10-year reign (indicated by the "X" below).
- Exergue: There is a clear "S", possibly part of the mint mark. There may be additional letters to the left and right, but they are unclear due to wear.
Based on the style and the "S" in the exergue, I suspect it might be from the Siscia mint, possibly catalogued as RIC VII Siscia 47 (???).
Tentative legends:
- Obverse: IMP CONSTANTINVS P F AVG
- Reverse: VICTORIAE LAETAE PRINC PERP
Can anyone help confirm the identification or provide more precise details, considering the coin's worn condition?
