Hi everyone,
I’d appreciate help verifying an attribution for a Late Roman bronze coin.
Coin details:
- Diameter: 17.55 mm
- Weight: 3.39 g
- Thickness: 2.13 mm
- Slight/weak magnetism (not strongly magnetic)
Attribution (tentative):
Roman Empire, Constantine I era (c. AD 330–335)
City Commemorative AE3 Nummus – CONSTANTINOPOLIS type
Obverse: Helmeted bust of Constantinopolis facing left. Legend is worn but appears consistent with CONSTANTINOPOLIS (partial letters visible such as OP / IS).
Reverse: Victory (Nike/Victoria) standing left on ship’s prow, holding a spear/scepter.
Mintmark (exergue): unclear but may read SMNΔ, which would indicate Nicomedia, officina 4.
If the mintmark reading is correct, the closest match seems to be:
RIC VII Nicomedia 64 (or similar Nicomedia Constantinopolis issue)
Could anyone confirm whether this is the correct mintmark and RIC number, or suggest a better attribution?
Thanks in advance!
