The obverse (front) of a late Roman bronze coin, most likely belonging to the Constantinian dynasty (circa 330–348 AD). 

Key Identification Features

• Emperor's Portrait: The bust features a right-facing head adorned with a diadem (a jeweled or pearl-studded headband), which was the standard "crown" of the late Roman period.
• Potential Rulers: While the inscription is heavily worn, this specific portrait style is common for Constantine the Great or his sons, Constantine II, Constantius II, and Constans.

 

 

 

Key Identification Features

• Obverse (Front - Side Shown): Features a right-facing bust of a member of the Constantinian Dynasty. The "crowned" appearance is a diadem, a pearl or jeweled headband that became standard for emperors during this period.
• Likely Emperors: This design was used by Constantine I (the Great) and his sons: Constantine II, Constans, and Constantius II.
• Reverse (Back - Described): Depicts two soldiers facing each other, each holding a spear and shield, with a military standard between them.
• Inscription (Legend): The principal lettering on a coin is called the legend. While your specimen is worn, identifying specific letters in the circular text (like "CONSTANTINVS") would confirm the exact ruler. 

 

 

 

 

The reverse (back) of a GLORIA EXERCITVS bronze coin, featuring two soldiers facing each other.

Key Identification Details

• Central Design: Between the two soldiers, there is a single military standard (a tall banner). This confirms the coin was struck between 335 and 340 AD. Earlier versions from 330–335 AD featured two standards.
• The Inscription: Though heavily worn, the circular Latin text around the edge would originally have read GLOR-IA EXERC-ITVS, which translates to "The Glory of the Army."
• Possible Emperors: This specific one-standard design was issued by Constantine I (the Great) in the final years of his life, and continued by his three sons: Constantine II, Constantius II, and Constans.
