This image features two views of an ancient, weathered coin against a black background.

  • Left view: Displays the obverse (front face) of the coin with the faint outline of a portrait, likely depicting a historical or mythological figure. The details of the face and features are difficult to discern due to corrosion and age. Shades of green patina and brown tarnish dominate the surface.

  • Right view: Shows the reverse (back side) of the coin. This surface appears to have a faded scene or object that is barely recognizable. Like the obverse, it shows a similar corroded and tarnished texture, with shades of green and brown.

A scale bar labeled in centimeters is visible at the far right, indicating that the object is small in size, typical of ancient coins. Its aged appearance suggests it might have been exposed to environmental conditions that caused oxidation and wear over time.
