This image shows two sides of an ancient coin against a dark background, with scale markings on the right indicating its size in centimeters. The coin appears to be heavily corroded, with visible patches of green oxidation, possibly due to exposure over time, indicative of copper or bronze content.

The coin's obverse (left) features the profile of a person, likely a ruler or deity, wearing what appears to be a radiate crown. The edges suggest a circular border of dots, a common design in ancient coinage. The figure's details are worn but still discernible.

The reverse side (right) seems to depict a standing figure, possibly holding an object, though the corrosion has obscured much of the design. The bottom portion of this side has significant green patina, making further identification of details difficult. The coin overall reflects signs of age and wear, suggesting historical significance.
