On the left side, the obverse (front) of the coin is visible. It is heavily worn and corroded, with faint details resembling a profile of a figure or face, surrounded by a circular outline. The surface shows brown and green patina from oxidation.

On the right side, the reverse (back) is shown. It features more distinct circular patterns, with markings possibly including symbols or letters; one of them resembles a triangular or delta-shaped figure. The coin exhibits a similar green patina as the front but appears better preserved in terms of recognizable details.

The image shows two views of an old, weathered coin, likely made of bronze or a similar metal. They are set against a black background, with a centimeter scale on the right side of the frame.

The coin is circular, but its edges are irregular due to wear and corrosion. The left view shows a heavily degraded face, with very little of the original design visible. There are some raised areas, but they are difficult to distinguish and interpret due to the coin's condition.

The right view of the coin is slightly better preserved. It features a design of some kind, possibly Greek letters or symbols. The most prominent is a symbol that looks like a triangle, possibly a delta, positioned in the center of the coin. There are also what appear to be two vertical lines with small circles beneath. The design is surrounded by a circular border.

Both sides of the coin show significant signs of age and wear, including pitting, corrosion, and discoloration. The metal has taken on a greenish-brown patina, which is common for ancient bronze artifacts.
