This appears to be an ancient bronze or copper coin with a green patina, which is typical of aged copper-based metals. The coin shows signs of significant age and wear, with a portrait in profile visible on its surface. The green coloration is due to oxidation over time, creating what's known as a verdigris patina. The image includes a measurement scale on the right side in centimeters, suggesting this is likely a photograph taken for archaeological or historical documentation purposes. The coin appears to be photographed against a black background, which helps highlight its details and texture. Based on its style and appearance, it could be a Roman or similar ancient currency, though without clearer details of the markings and text it would be difficult to specify its exact origin.

Here is a description of the image:

The image shows two ancient bronze coins, side by side, set against a black background with a vertical centimeter ruler to the right. The coins are circular, though with a somewhat irregular shape, possibly due to wear or damage. Both coins are a dull, greenish-brown color, indicative of oxidation and age.

The coin on the left appears to be the obverse of a coin. It features a portrait of a person in profile. The person has a flowing hairstyle and a decorated head. Surrounding the portrait is an inscription which is difficult to fully read due to the condition of the coin, but it likely names a ruler or figure. A large "bite" is taken from the top of the coin.

The coin on the right presents the reverse of a coin. It depicts a scene or design, possibly a figure on horseback or a similar emblematic image. Here too, the details are worn, but traces of lettering are still visible. Again, a "bite" is taken from the top.

The overall impression is of old coins, likely Roman or similar, that have been subject to wear and tear, and have been damaged over time.
