Here's a description of the image:

The image shows two ancient, likely Roman, coins against a stark black background. A centimeter ruler is placed to the right, providing a sense of scale. Both coins appear to be made of bronze or a similar metal, exhibiting signs of age, including corrosion and a patina of green.

  • Coin 2 (Right): The second coin has a slightly more irregular shape. On one side, there is a depiction of a figure sitting, perhaps a deity or emperor, holding an item and is seated in front of what looks like a structure. The style of the figure suggests a Roman origin. The details are more well preserved. There is a green patina present here as well.
