The image shows two ancient bronze coins displayed against a black background. Each coin features a patina of green and brown hues, indicative of its age and the materials used in its production. The coins are circular in shape and have a diameter that appears to be approximately 2-3 centimeters, as suggested by the ruler on the right side of the image.
