This image shows both sides of an ancient or medieval coin, likely made of bronze or copper, displayed against a black background. The coin is heavily worn and corroded, making the details of the design difficult to discern. However, faint designs can be seen:

  • On the left side, the pattern appears to show a vertical central figure or symbol surrounded by faint curved lines, possibly indicating a person, symbol, or architectural motif.
  • On the right side, faint outlines of what seems to be two standing human figures, adorned with possibly robes or armor, are visible. Additionally, there seems to be decorative elements in the background or surrounding the figures.

A metric scale is located on the right edge of the image, providing a sense of the coin's size for reference.

The image shows two ancient bronze coins with worn surfaces, indicating age and use. The coin on the left appears to have an image of a seated figure, possibly a ruler or deity, surrounded by a decorative motif. The details are not entirely clear due to the corrosion and wear on the coin.

The coin on the right seems to depict standing figures, possibly in a religious or ceremonial context. Like the other coin, the imagery is somewhat obscured by the condition of the bronze, but it appears to have multiple figures, perhaps indicating an important historical or cultural scene.

Both coins have an irregular shape typical of ancient minting practices. The background is a solid black, providing contrast to highlight the coins. There is a scale on the right side of the image marked with centimeters, indicating the size and physical measurements of the coins, suggesting they are relatively small objects.

The image showcases two ancient-looking, corroded coins against a black background. Both coins appear to be made of a copper-like metal, tarnished with age and possibly some light blue-green verdigris. The edges of the coins are irregular, suggesting wear, damage, or the original crude casting.
