The image depicts two sides of a heavily corroded coin. The coin appears to be made of bronze or a similar metal, evidenced by the green patina (likely due to oxidation) covering large portions of its surface. The corrosion and wear make it difficult to discern any details or inscriptions, but faint traces of shapes or designs suggest it may have had a portrait or symbols at some point. There is a scale to the right of the image, denoted in centimeters, providing a reference for the size of the coin. The background is solid black, emphasizing the texture and condition of the coin.

This image shows an ancient bronze coin, depicted in two photos side by side, showing its obverse (left) and reverse (right) sides. The coin appears heavily worn and corroded, with a rough and uneven surface, possibly showing areas of green patina indicative of copper oxidation. The design on the coin is not clear due to extensive wear, but on the left side image (obverse), there seems to be a faint outline of a head or bust, although details are obscured. The right side image (reverse) is more eroded and does not show any distinguishable design features. The scale to the right with centimeter markings indicates the coin's size, which seems to be small, as coins typically are. Without more information or clearer imagery, the coin's origin or period is difficult to determine.

Created by Qwen/Qwen2.5-VL-7B-Instruct on 2025-07-13

The image shows two ancient coins side by side against a dark background. Both coins appear to be corroded and have a greenish patina, which suggests they are made of copper alloy, possibly bronze, and have been exposed to moisture and air for a long time, leading to this oxidation. The coin on the left appears to have a circular design with some visible wear and tear, while the coin on the right is more worn, with a rough and uneven surface. The surface of both coins has patches of green corrosion, indicating oxidation, and some areas that are darker, possibly due to further deterioration or different material composition. On the far right side of the image, there is a vertical scale indicating centimeters, which helps in assessing the size of the coins.

  • Obverse (left): The coin appears heavily corroded with greenish and brownish patches, indicating oxidation over time. The design is mostly obscured by the corrosion, but there seems to be a central figure, possibly a human face or head, surrounded by other indistinct elements.
