The image shows three rectangular plaques with Chinese characters on them. The plaques are mounted on a beige wall and have a white background. The text on the plaques reads "Cast Copper Coins of the Qing Dynasty" in both English and Chinese. Below the text, there is a description of the cast copper coins, which are known for their intricate designs and patterns.

The first plaques on the left side of the image show a set of four black coins, each with a unique design. The coins appear to be made of copper and have Chinese characters written on them, which likely provide information about the coins. The second plaques in the middle show the same type of coin, but with a different design and pattern. The third plaques at the bottom show a larger version of the coin, which appears to be a Chinese coin with a circular shape and a small hole in the center.
