Chinese Republic Era Coin (Likely Sun Yat-sen or Chiang Kai-shek Portrait)

The item is a round metal coin, likely silver or a silver-colored alloy, based on its light grey, somewhat reflective appearance. The obverse prominently features a relief portrait of a male figure, depicted in profile facing left. The figure has a distinctive bald head and appears to be wearing a high-collared garment. Surrounding the portrait, along the rim of the coin, there are Chinese characters, suggesting its origin. The characters are somewhat obscured by what appears to be minor wear or a slight blur in the image, but they are clearly present and form a circular inscription. The surface overall shows a moderate degree of wear consistent with circulation, exhibiting a softened patina rather than a bright, uncirculated luster. There are no obvious deep scratches, dents, or significant damage, but the overall crispness of the details is somewhat diminished. The edges of the coin appear reeded, although this is not perfectly clear from the image. Given the portrait style and the presence of Chinese characters, this coin is likely from the early to mid-20th century, possibly a Republic of China era coin featuring Sun Yat-sen or Chiang Kai-shek. The craftsmanship appears to be of standard mint quality for its probable period, with a clear, though worn, strike. No visible maker's marks or specific minting details are discernible from the provided image.
