Japanese coin/token

The image shows an ancient, round metal coin with a square hole in the center. The surface of the coin appears weathered and tarnished, bearing an intricate, yet faint, design along its circumference. This design seems to contain a series of symbols or characters that, while partially eroded, suggest historical or cultural significance. The coin’s metal, likely bronze or a similar alloy, displays a patina indicating age, adding a sense of history and antiquity. Near the edge, numbers are inscribed, potentially reference or catalog numbers, which may have been added for identification in a collection or a museum setting. The overall appearance of the coin, including its condition and markings, speaks to a storied past, perhaps part of a larger archaeological find or numismatic collection. The central square hole is a defining feature, characteristic of certain ancient currencies, possibly from East Asia, which often feature such designs for easy transport on a string.
