I wonder what ruler, and age, this Chinese cash coin is. I have no idea of how to write in Chinese, and I truly know just one word of it, which is why I posted this on here. For those of you who know Chinese, can you help me attribute this?
I wish I could. I saw a man once in my Son's Karate class that had a whole big box of these coins. I wondered? Why the holes and why square?
I highly recommend the site @Inspector43 linked to. https://en.numista.com/catalogue/pieces19755.html
You need to turn it 90 degrees counterclockwise. I think it's the 1736-1795 coin, which is the most common date I see. The only symbols I really look at to identify are the top and bottom.
According to my old Krause catalogue, it is Emperor Ch'ien-lung, 1736-1795. As Hidden dragon said, turn it counterclockwise 90 degrees. The reverse identifies the mint as the Board of Public Works, Beijing.
