I have a coin with a circle on the front and a warrior with a spear and shield on the back.

Zhanyang, 1895 As Britain restricted the outflow of local silver coins, the British government minted new trade silver coins in Mumbai and Kolkata, India, for British trade in Asia. So strictly speaking, it still belongs to British silver coins, and the standard name is "British Trade Silver Dollar". In the center of the front of the silver dollar is an English goddess holding a halberd shield (so it is commonly known as "standing in the ocean" or "standing up" in our country). There is an English currency "ONE DOLLAR" (one yuan) around the upper end of the goddess, and there is a date; The center of the back is Shou Ziwen, with Chinese "one circle" from top to bottom and Malay "one circle" from left to right. The weight is 26.9568g, and the color is 90.0%. After the issuance, this currency has been widely circulated in Asian countries, especially in East Asia and Southeast Asia. After entering China, it first spread in Guangdong and Guangxi. 1900 began to be used in the north, especially in Beijing and Tianjin, which occupied more than half of China from south to north. At that time, Hong Kong had not issued a one-dollar silver coin, which was once qualified for legal circulation in Hong Kong, so some areas in Guangdong used to call it "Hong Kong dollar" or "the light of Hong Kong".
