Mexican silver dollar, also known as "Mexican silver" or "Eagle Ocean", was later mistaken for "British Ocean". Refers to the new coinage 182 1 used after Mexico's independence. Cast in 1823.
There are two kinds of eagle ocean: lace eagle ocean before 1897 and straight eagle ocean after 1898. During the late Qing Dynasty and the Republic of China, the largest number of foreign silver dollars were imported into China. According to the statistics of Xuan Tong Branch in the second year of Qing Dynasty, there were about 1 1 billion foreign silver dollars circulating in China at that time, and one third of them were Mexican eagle coins, which had high collection value.
Historical origin:
The color of Mexican eagle ocean is better than other foreign silver dollars, which has remained unchanged for many years and people are happy to use it. Mexican Eagle Ocean is widely circulated in the southern and central provinces of China, and almost becomes the main currency. Foreign banks in Shanghai used Mexican Eagle Ocean as the exchange standard when issuing paper money before the Republic of China.
The United States once minted a trade silver dollar, with a goddess sitting on the front with a flower in her hand and an eagle on the back. The United States wants to use the trade silver dollar to compete for the status of Mexico's eagle ocean. But because the quality of American trade silver dollar is not high, it finally failed.
