What kind of silver is Wen Yin?

It is equivalent to pure silver now, and generally refers to silver with complete fineness.

Before the Ming Dynasty, silver was not used as currency, but was mostly used to make exquisite utensils, such as silver bowls and silver chopsticks, which was a symbol of status. After the Wanli period of the Ming Dynasty, a large number of silver from Europe and America entered China.

The annual revenue of the imperial court reached more than two million yuan, and some people began to pay bills with silver. For example, when they go to a restaurant, they can pay with silver after dinner. In the Qing Dynasty, the use of silver as currency became more popular, and many people no longer carried copper coins with them, but changed to silver.
