Kangxi Tongbao, with a diameter of 28 mm and a thickness of less than one millimeter, why is it so t

According to the title, Kangxi Tongbao has a diameter of 28 millimeters and a thickness of less than one millimeter, so it can be inferred that its thickness is very thin.

To explain why Kangxi Tongbao is so thin, we need to consider its historical background and manufacturing process.

First of all, Kangxi Tongbao is a copper coin minted during the Kangxi reign of the Qing Dynasty (1662-1722). Under the monetary system at that time, copper coins were one of the main currencies in circulation, and Kangxi Tongbao was one of the more common copper coins.

Secondly, the manufacturing process of copper coins mainly includes two steps: casting, molding, processing and grinding. In the casting molding stage, copper coins are usually made by melting copper and pouring it into a mold to cool. In this process, the thickness of the copper coin is usually affected by the thickness of the mold.

If the thickness of the mold is insufficient or the temperature of the molten copper is too high, the thickness of the copper coin will be too thin.

In addition, during the processing and grinding stage, the copper coin may be thinned or worn out, which is also one of the reasons for the insufficient thickness of the copper coin.

To sum up, the reason why Kangxi Tongbao is so thin may be due to some factors in the two processes of casting and processing and grinding.

It may be that the wear and tear of circulation at that time was more severe, so it was thinner. It's true. The market price is about 10 yuan.

There is no doubt about the genuine product, but it is a pity that it is badly worn, so it is so thin.
