Extended data:
There are two sources of money in ancient times: one is handed down from generation to generation. The closer this ancient money is to the present age, the more it is handed down, and the rarer it is. The other one was unearthed. Many people think that ancient money was unearthed from tombs, but it is not. Most of the ancient money we see today comes from cellar storage, which refers to the storage and custody of property in the cellar. Only a tiny part comes from the grave. There are two reasons:
1. There were no banks in ancient times. The way people store coins is to put them in containers and bury them underground or other private places. Especially during the war and famine, people fled and were buried because of the inconvenience of carrying coins.
2. In ancient China, there were few customs of using coins as funerary objects. Emperors of past dynasties may not form the custom of using coins as funerary objects. So far, we can see from the tombs that have been discovered that most of the funerary objects in ancient tombs in China are gold and silver, jewelry, porcelain, jade, textiles and so on, while ancient coins are very few.
