What was the mother money like in Qing Dynasty?

In the mid-Qing dynasty, the basic characteristics of mother money were representative. The copper of mother money was fine and delicate, and there were few sand holes on the surface of money. The purpose of this is to make the inner surface of the manufactured coin mold smoother.

In the middle of Qing Dynasty, the outer edges of some mother coins were trimmed to be the same as the back of carp, commonly known as "fish back". The advantage of this is that it is more conducive to the demoulding of coins when casting.

The mother money changed slightly in the middle and late Qing Dynasty. Most of the money meat of Xiaoping's mother money is curved, and the low-money meat of the root and the inner root is high. Due to the rise of copper price in Xianfeng period, large denomination coins were produced. With the increase of money types, the convex surface of money meat gradually flattened. Due to the variety and size of money, the gap is obvious, and the casting technology of coins has changed accordingly, and the style of mother money is different from that of Ganjiadao period.
