Edition, Mingdao Yuanbao Zheqian, Tianxi Qiaoweitong, Jingde Yuanbao Sibiyuan, Jingyou Yuanbao Caoyuan, etc., etc., there are many, and the fonts are all involved, running script, cursive script, seal script, official script, etc.

I also told him the methods for detecting counterfeiting of coins, including changes in engraving, sand casting, digging out characters, and new casting of old copper.

The skinny boy was only fifteen years old at that time. A few years later, he did an amazing thing in Beijing. Even Meimei of Yongzhou Meiqian Hall heard about the boy's name "Huanglongkou".

I didn't take it seriously at first. Those sold to little devils were very cheap.

At that time, the concept of Song Dynasty mother coins and individual Song Dynasty trial coins was very weak, and even many merchants did not have this concept. The little devil bought a lot of them for thirty or fifty yuan a piece.

The thin boy felt that this was something unusual. He was the quickest to figure out the concept of "Song Yuan's Mother".
