Why are ticks in Ping Zi?

The reason is that I bought this Xianping gold ingot last year. There is a tick in the word Ping Zi, which was bought as an interesting product of copper flow. A friend who posted it pointed out that this is a fixed version called Gou Ping. So I paid attention to this version of Gou Ping. The mainstream view on the Internet is that this version does exist, and a large number of discoveries have been recognized by many people.

In addition, some people think that it is the fixed wear caused by the long-term use of the money mold.

I don't know if there is a way to write flat characters with hooks in calligraphy, but I feel that it is not written like this. I have also considered private casting, side furnace, Annan and so on, but the overall feeling of looking at money is not like these three categories.

Because this edition of "Northern Song Dynasty Copper Coin" is not in the spectrum, it seems that this edition is not in other visible Song spectrum, so there are still some questions.

Generally speaking, it is rarely recognized that there are spectral products, but after a certain period of attention, this version does have many physical drawings. It should be a version, right Song Hui members, what do you think?
