Which is better, coins or antique copper coins?

Personally, I think hexagrams have little to do with the props used. Actually, coins may be better. This consideration is based on my acceptance of the following theoretical viewpoints:

There are different opinions on the principle of divination in modern times, and individuals tend to interpret it with Jungian psychology, that is, "collective unconsciousness" and "simultaneity principle" This set of principles can accommodate the principles explained in Zhouyi and Meihua Yishu. All your actions (including divination) actually reflect the holographic nature of the field, which is not something like electricity and electromagnetic waves detected by modern science. So it has nothing to do with the material in essence.

The fire bead forest method initiated by Taoist Gumabu and others should use the currency copper coins circulating in the market at that time, rather than any special collection of copper coins. This is because the common currency circulates around the world, which is both expensive and cheap. It is an ownerless thing, which does not distinguish between good and evil, loyalty and traitors, rich and poor, men and women, old and young, and is more in line with what Laozi and Zhuangzi said. Therefore, the most popular coins in the world are like the law! ? If collectibles and special currencies are used, there will be no bearing of the above meaning, so it will not work.
