Comment

These are attributed to the State of Qi, and are largely found in the Shandong area. While the characters on the obverse are constant, those on the reverse have a lot of variations.

Interesting fact

One interesting fact about the Qi knife coin is that it was used as a form of currency during the Warring States period in ancient China, and it was also used as a weapon for self-defense. The coin's design features a knife-like shape, which gave it its name "Qi knife." The coin's unique design and dual purpose make it a fascinating piece of history.
