First: wear, second: outer Guo, and third: inner Guo.

penetrate

Full penetration: If there is no perforation in the middle of the coin, we call it "full penetration", which is caused by improper operation when casting the mold.
Perforation: The perforation dislocation is not square, which is called "perforation", among which hexagonal perforation is called "tortoise shell perforation" and octagonal perforation is called "diamond perforation".
Then let's talk about foreign countries: the outermost circle of ancient coins, which we call "border country" or "foreign country"
