As a sample coin of early trial engraving, the casting quantity of Yuan Datou with seven faces is very small, which is even rarer in the world. This kind of coin belongs to the treasures of silver coins, which are divided into two types: the signature version is a second-class treasure, and the ordinary version is also a fourth-class treasure.
