When did the five-baht coin officially appear? This we want to talk about the fourth currency reform of Emperor Wu of Han, the fourth currency reform of Emperor Wu of Han was in the fifth year of the Yuan Hunt, which was also the second year of Wei Qinghuo's northern expedition to the Xiongnu, and this currency reform of five baht money is exactly the emergence.
Because at that time, the central government had already delegated the right to mint money to each county, so the minted five baht coins we commonly known as the county five baht, friends who play coins know that the five baht of the county state is actually more obvious, that is, the size, thickness are uneven and inconsistent, because the standards before the minting of each county are not the same.
The central government instructed them to give them a unified standard for casting five baht for the county state, but it is another matter if this is not implemented according to this standard, so it is said that the five baht of the county state that we see now can reach six or seven grams in weight, and three or four grams in the light, which is the emergence of the five baht of the county state, that is, a form of the earliest appearance of five baht money.
After the appearance of the five-baht coin, the half-two coins gradually withdrew from the historical stage, because Emperor Wudi of Han had abolished the four-baht and half-two coins, so that from the beginning of King Zhaoxiang of Qin zhaoxiang to the fifth reform of Emperor Wudi of Han, the mission of half two dollars was over.
