If we want to say that the copper dollar minted in China's history is the largest and the face is also the largest copper dollar, then it is definitely the five-hundred-text double flag coin minted by the Henan Mint at that time.
How big is the diameter of this five-hundred-dollar piece? The diameter of 45 mm, larger than the Daguan FoldIng Ten Ancient Coins we saw, the weight is 33.7 grams, we generally say that Yuan Datou's weight is only about 26.8 grams, it can be seen that this copper dollar has completely exceeded the silver dollar of Yuan Datou in terms of size and weight.
Of course, the five hundred and five sample coins are not officially circulated in the market, it is also the existence of a trial minted sample coin, its price is also very high, reaching more than six figures, speaking of which I have to mention that it is precisely because the Henan Mint has minted a large number of copper dollars of this large denomination.
And I said two hundred texts before is an example, which directly led to the final Henan Mint because copper can not be obtained, and finally forced to close, I hope you can learn more about some of the relevant ancient coin knowledge, if you have different views, welcome to leave a message in the comment area to share.
