明太祖朱元璋於洪武元年（公元1368年）命京城（南京）工部寶源局及各省寶泉局鑄行“洪武通寶”，由工部主管鑄錢，下設寶源局。《明史·食貨志》曰：“（戊申、太祖）即位，頒洪武通寶錢，其制五等：當十、當五、當三、當二、當一。當十錢重一兩，餘遞降至一錢止。”錢文真書，直讀。當十大錢一般徑4.6釐米，重34.4～37克；當一徑2.45釐米，重3.4～3.6克。據湖南常德中國收藏家協會會員周新國先生的“武陵藏珍”考證：吳二年（1368年）正月，朱元璋稱帝，建立明朝，改元洪武；同年三月，開鑄“洪武通寶”錢，仍繼大中錢式，行五等錢。In the first year of Hongwu (1368 AD), Zhu Yuanzhang, the emperor of Ming Dynasty, ordered Baoyuan Bureau of the Ministry of industry of the capital (Nanjing) and Baoquan Bureau of all provinces to cast "Hongwu Tongbao". The Ministry of industry was in charge of casting money, and Baoyuan Bureau was set up under it. The annals of food and goods in the history of the Ming Dynasty said: "when (Wushen, Taizu) ascended the throne, he issued Hongwu Tongbao money, with five systems: Dang ten, Dang five, Dang three, Dang two, Dang one. When ten dollars weigh one or two, the balance is reduced to one. " Qian Wen is a real book. Read it directly. When ten big coins are 4.6cm in diameter, they weigh 34.4-37g; when one is 2.45cm in diameter, they weigh 3.4-3.6g. According to Mr. Zhou Xinguo, a member of Hunan Changde Chinese collectors association, the research of "Wuling Treasure Collection": in the first month of the second year of Wu (1368), Zhu Yuanzhang became the emperor, established the Ming Dynasty, and changed the yuan to Hongwu; in March of the same year, the "Hongwu Tongbao" money was cast, still following the large and medium-sized money style and the fifth class money.明代初期，明太祖朱元璋於洪武元年（公元1368年），命京城（南京）工部寶源局及各省寶泉局鑄行“洪武通寶”，由工部主管鑄錢，下設寶源局。朱元璋為避諱元朝的元字，把所鑄之錢錢文一律叫通寶而不叫元寶，而不只是為避諱他自己的名字，以後所鑄之錢也都沒有元寶錢文。洪武通寶錢制沿續元末朱元璋所鑄“大中通寶”的形制，分為五等，規定小平錢，每文重一錢，折二錢重二錢，當三錢重三錢，當五錢重五錢，當十錢重一兩。同時繼鑄大中通寶錢。In the early Ming Dynasty, Zhu Yuanzhang, the founder of the Ming Dynasty, ordered Baoyuan Bureau of the Ministry of industry of the capital (Nanjing) and Baoquan Bureau of all provinces to cast "Hongwu Tongbao" in the first year of Hongwu (1368 A.D.), and the Ministry of industry was in charge of casting money, under which Baoyuan Bureau was set up. In order to avoid the yuan characters of the Yuan Dynasty, Zhu Yuanzhang called all the money and articles cast as Tongbao instead of Yuanbao, not only to avoid his own name, but also no money and articles cast in the future. Hongwu Tongbao money system is based on the shape of "Dazhong Tongbao" cast by Zhu Yuanzhang at the end of the successive Yuan Dynasty, which is divided into five grades. It is stipulated that Xiaoping money is one yuan for each article, two yuan for each article, three yuan for three, five yuan for five, and ten yuan for one or two. At the same time, it continued to cast Dazhong Tongbao money.
母錢是古時翻鑄大量錢幣時，中央和地方財政所製作的標準樣板錢。母錢作為樣板的用途，可分為三種，即錢樣、雕母錢和鑄母錢。
錢樣是根據錢幣的設計，用錫、象牙或紅木等材料精心雕制的錢幣實物樣板，它的用途是呈送朝廷，供皇帝審定。從嚴格意義上講，錢樣還不能算作錢幣，因為它只作為送審報批的實物圖樣，不能流通。因此及其稀少，千金難求
Mother money is the standard model money made by central and local finance when a large number of coins were converted in ancient times. The use of mother money as a model can be divided into three types: money sample, sculptor money and casting mother money.
According to the design of coins, the coin samples are carefully carved with tin, ivory or mahogany. Their purpose is to present them to the imperial court for examination and approval. In a strict sense, the money sample can not be counted as money, because it is only used as a physical pattern for examination and approval, and cannot be circulated. Therefore, it is very rare and hard to find a thousand gold.
