明太祖朱元璋于洪武元年（公元1368年）命京城（南京）工部宝源局及各省宝泉局铸行“洪武通宝”，由工部主管铸钱，下设宝源局。《明史·食货志》曰：“（戊申、太祖）即位，颁洪武通宝钱，其制五等：当十、当五、当三、当二、当一。当十钱重一两，余递降至一钱止。”钱文真书，直读。当十大钱一般径4.6厘米，重34.4～37克；当一径2.45厘米，重3.4～3.6克。据湖南常德中国收藏家协会会员周新国先生的“武陵藏珍”考证：吴二年（1368年）正月，朱元璋称帝，建立明朝，改元洪武；同年三月，开铸“洪武通宝”钱，仍继大中钱式，行五等钱。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，明太祖朱元璋于洪武元年（公元1368年），命京城（南京）工部宝源局及各省宝泉局铸行“洪武通宝”，由工部主管铸钱，下设宝源局。朱元璋为避讳元朝的元字，把所铸之钱钱文一律叫通宝而不叫元宝，而不只是为避讳他自己的名字，以后所铸之钱也都没有元宝钱文。洪武通宝钱制沿续元末朱元璋所铸“大中通宝”的形制，分为五等，规定小平钱，每文重一钱，折二钱重二钱，当三钱重三钱，当五钱重五钱，当十钱重一两。同时继铸大中通宝钱。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.
母钱是古时翻铸大量钱币时，中央和地方财政所制作的标准样板钱。母钱作为样板的用途，可分为三种，即钱样、雕母钱和铸母钱。
钱样是根据钱币的设计，用锡、象牙或红木等材料精心雕制的钱币实物样板，它的用途是呈送朝廷，供皇帝审定。从严格意义上讲，钱样还不能算作钱币，因为它只作为送审报批的实物图样，不能流通。因此及其稀少，千金难求
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.
近年来钱币收藏者和投资者越来越多，业内人士表示洪武通宝母钱在未来的瓷器市场中极有可能成为收藏投资领域里的一匹“黑马”。一则印章作为曾经的名人收藏作品，反映了当时的政治、金融与文化背景、历史价值不菲。加上交易比较灵活、投资风险小、增值稳定等特点，以及材质珍贵，艺术价值高，制作精美，图案考究，文字清秀，内容丰富，具有一定的保值和升值功能，故收藏价值很大。
In recent years, there are more and more coin collectors and investors. Insiders say that Hongwu Tongbao's mother money is likely to become a "black horse" in the field of collection and investment in the future porcelain market. A seal, as a collection of famous people's works, reflects the political, financial and cultural background and historical value at that time. In addition, the transaction is relatively flexible, the investment risk is small, the value-added is stable, and the material is precious, the artistic value is high, the production is exquisite, the pattern is exquisite, the writing is beautiful, the content is rich, and has a certain value preservation and appreciation function, so the collection value is great.
