1368年朱元璋建立明朝之后，改元洪武，铸行“洪武通宝”，“大中”钱遂即停造。图中“大中通宝”币身略薄。币有穿部，内外部均匀，正面书有“大中通宝”四字，布局疏朗，“通”字为单通。大中钱分五种，有小平、折二、折三、折五和折十，且除宝源、宝泉两局外，朱元璋还陆续发行带有地名的货币，如鄂、京、浙、广等简称，铸于铜币背面，因之形成了多种等级的大中铜币系列。
In 1368, after Zhu Yuanzhang established the Ming Dynasty, the Yuan Dynasty Hongwu was changed, and the "Hongwu Tongbao" was cast. The "Dazhong" money then stopped making. The "Dazhong Tong Bao" coin in the picture is slightly thinner. The coin has a wear department, inside and outside uniform, the front book has "big and middle tong bao" four words, the layout is clear, "pass" word for the single pass. A character of ten was cast across the back of the coin. Large and middle money is divided into five kinds, including Xiaoping, fold two, fold three, fold five and fold ten. In addition to Baoyuan and Baoquan, Zhu Yuanzhang also successively issued currencies with place names, such as E, Beijing, Zhejiang, Guangzhou and other abbreviation, which were cast on the back of copper coins, thus forming a series of large and middle copper coins of various grades.
朱元璋在浙西驻扎6年，借助覆船山为中心的秘密明教总舵，奉行徽州谋士朱升提出的“高筑墙，广积粮，缓称王”的策略，迅速秘密扩张自己的实力，这三条战略是朱元璋发展初期的指导思想。但由于红巾军内部分裂，陈友谅、张士诚等人作乱，从1360年到1366年，朱元璋外对元军，内应陈、张二人，内忧外患，战争年延不断。最终，朱元璋吞并了陈友谅，通过发动平将战意，铲除了张士诚。就在朱元璋在军事上有了一席之地后，也就是公元1361年，他在应天府（今南京）铸造了“大中通宝”。
Zhu yuanzhang stationed in western zhejiang for 6 years, with the help of the secret master of the Ming religion at the center of feichuan mountain, followed the strategy of "building a wall high, accumulating grain widely, and becoming the king slowly" proposed by huizhou strategist zhu sheng, and rapidly and secretly expanded his own strength, these three strategies were the guiding ideology of zhu yuanzhang in his early development. However, due to the internal division of the Red Turban Army, Chen Youliang, Zhang Shicheng and other people caused chaos. From 1360 to 1366, Zhu Yuanzhang fought against the Yuan Army outside of Chen and Zhang, causing internal troubles and foreign invasion. The war continued for years. Eventually, Zhu Yuanzhang swallowed up Chen Youliang and removed Zhang Shicheng by launching a campaign of peaceful generals. After Zhu Yuanzhang had established himself as a military leader, in 1361 AD, he forged the "Great Zhongtong Bao" at Yingtian Fu (now Nanjing).
“大中通宝”就是朱元璋与元军和陈友谅、张士诚三撮势力的斗争中铸造的货币，是元末反元斗争的产物。由于元末社会动乱，纸币支持的经济体系遭到了严重破坏，元境内各地先后恢复了铜钱的流通。几支反元军事集团先后发行了自己的铜币，如韩林儿的“龙凤通宝”钱，陈友谅的“大义通宝”，张士诚的“天佑通宝”钱，明玉珍的“天统通宝”钱，以及朱元璋“大中通宝”钱。几支钱币中，唯有“大中通宝”取得成功。在战争期间，朱元璋是韩林儿的部下，他采用谋略，一方面协助韩林儿发行“龙凤通宝”，另一方面笼络民心，在战争期间答应老百姓继续使用元代交钞，规定交钞一两值作“龙凤通宝”四十文使用，十两交钞作一贯使用，作为补充。他还在应天府设置宝源局，开始铸造“大中通宝”，与其它货币一起参与流通。直到至元二十四年始大规模发行。1368年朱元璋建立明朝之后，改元洪武，铸行“洪武通宝”，“大中”钱遂即停造。
"Dazhong Tong Bao" is the currency forged in the struggle between Zhu Yuanzhang and Yuan Jun, Chen Youliang and Zhang Shicheng. It is the product of the struggle against Yuan Dynasty at the end of Yuan Dynasty. Due to the social turmoil at the end of the Yuan Dynasty, the economic system supported by paper money was seriously damaged, and the circulation of copper coins in various parts of the Yuan Dynasty was resumed successively. Several anti-Yuan military groups successively issued their own copper coins, such as Han Liner's "Long Feng Tong Bao" coins, Chen Youliang's "Dayi Tong Bao" coins, Zhang Shicheng's "Heavenly Bless Tong Bao" coins, Ming Yuzhen's "Tiantong Tong Bao" coins, and Zhu Yuanzhang's "Dazhong Tong Bao" coins. Among several coins, only "Dazhong Tong Bao" achieved success. During the war, zhu yuanzhang is Han Liner subordinates, he used counsel, assist Han Liner issue "longfeng TongBao" on one hand, on the other hand, otherwise, during the war to allow people to continue to use the yuan dynasty JiaoChao, stipulation JiaoChao two values for the use of "longfeng TongBao" forty articles, juryo JiaoChao consistent use, as a supplement. He also set up a Baoyuan Bureau in Yingtianfu and began to mint "Dazhong Tong Bao" to participate in circulation with other currencies. It did not begin to issue on a large scale until 24. In 1368, after Zhu Yuanzhang established the Ming Dynasty, the Yuan Dynasty Hongwu was changed, and the "Hongwu Tongbao" was cast. The "Dazhong" money then stopped making.
