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，同时继铸大中通宝钱。洪武八年，发行“大明宝钞”纸币，规定大明宝钞每贯合铜钱一千文或值银一两，宝钞四贯合黄金一两。并且实行铜钱与宝钞并用的政策，但禁止金银流通，只能向政府兑换。
In the early Ming Dynasty, Ming Taizu Zhu Yuanzhang Yu Hongwu (1368 AD), the first year of life capital (Nanjing) industry Schroder Bureau and provincial Baoquan Bureau cast "Hongwu reign", by the supervisor cast money under the Schroder bureau. Zhu Yuanzhang Yuan Yuan taboo words, to cast paper money are called Tongbao instead of gold, not just shy of his own name, after the cast money are not gold paper money. Hongwu reign continued for money at the end of the yuan Zhu Yuanzhang cast "big Tong Bao" shape, while following the cast big money man. Hongwu eight years, the issuance of "Da treasure" notes, each with Guan Da treasure provisions of article one thousand or one or two silver coins, four gold and one or two Po guan. And the implementation of the policy and the coins and notes, but no gold and silver in circulation, only to the government exchange.
这枚钱币从以下几个特点突出价值：
This coin has a prominent value from the following features:
1、以铸造年代：明朝为推行纸币的流通，当年就停止了中央及各地方钱局的铸钱。到第二年全部停铸铜钱。明朝洪武十年，又恢复宝源局与各省钱局铸小钱至洪武二十年后又停铸。洪武二十六年，改变钱制，重新铸五等钱，其它四等钱，依照小平钱之重递增。洪武二十六年七月只准京师宝源局铸钱，其它各省再次停铸。到八月，因宝钞流通受阻，为坚决实行纸币制度再次禁止使用铜钱。直到明宣宗宣德末年，历时长达四十一年。
1, by casting the age: the Ming Dynasty for the implementation of the circulation of paper money, then stopped the central and local money Bureau of the cast. To second years all the cast coins. Ming Hongwu ten years, again Schroder Bureau and each cast money to save money Bureau Hongwu twenty years after stopping casting. Hong Wu twenty-six years, change the money system, re cast five and other money, the other four and other money, according to the weight of the Xiaoping money. Hongwu twenty-six years July only capital Schroder Bureau cast money, other provinces once again to stop casting. By August, the circulation is blocked because of Po, and resolutely implement the system of paper currency again banned the use of coins. Until the Ming emperor Xuande Dynasty, which lasted for more than forty-one years.
2、以铸造工艺及铸币材质:背面字体干净利落，洪武有力，不拖泥带水。包浆浑厚自然，历史痕迹明显。
2, the casting process and mint material: back font Hongwu strong, smooth and clean, not sloppy. Patina rich natural history traces。
3、此钱计有背京（应天）、北平（府为北平府，二年，北平行中书省）、鄂（湖北省）、浙（浙江省）、济（山东省）、桂（广西省）、福（福建省）、豫（河南省）、广（广东省）等九种，各有小平、折二、当三、当五、当十五等。其中，背桂小平钱有穿上桂和穿上下“桂一”两种，实共四十六种。小平钱至当五四等钱的记局名大多铸于穿上，仅背福、豫者字在穿下，背广者字在穿右。照史书的记载，福建到永乐年间才铸钱，湖广到弘治年间才铸钱，可是洪武钱中，却有“福”字和“鄂”字。这是有待研究澄清的问题。在这些背文中，“京”“济”“鄂”等字都少见。
3, the money is back (Ying Tian) Beijing, Beijing (Palace mansion in Beiping, two years, the North parallel Zhongshusheng (Hubei province), Hubei, Zhejiang) (Zhejiang province), Ji (Shandong province) and Guangxi (Guangxi province), Fu (Fujian province), Henan (Henan province), Canton (Guangdong province) nine, each have two fold, when Xiaoping, three, when five, when fifteen etc.. Among them, there are two kinds of the money in the back of GUI Xiaoping, put on the GUI and put up and down, "Gui one", a total of forty-six kinds. Xiaoping put 54 money money board are cast in the wear, only back Fu, Henan who wear the word in the back, wide in wearing the right words. According to historical records, Fujian Yongle was cast to cast money into money, Huguang Hongzhi, but Hong Wu money, but the word "happiness" and "e". This is a question to be clarified. In these back in the text, Beijing, "Ji" "e" and other words are rare.
