明代初期，明太祖朱元璋于洪武元年，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(shè)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，以后所鑄之錢也都沒有元寶錢文。

洪武通寶錢制沿續(xù)元末朱元璋所鑄“大中通寶”的形制，分為五等，規(guī)定小平錢，每文重一錢，折二錢重二錢，當(dāng)三錢重三錢，當(dāng)五錢重五錢，當(dāng)十錢重一兩。同時(shí)繼鑄大中通寶錢。洪武八年，發(fā)行“大明寶鈔”紙幣，規(guī)定大明寶鈔每貫合銅錢一千文或值銀一兩，寶鈔四貫合黃金一兩。并且實(shí)行銅錢與寶鈔并用的政策，但禁止金銀流通，只能向政府兌換。

明朝為推行紙幣的流通，當(dāng)年就停止了中央及各地方錢局的鑄錢。到第二年全部停鑄銅錢。明朝洪武十年，又恢復(fù)寶源局與各省錢局鑄小錢至洪武二十年后又停鑄。洪武二十六年，改變錢制，重新鑄五等錢，按洪武元年鑄行規(guī)定，后又改銅錢每文重一錢兩分。其它四等錢，依照小平錢之重遞增。洪武二十六年七月只準(zhǔn)京師寶源局鑄錢，其它各省再次停鑄。到八月，因?qū)氣n流通受阻，為堅(jiān)決實(shí)行紙幣制度再次禁止使用銅錢。直到明宣宗宣德末年，歷時(shí)長(zhǎng)達(dá)四十一年。

明朝洪武年間，全國(guó)各省除少數(shù)省外，都沒有鑄錢爐，年鑄錢約十九萬貫，其中洪武五年時(shí)鑄錢最多。洪武《鑄錢則例》規(guī)定，鑄錢應(yīng)用生銅。但當(dāng)時(shí)銅材稀缺，所以就普遍用廢錢和舊銅鑄造，因銅質(zhì)復(fù)雜，純度不一，而造成“洪武通寶”成色不一的情況。

朱元璋建立明朝之后，將年代改為了洪武，所以對(duì)于新建鑄的貨幣稱作“洪武”。在其他年代的時(shí)候，會(huì)將錢文稱作元寶，但是在明朝的時(shí)候，當(dāng)朝者是朱元璋，因?yàn)橹煸暗拿掷锩嬗幸粋€(gè)“元”字，這就避諱了，所以在明朝的時(shí)候，無論多大多小的錢文都稱作了“通寶”。

此幣極其稀少 市場(chǎng)價(jià)值高 收藏品相也非常不錯(cuò)，輪廓清晰，背面的牧牛打造的栩栩如生，在錢幣類此錢幣不論品相還是價(jià)值都是非常值得收藏與投資。

In the early Ming Dynasty, Ming Taizu Zhu Yuanzhang, in the first year of Hongwu, ordered the Baoyuan Bureau of the Ministry of Industry of the Capital (Nanjing) and the Baoquan Bureaus of the provinces to cast the "Hongwu Tongbao". The Ministry of Industry was in charge of casting money and the Baoyuan Bureau was set up. In order to avoid the Yuan characters of the Yuan Dynasty, Zhu Yuanzhang called all the money coins he casts as Tongbao instead of Yuanbao, not just to avoid his own name, and there will be no ingot coins for the money cast in the future.

The Hongwu Tongbao money system follows the form of the “Dazhong Tongbao” cast by Zhu Yuanzhang at the end of the Yuan Dynasty. It is divided into five categories. It is stipulated that the small flat money shall be one coin per article, and the second coin shall be worth two coins. Money weighs five dollars, and ten dollars weighs one or two. At the same time, continue to cast Dazhong Tongbao money. In the eighth year of Hongwu, the "Daming Treasure Banknotes" banknotes were issued. It was stipulated that each of the Daming Treasure Banknotes was worth one thousand wen of copper coins or one or two silver, and that the four Treasure Banknotes were worth one or two gold. In addition, the policy of using copper coins and precious banknotes together is implemented, but the circulation of gold and silver is prohibited and only exchanged with the government.

In order to promote the circulation of banknotes in the Ming Dynasty, the central and local money bureaus stopped making money. By the second year, all copper coins will be stopped. In the tenth year of Hongwu in the Ming Dynasty, the Baoyuan Bureau and the provincial money bureaus resumed making small coins until Hongwu twenty years later, and then stopped. In the twenty-sixth year of Hongwu, the money system was changed and the fifth-class coin was recast. According to the regulations of the foundry in the first year of Hongwu, the copper coin was changed to weigh one coin and two cents later. The other fourth-class money is increased according to the weight of Xiaoping's money. In July of Hongwu 26, only the Baoyuan Bureau of the capital was allowed to make money, and other provinces again stopped making money. In August, the use of copper coins was once again banned in order to resolutely implement the paper currency system because the circulation of treasure notes was blocked. It lasted forty-one years until the last year of Xuanzong Xuande of the Ming Dynasty.

During the Hongwu period of the Ming Dynasty, all provinces in the country, except for a few provinces, did not have a coin-making furnace, and the annual coin was about 190,000 Guans. Among them, Hongwu made the most money in five years. Hongwu's "Rules for Casting Money" stipulates that copper should be used for casting money. But copper was scarce at that time, so waste money and old copper were generally used for casting. Because of the complexity of copper and the varying purity, the quality of the "Hongwu Tongbao" was different.

After Zhu Yuanzhang established the Ming Dynasty, he changed the year to Hongwu, so he called the newly minted currency "Hongwu". In other eras, Qian Wen was called Yuanbao, but in the Ming Dynasty, the dynasty was Zhu Yuanzhang, because Zhu Yuanzhang’s name had the word "Yuan" in it, so this was a taboo, so in the Ming Dynasty , No matter how small, large or small, the money is called "Tongbao".

This coin is extremely rare and has a high market value. The collection is also very good. The outline is clear, and the cowherd on the back is lifelike. In the coin category, this coin is worth collecting and investing in regardless of its appearance or value.
