1910年12月29日，經辛亥革命后，已光復的17省代表在南京推選孫中山為中華民國臨時大總統。1912年1月3日，中華民國政府宣布成立，清朝滅亡，標志著中國兩千多年的封建君主專制隨之結束。民國成立后，由于幣制尚未建立，除四川改鑄大漢銀幣，附件改鑄中華元寶外，其他造幣廠開始延續前清朝鑄幣版式鑄造銅圓和銀幣以作整頓幣制和流通需要使用。中華民國雙旗幣鑄造期初，普遍流通的都是當十文、二十文的錢幣，因為受到時間和地域的限制始鑄量并不多，經過這么長的時間存世量已經非常稀少。
On December 29, 1910, after the Revolution of 1911, representatives of the 17 provinces that had been recovered were elected Sun Yat-sen in Nanjing as the interim president of the Republic of China. On January 3, 1912, the government of the Republic of China announced the establishment of the Qing Dynasty, marking the end of the feudal monarchy of China for more than two thousand years. After the founding of the Republic of China, as the currency system has not yet been established, in addition to Sichuan's transformation of the Dahan silver coin and the attachment of the Chinese yuan ingots, other mints began to use the former Qing Dynasty coinage casting copper and silver coins for rectification and circulation. At the beginning of the casting of the double-flag currency of the Republic of China, the coins that were generally circulated were ten-character and twenty-character coins. Because of the limited time and geographical constraints, the amount of casting was not much. After such a long period of time, the amount of the world was very rare.
