1912年民國成立后，孫中山就任中華民國臨時大總統。由于幣制尚未建立，晚晴機制銅元仍繼續大量流通使用。由于幣制混亂，臨時政府財政部長陳錦濤，于民國元年3月11日呈文大總統孫中山發行的銅幣與清朝最大的區別是龍紋被換成了由稻穗組成的嘉禾紋。各省鑄造的銅元大多為兩面叉的國旗圖案，并有“開國紀念幣”或“中華民國銅幣”字樣。
隨后武昌和南京兩處造幣廠率先鑄行了 “中華民國開國紀念幣”銅元輔幣，以十文面值的為主，在全國發行以取代清朝銅元。這就是“中華民國開國紀念幣” 銅元的由來，因為幣面都有‘雙旗圖案’故俗稱“雙旗幣”。因為錢幣分為中央和地方鑄造和不通刻板，其版別也極其復雜。
圖中藏品是一個“大圓國”版雙旗幣，該幣為機制銅元，錢幣正面兩面旗幟交叉而立，左為十八星旗，右為五色旗，旗后系有纓帶，靈動飄逸，雙旗寓意全國一統與民族大團結;上緣為“中華民國”四字，下緣鑄“開國紀念幣”五字，左右兩側分列長枝花卉。背面中央珠圈內鑄“十文”字樣，兩邊有禾穗、蓮葉紋盤繞，寓意豐民足歲;珠圈外鑄有英文面值和國別。這些特點與一般雙旗幣沒有明顯區別。“大圓國”版雙旗幣與一般雙旗幣的區別;民國開國紀念銅幣十文的字體為隸書大字，筆劃粗圓，不似一般的隸書那般清秀，國字為大圓框俗稱“大圓國”，正面無圈，面雙圈，小麥穗，珠圈外三點星。近幾年隨著廣泛收藏愛好者的喜愛和追捧，清末年間的古幣在國內市場的成交量也隨之上升，民國年間的錢幣也成穩定趨勢在逐漸升高，從而創造出一個又一個的傳奇故事。
After the founding of the Republic of China in 1912, Sun Yat-sen became the interim president of the Republic of China. Since the currency system has not yet been established, the late Qing mechanism copper yuan continues to circulate in large quantities. Due to the chaos of the currency system, the Minister of Finance of the Provisional Government Chen Jintao submitted a letter on March 11, the first year of the Republic of China, that the copper coin issued by the President Sun Yat-sen and the Qing Dynasty is the biggest difference between the dragon pattern and the golden grain made of rice ears. Most of the copper coins minted in various provinces are double-sided crossed national flag patterns, and have the words "Founding Commemorative Coin" or "Republic of China Copper Coin".
Subsequently, the two mints in Wuchang and Nanjing took the lead in coining the "commemorative coin for the founding of the Republic of China" copper yuan coins, mainly in ten denominations, and issued nationwide to replace the Qing Dynasty copper yuan. This is the origin of the "commemorative coin for the founding of the Republic of China" copper yuan, because the currency has a "double flag pattern" so it is commonly called "double flag coin". Because the coins are divided into central and local minting and different and rigid, their versions are also extremely complicated.
The collection in the picture is a double-flag coin of the "Great Yuan Country" version. The coin is a machine-made copper dollar. The two flags on the front of the coin are crossed. The eighteen-star flag is on the left and the five-color flag is on the right. There is a tasseled band behind the flag, which is flexible and elegant. The flag symbolizes national unity and national unity; the upper edge is the four characters "Republic of China", the lower edge is cast with the five characters "commemorative coin for the founding of the nation", and there are long branches of flowers on the left and right sides. The words "Ten Wen" are cast in the central bead ring on the back, with grains of grass and lotus leaves coiled on both sides, implying the prosperity of the people; the English face value and country are cast outside the bead ring. These characteristics are not significantly different from the general double flag coins. The difference between the "Dayuanguo" version of the double flag coin and the ordinary double flag coin; the font of the ten-character commemorative copper coin for the founding of the Republic of China is the official script, the strokes are thick and round, unlike the ordinary official script, the national character is a big round frame, commonly known as "大圓國" , No circle on the front, double circle on the face, wheat ears, three stars outside the bead circle. In recent years, with the love and pursuit of a wide range of collectors, the volume of ancient coins in the domestic market in the late Qing Dynasty has also increased, and the coins in the Republic of China have also become a stable trend and gradually increased, thus creating one after another. legend.
