1911年12月29 日，经辛亥革命后，已光复的17省代表在南京推选孙中山为中华民国临时大总统。1912年1月3日，中华民国政府宣告成立，清朝灭亡，在中国持续2000 多年的封建君主专制随之结束。民国成立时，由于币制尚未建立，除四川改铸大汉银币，福建改铸中华元宝外，主要的造币厂，大都仍沿用前清钢模铸造银币，以供流通需要。由于币制混乱，临时政府财政部长陈锦涛，于民国元年3月11日呈文大总统孙中山，鼓铸10万元纪念银币以为整顿。
On December 29, 1911, after the revolution of 1911, 17 provincial representatives who had recovered elected Sun Yat-sen as the interim president of the Republic of China in Nanjing. On January 3, 1912, the government of the Republic of China was founded and the Qing Dynasty was destroyed. The feudal autocracy which lasted for more than 2000 years in China ended. When the Republic of China was founded, because the currency system had not yet been established, except for the silver coins of Dahan in Sichuan and Zhonghua Yuanbao in Fujian, most of the major mints still used the steel mould of the former Qing Dynasty to cast silver coins for circulation. Due to the confusion of the currency system, Chen Jintao, the finance minister of the interim government, submitted a letter to Sun Yat-sen, the president of the Republic of China, on March 11, the first year of the Republic of China, advocating to cast 100000 yuan silver coins to commemorate the rectification.
1911年辛亥革命胜利后，清帝退位，中华民国成立。中国民主主义革命的先驱者孙中山就任中华民国临时大总统，并在颁布的“临时大总统令”中提出要“另刊新模，鼓铸纪念币”，随后武昌和南京两处造币厂率先铸行了 “中华民国开国纪念币”铜元辅币，以十文面值的为主，在全国大量发行以取代清朝铜元。这就是“中华民国开国纪念币” 铜元的由来。 无庸置疑，这种铜元的币名很明确，就是“中华民国开国纪念币”。根据钱币收藏界的一般共识，对一种钱币，应该把可以明确币名或显示钱币最主要特征的一面称为“面”，而把其相对的另一面称为“背”，据此我们应该把此币最能区别于前朝铜元,并具有鲜明的划时代革命和进步意义的有“中华民国开国纪念币”（以下简称开国纪念币）字样的一面称为面，而把其对应记值的另一面称为背。
After the victory of the 1911 Revolution, the Qing emperor abdicated and the Republic of China was founded. Sun Yat Sen, the pioneer of the Chinese democratic revolution, took office as the interim president of the Republic of China, and proposed in the "interim president's order" that "a new model should be published and commemorative coins should be drummed". Subsequently, two mints, Wuchang and Nanjing, took the lead in casting the "commemorative coins of the founding of the Republic of China" copper coins, mainly with a face value of ten Wen, which were issued in large quantities throughout the country to replace the copper yuan of the Qing Dynasty. This is the origin of the "commemorative coin of the founding of the Republic of China". There is no doubt that the name of this coin is very clear, that is, "the founding of the Republic of China commemorative coins.". According to the general consensus in the field of coin collection, for a kind of coin, we should call the side that can define the name of the coin or display the most important features of the coin "face", and the other side that can be opposite "back". Therefore, we should distinguish this coin from the copper dollar of the previous dynasty, And with a distinctive epoch-making revolutionary and progressive significance, one side of the words "Founding commemorative coin of the Republic of China" (hereinafter referred to as "Founding commemorative coin") is called the face, and the other side of its corresponding value is called the back.
After the founding of the Republic of China, the copper yuan continued to be widely circulated and used. In 1914, the copper coin was officially renamed "copper coin". The biggest difference between the copper coin issued in the Republic of China and that of the Qing Dynasty was that the dragon pattern was replaced by the Jiahe pattern composed of rice ears. Most of the copper coins made in each province are national flags with two forks, and have the words "Founding commemorative coins" or "copper coins of the Republic of China". This is only a very short period in the history of Chinese currency.
This "Double Flag coin" was made in Hunan Province for 20 articles. During the period of the Republic of China, it was a copper coin with unique design. The front circle of the coin is engraved with cross five-color flag and iron blood 18 star flag. The upper circle is written with "made in Hunan Province", and the lower circle is the value of the coin "when making 20 COINS".
此币背面圈外为英文字样“TWENTY CASH”和“THE REPUBLIG OF CHINA”，内圈则铸有枝叶繁茂的嘉禾稻穗纹，寓意“家和”，寓意国家注重农桑和百姓生活，画面造型极为和谐。此钱币整体色泽古沉，其字体笔法流畅，纹饰雕刻精致，边齿分明排列规则，深浅适度。 细看币面老化磨损程度自然，铜制质古韵熟旧，包浆醇厚，字口纹饰冲压力度适中，品相完好，虽然历经沧桑，但纹路依然隐约可见。 双旗币不仅仅具有纪念中华民国的建立意义，同时也作为流通币运用。此枚铜币现存世量不多，具有很高的收藏和投资价值，其见证了其历史年代的沉积，不难看出它明显的历史过渡性特征，该铜币历经沧桑，有着难以言表的收藏投资价值。
The reverse of the coin has two cash and the publishing of China on the outside, and the inner ring has the pattern of Jiahe rice with luxuriant branches and leaves, implying "family harmony", implying that the country pays attention to the life of farmers and the people, and the picture is very harmonious. The overall color of this coin is ancient and heavy. Its writing style is smooth, the decorative carving is exquisite, the side teeth are arranged clearly and regularly, and the depth is moderate. Looking closely at the aging and wearing degree of the coin, it is natural that the copper is ancient and mature, the coating is mellow, the punching pressure of the word mouth decoration is moderate, and the product is in good condition. Although it has gone through vicissitudes, the lines are still indistinct. Double Flag coin not only has the significance of commemorating the establishment of the Republic of China, but also is used as currency. This copper coin has a very high collection and investment value due to its small extant age. It has witnessed the deposition of its historical age. It is not difficult to see its obvious historical transitional characteristics. The copper coin has gone through many vicissitudes and has an indescribable collection and investment value.
The Double Flag coin issued in the Republic of China, as a well-known copper coin in China, is a reflection of the political, economic, cultural and artistic conditions in the period of the Republic of China. Therefore, its value has been found by more and more people, and it has been collected by more and more people. The development of high price double flag coin in the auction is amazing. It is understood that the overall market trend of Shuangqi currency is rising, with a very considerable prospect, which is clear.
