With the changes of the times, the ancient coins extended by the change of Chinese dynasties are rich in layout and various in variety. Coins have a long history in our country. From the early barter era to coinage civilization, they witnessed the evolution of ancient society, politics, economy and culture, and carried the Millennium historical and cultural process, which has profound historical value, artistic value and collection value. Coins are the product of history and have irreplaceable cultural relics value. However, as time goes by, ancient coins are either destroyed in war or recovered by the government, recast or buried in the long river of history. The number of ancient coins existing in the world is becoming scarcer, and there is no limit to their collection and appreciation. In particular, the ancient coins of Qing Dynasty and Republic of China, which have a relatively recent history but belong to a special period, are quite special and of extraordinary value because they have witnessed the rise and fall of modern Chinese history and finance. 

The alternation between the Qing Dynasty and the Republic of China means that the feudal monarchy of the Chinese nation for more than 2,000 years collapsed and was replaced by the socialist regime. At the beginning of the establishment of the government of the Republic of China, that is, after the victory of the Revolution of 1911, the new national currency system had not yet been established, and the social economy and people's life were unstable, which led to the birth of the dual-flag currency of the Republic of China. It is only half a century before and after the issuance and circulation of copper coins in China. The double-flag coins of the Republic of China use the coinage template of the former Qing Dynasty. The coins are marked with the currency system on the front and changed into the flag shape with the dragon pattern on the back, which is an important part in the modern monetary history of China. It has witnessed the historical process of China's evolution from feudal society to semi-feudal and semi-colonial society and has unique historical significance. The layout of the Republic of China's double-flag currency is rich, with five denominations: 200, 100, 20, 50 and 10, which are different from the year number, copper, font size and writing strokes. However, because the Republic of China has not been in power for a long time and is limited by region and time, the circulation of double-flag coins in the Republic of China is not large, and the ancient coins remaining in the world are becoming scarce, which has become a popular coin in the eyes of collectors. 

In 1913 (in the second year of the Republic of China), Hu Jingyi, who succeeded Yin as the governor of Sichuan military government because Yin Changheng led the army to fight against rebellion, continued to cast "Han" and added a kind of copper coin with a large denomination of 200 Wen, which weighed seven money. The face value of "200 Chinese characters" in the central straight book of coins is divided into Jiasui patterns on both sides, with the sugar year number "Republic of China two years" on the upper side, the rust factory name "Sichuan Mint" on the lower side, and cruciferous stars on the left and right sides. There is a cross double flag in the center of the coin back, with a special circle on the outer ring, with the rust English "THE REPUBLIC OF CHINA" on the upper side and the rust English "200 cash" on the lower side. This is the only copper coin in Sichuan during the Republic of China that used English. The larger the denomination of cast steel, the thicker the profit. Hu Jingyi's two hundred copper coins. One can be exchanged for ten coppers and twenty coppers. A ten-Wen copper coin weighs two dollars, 20 coins weigh forty dollars, and a two-hundred-Wen copper coin weighs only seven dollars. Therefore, Hu Jingyi can plunder people's property by casting a two-hundred-Wen copper coin, which is sixteen and a half pieces of ten-Wen silver.

Since the national government issued a unified currency model later, coins in various places stopped casting and issuing, so the amount of casting was small and the circulation time was short, which was quite precious. In recent years, the collection market of coins is extremely hot, and it is not uncommon for coins to be auctioned at high prices. In particular, Chinese coins are widely loved by top collectors in the world. Whenever rare and precious coins with good appearance appear in auctions, it must cause crazy competition among collectors and capitalists! This double-flag 200-text copper coin made by Sichuan Mint in 2000, the collection has gone through endless years, but the grain is still clearly visible, and the patina on it has witnessed its historical accumulation, which has obvious historical transitional characteristics and has an indescribable collection value. What is even more rare is that this coin is a double wrong version of the front and back. Usually, this mechanism coin in the late Qing Dynasty and the early Republic of China has a wrong version that is commendable, not to mention a double wrong version. One is the front edge of the coin, with traces of brass overflow. The front and back of the second coin are nearly 90 degrees misplaced, which is even more rare. Moreover, copper coins are well preserved, and the Qian Wen and outline are clear, which has high historical value.
