In the antique market, the price of coins is determined by the number of coins in existence, and "the rarity is the most expensive". It depends not only on the age and circulation time, but also on the quantity of coins in the world. Chinese coins have a history of nearly 5000 years. From the pre Qin Dynasty to the Qing Dynasty, there are tens of thousands of kinds of coins. The currency of the pre Qin Dynasty, such as the Dao coin of Qi, Yan and Zhao, was expensive because of its long history and few quantity.
In the past ten years, coin collection has always been the focus of coin markets. Nowadays, as one of the non renewable resources, coins of the Republic of China still maintain their original charm and show extremely high "value".
The Double Flag coin was produced in the period of the Republic of China. The Republic of China has only existed for several decades in the history of China. Therefore, in the era of war and chaos, the coins can still be completely preserved after endless years. It is not easy to have high cultural relics collection value, historical and cultural value and art appreciation value.
The period of the Republic of China is not only a witness of the prosperity and decline of ancient Chinese feudal dynasty, but also a pioneer who opened the door of the world and knocked on the modern process. During this period, the Double Flag coin came into being. It was not only a witness of the founding of the Republic of China, but also a currency in circulation, a commemorative coin with historical significance, and its status was extraordinary. The biggest difference between the coins issued by the Republic of China and that of the Qing Dynasty is that the dragon pattern was replaced by the Jiahe pattern composed of rice ears, and most of the coins cast in various provinces were the cross of two sides of the national flag. It can be seen that the Double Flag coins of the Republic of China are precious physical witness of the historical period, and have epoch-making commemorative significance.
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，以当十面值的为主，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。 其中，双旗开国纪念币铜币不仅仅作为纪念中华民国的成立意义，同时，也作为流通币使用，后期，为了区分纪念和流通，铸造了如上图版本的铜币，一般以十文为主。正面以"中华民国",很少有以省份区分，并且，"当二十铜元"面值发行量很少，弥足珍贵!
After the victory of the 1911 Revolution, the Qing emperor abdicated and the Republic of China was founded. Sun Yat Sen, the pioneer of China's democratic revolution, took office as the provisional president of the Republic of China. In his "provisional presidential decree", he proposed that "new models should be published and commemorative coins should be forged". Subsequently, two mints in Wuchang and Nanjing took the lead in casting copper coins of "the founding of the Republic of China". The coins were mainly issued in the current ten denominations to replace the copper coins of the Qing Dynasty. This is the origin of the "commemorative coin of the founding of the Republic of China". Among them, the Double Flag founding commemorative coin is not only used to commemorate the founding of the Republic of China, but also used as circulating currency. In the later period, in order to distinguish the commemoration and circulation, the copper coins of the above version were minted, which were mainly composed of ten characters. With the "Republic of China" on the front, it is rarely distinguished by provinces, and "when twenty copper dollars" has a small par value, which is very precious!
This collection is made in Hunan Province as 20 copper yuan. On the obverse side of the coin, there is a national flag with two sides crossed in the center, with the words "made in Hunan Province" on the top, and the following value: when twenty copper dollars. The pattern on the back is Jiahe grain composed of rice ears. This copper coin is rare in the world and has high collection and investment value. The green rust on the copper coin also witnessed the deposition of its historical age. It is not difficult to see its obvious historical transitional characteristics. Although the copper coin has experienced many vicissitudes, its lines are still vaguely visible, so it has an indescribable collection and investment value. After the brewing of the currency market in recent years, the currency trading market based on mechanism currency is quietly heating up. In particular, coastal cities and the mainland market set off a copper investment fever. Copper coins are a large category of coin collection. Different editions of copper coins have their unique charm, which is worthy of investors' careful taste. In the market trading of ancient coins, this kind of Double Flag copper coins are more popular.
