湖南省造双旗币二十文经过战火的摧残，能完整地保留下来的已为数不多，很是稀少，弥足珍贵，具有很高的收藏价值。
1910年12月29日，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，中华民国政府成立，清朝灭亡，在中国延续了2000多年的封建君主专制统治结束。建国之初，由于货币尚未建立，货币制度混乱，孙中山就任中华民国临时大总统，在临时大总统令中提出“另刊新模，鼓铸纪念币”。民国元年三月十一日呈文大总统孙中山为纪念银币，临时政府财政部长陈锦涛于民国元年三月十一日致函。其后，武汉、南昌两地率先铸造了中华民国国币，并计划用来代替清币，这是建国纪念币的由来。与此同时，湖南省也在这一时期仿造湖南双旗币。
湖南双旗币普遍流通的都是当十文的，当时二十文只发行了22000枚，民国在中国历史上只存在了几十年，所以能够保存下来的钱币非常稀少。目前收藏市场上的全真纪念币虽然数量较多，但其正面镌刻了“二十文”楷体字、“中华民国”双面大字的全真纪念币，在今天的收藏市场上还不多见。由于钱币稀少而受到高端藏家的青睐，成为钱币交易市场的新热点。
此湖省造双旗币二十文保存完好，钱币正面中央左为星旗、右为五色旗，两面国旗上系结带相互交叉，上边铸“当货币”二十文，下铸「当钱」二十文，左右为星旗、右为五色。这枚钱币制作精良，钱文清晰，包浆极浓，品相较好。在混乱不安、烟火纷飞的民国时期，经过战火的摧残，能完整保存下来的已少之又少，极少，弥足珍贵，具有极高的收藏价值。
On December 29, 1910, after the Revolution of 1911, representatives of the 17 reclaimed provinces elected Sun Yat-sen as interim President of the Republic of China in Nanjing. On January 3, 1912, the government of the Republic of China was proclaimed and the Qing Dynasty fell, ending the feudal monarchy that had lasted in China for more than 2000 years. At the time of the founding of the Republic of China, because the currency system had not yet been established and the currency system was in confusion, Sun Yat-sen became the interim president of the Republic of China. Finance Minister Chen Jintao submitted a letter to President Sun Yat-sen on March 11, 2001, in which he drummed and minted a commemorative $100,000 silver coin to mark the rectification. Then Wuhan and Nanchang took the lead in minting the commemorative coins of the founding of the Republic of China, which are planned to replace the coins of the Qing Dynasty. At the same time, Hunan Shuangqi Coin was made in this period.
Hunan double-banner coins are generally circulated when the ten, twenty was only issued 22000, the Republic of China in Chinese history only a few decades of time, so can be retained very rare coins. Although there are many versions of coins in the Republican period, these Quanzhen commemorative coins with the lettering of "Twenty Characters" on the front and printed with the double flags of "Republic of China" are rare in today's collection market. Because the stock is scarce receives the high-end collector favor, becomes the coin exchange market a new hot spot.
The coins are made in Hunan Province. The left side of the coins is a star flag and the right side is a five-color flag. The two national flags are tied with each other. The four characters of "Made in Hunan" are cast on the outer edge of the coins. The value of "Made in Hunan" is cast. The flowers are arranged on the left and right sides of the coins. The back side of the coins is a grain of Jiahe grass composed of rice ears. This coin is exquisite in workmanship, clear in money, extremely thick in pulp, good in taste. Since the Double Flag Coins came into being during the turbulent and turbulent period of the Republic of China, after the devastation of the war, only a few of them could be completely preserved. They were very rare and precious, and had high collection value.
