清宣统三年(1911)天津造币总厂铸。当时清政府欲统一币制，聘请海外高级技师精心设计制造了这套宣统三年大清银币，计有六、七种版式，长须龙是其中之一。新币刚试铸成功，正逢武昌起义，于是大部分新版银币胎死腹中，只留有少量样币。长须龙因背面龙首之须特长而得名，属于试样性质，因图案精致、存世稀少而受人重视。大清银币是清朝末年宣统年间的一种机制币，由于是机器制作，所以鉴定难度更大，那么，如何鉴定大清银币的真假呢？大清银币根据背后的龙纹可分：长须龙，短须龙，曲须龙，反龙，大尾龙。

在钱币收藏界享誉盛名的宣三系列中，有“长须龙普通面”，以及“曲须龙签字版”，此二者仅次于“短须龙”，数量比“反龙”、“长须龙”、“大尾龙”都要稀少。如再算上枝叶、字体、签字内容的不同，那么版别更多。据孙浩《百年银圆》推测，按照龙形图案的设计不同，可以认为“曲须龙”“反龙”“大尾龙”由乔治(Giorgi)亲自操刀或者领衔，雕工上注重立体及线条流畅美感，“长须龙”“短须龙”由余子贞领衔的中国雕刻师团队完成，雕刻风格显得比较抽象。这符合中西相同历史时期的审美情趣，一如郎世宁之于宫廷书画。从设计风格上来说，前三者比较“写实”，符合西方钱币主体人或动物具象，而后二者则偏向“写意”，以突出龙图高高在上、威严霸气之气度，也摒弃了宣二水龙困在圈内的束缚感。事实上，除了“曲须龙”，因为“比稿”而诞生了其余四种“淘汰”方案里的精美样币，而这些具备中西文化融合方案的龙洋样币，无疑是大清龙洋巅峰之作的集大成者，也成了钱币收藏中难得一见的珍品，更是国内外各大拍卖会钱币专场的贵宾，无一不是各大实力藏家竞相追逐的对象。

It was cast by Tianjin Mint in the third year of Xuantong of the Qing Dynasty (1911). At that time, the Qing government wanted to unify the currency system and hired senior overseas technicians to carefully design and manufacture this set of silver coins of the three-year reign of Xuantong. There were six or seven formats, of which long Xulong was one. The trial coinage of the new coins was just successful, which coincided with the Wuchang Uprising, so most of the new silver coins were stillborn, leaving only a small number of sample coins. The long beard dragon is named after the beard specialty of the dragon head on the back. It belongs to the nature of sample. It is valued for its exquisite pattern and rare existence. The silver coins of the Qing Dynasty were a kind of mechanism coins during the Xuantong period at the end of the Qing Dynasty. Because they were made by machines, it was more difficult to identify. So, how to identify the authenticity of the silver coins of the Qing Dynasty? The silver coins of the Qing Dynasty can be divided according to the dragon pattern on the back: long beard dragon, short beard dragon, curved beard dragon, anti dragon and big tail dragon.

Among the famous Xuansan Series in coin collection, there are "ordinary face of long beard dragon" and "signature version of Qu beard dragon", which are second only to "short beard dragon", and the number is rarer than "anti dragon", "long beard dragon" and "big tail dragon". If you count the differences in branches, fonts and signature contents, there will be more editions. According to SUN Hao's Centennial Silver Circle, according to the different designs of dragon patterns, it can be considered that "curved beard dragon", "anti dragon" and "big tail dragon" are personally operated or led by Giorgi. Sculptors pay attention to the beauty of three-dimensional and smooth lines, "long beard dragon" and "short beard dragon" are completed by the team of Chinese sculptors led by Yu Zizhen, and the carving style is relatively abstract. This is in line with the aesthetic taste of the same historical period in China and the west, just as Lang shining was in court calligraphy and painting. In terms of design style, the first three are more "realistic", which is in line with the concrete image of human or animal, the main body of Western coins, while the latter two prefer "freehand brushwork", so as to highlight the lofty and majestic demeanor of the Dragon Figure, and also abandon the sense of bondage of Xuaner water dragon trapped in the circle. In fact, in addition to "Qu Xulong", the other four kinds of exquisite sample coins in the "elimination" scheme were born because of the "comparison", and these Longyang sample coins with the integration scheme of Chinese and Western culture are undoubtedly the epitome of the peak works of Longyang in the Qing Dynasty. They have also become rare treasures in the coin collection, and are also the VIP of the coin special session of major auctions at home and abroad, None of them is the object of great strength collectors.
