从古到今，全世界都要用到钱币，当然，人们都有储蓄钱币的传统习俗，据了解，钱币收藏一般分为纸币、金银纪念币和古钱币三大类，而古钱币中银元一直是一大热点。因为银元材质珍贵，艺术价值高。同时，银币制作量比古钱和民国纸币少得多，加上清末、民国战乱连连等因素，一些较珍贵的银元品种存世量已稀少。

钱币之最要属收藏界公认顶级的珍贵银元“光绪纪念币双龙寿字币壹两”此钱币是清代光绪年间两广总督张之洞为纪念慈禧太后诞辰而铸造的，流传都很少，当今上海博物馆藏有该银元。

钱币其包浆入骨，熟旧自然，深打字口清楚，流通痕迹明显，边齿过关，龙鳞清晰，具有极高的投资价值和收藏价值。它有着历史熏陶，是价值很高的革命文物，具有深远的历史纪念意义；同时还是考古和研究中国历史文化难得的实物。

英文翻译：From ancient times to the present, coins have been used all over the world. Of course, people have the traditional custom of saving coins. It is understood that coin collections are generally divided into three categories: paper coins, gold and silver commemorative coins, and ancient coins. It has always been a hot spot. Because the material of silver dollar is precious, the artistic value is high. At the same time, the number of silver coins produced was much smaller than that of ancient coins and the Republic of China banknotes. Coupled with factors such as the late Qing Dynasty and the rebellion of the Republic of China, some of the more precious silver dollar varieties have been scarce.

  The most important coin is the precious silver dollar "Guangxu Commemorative Coin Shuanglong Shou Zi Yiliang" recognized by the collector circle. This coin was minted by Zhang Zhidong, the governor of Guangdong and Guangxi during the Guangxu period of the Qing Dynasty to commemorate the birth of Empress Dowager Cixi. The silver dollar is in the collection of the Shanghai Museum.   The coins are packed into the bones, mature and natural, deep typed with clear mouth, obvious circulation traces, edges and teeth are clear, and the dragon scales are clear. They have extremely high investment value and collection value. It has historical influence, is a revolutionary cultural relic of high value, and has far-reaching historical memorial significance; it is also a rare object in archaeology and research on Chinese history and culture.
