孙中山开国纪念银币，俗称小头，是民国时期流通的货币之一。是第一枚将大总统头像替换皇家龙图的国币。就任临时大总统，上缘“中华民国”下缘“开国纪念币”为碑刻隶书体无疑，然细观之，背中央直读“壹圆”字样体似隶非隶，似楷非楷，民国14年，国民政府又在广州成立，民国15年迁武汉，民国16年(公元1927年)定都南京。 

         为纪念国父孙中山丰功伟绩，中央所铸货币均用国父像，南京、天津诸造币厂于民国16年、17年重新铸造中华民国孙像开国纪念币。由于该币正背面图案比较正规，中英文没有差错，又设置六角星，故称其为普通六角星版。由于当时发行量很少，导致目前存世量更少，有很高的收藏价值。民国十六年北伐战争胜利，国民政府定都南京，南京造币厂先取原模，重铸孙中山开国纪念币，后又改动币背面的英文和花边(六角星)，铸成新版，俗称“小头”。成为旧中国的主要流通货币。 

        中华民国开国纪念币是1911年12月29 日经辛亥革命后，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。民国成立时鼓铸的纪念币。由于币制尚未建立，除四川改铸大汉银币，福建改铸中华元宝外，主要的造币厂，大都仍沿用前清钢模铸造银币，以供流通需要。由于币制混乱，临时政府财政部长陈锦涛，于民国元年3月11日呈文大总统孙中山，鼓铸10万元纪念银币以为整顿。图案采用大总统孙中山肖像，以后的通用银币再改花纹式样。孙中山令财政部行文，同意鼓铸纪念币，并命令其余的通用银币新花纹，“中间应绘五谷模型，取丰岁足民之义，垂劝农务本之规”，训令财政部速制新模，分令各省造币厂照式鼓铸。不久，财政部就颁下新模给江南(南京)、湖北、广东等造币厂依式铸造，这就是“中华民国孙中山像开国纪念币”的由来。         中华民国开国纪念币孙小头壹圆，属机制币，形制规整，造型精巧，色泽纯正明亮，包浆自然醇厚，正反纹饰清晰，非常难得。钱币设计独特，构图新颖，正面珠圈内为孙中山侧面肖像，鼻梁高挺，目视前方，刻画细致；珠圈外上端环有“中华民国”四字，下端铸有“开国纪念币”五字，字体样式美观，引人注目，左右各饰长枝花。钱币背面正中央“壹圆”二字十分显目，下方以两支嘉禾装饰，珠圈外环绕“MEMENTO”（汉译为纪念币）和“BIRTH OF REPUBLIC OF CHINA”（汉译为中华民国诞生）英文字样，左右上侧分列六角星。众所周知，1911年辛亥革命胜利，清帝被迫退位，孙中山等人成立了中国民国。同时，颁布的政令中指出要另邗新模，鼓铸纪念币。因此，武昌和南京两处造币厂铸造了中华民国开国纪念币，其中以铜元辅币，以十文面值为主，在全国大量发行，目的在于取代清朝铜元。孙中山开国纪念银币，俗称小头，是民国时期流通的主要货币之一。是第一枚将大总统头像替换皇家龙图的国币，这意味着宣告清王朝统治的结束，中国从此进入共和制的新纪年。此外，币面镌刻中英文字，意在告知外国人，中国新的开放时代来临。在集藏领域，向来对重大历史事件高度敏感的金银币收藏市场，会赋予藏品独特的价值，它的行情也会顺势火爆。

The design uses the portrait of President Sun Yat-sen, after the general silver coin to change the pattern. Sun Yat-sen ordered the Ministry of Finance to issue a document approving the casting of commemorative coins and ordered new patterns for the rest of the common silver coins. "A grain model should be painted in the middle to take the interests of the rich and the full of people and to advise the rules of agricultural affairs." Sun ordered the Ministry of Finance to make the new model quickly and ordered the mints of each province to make the new model according to the pattern. Soon, the Ministry of Finance issued a new model to the south of the Yangtze River (Nanjing), Hubei, Guangdong and other mints in accordance with the casting, which is the origin of the "founding commemorative coin of the Republic of China like Sun Yat-sen".
