孙中山头像中华民国开国纪念币（俗称“小孙头”或者“孙小头”）来历，至1911年底辛亥革命之后，1912年1月3日，中华民国政府成立，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。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。
坐洋，根据1952年在人民银行内部出版的《银元图说》，其正式名称应为安南银元，亦称“坐人”、“法光”、因为这种银币正面所铸的自由女神坐像头上的花圈有光芒七束，俗称“七角”。但为了叙述方便下文仍采用“坐洋”的说法。
