“孙币”铸于民国十六年说质疑傅为群“孙币”即孙中山开国纪念币，俗称“小头”，有多种版别，其最常见者之明显特征为“六角星”花纹（图一）。钱币界一般多认为此币“铸于民国十六年”基本已成定论。但是，笔者近来查阅２０年代上海银行公会档案，发现此说有误，故提出商榷意见。１９２７年，北伐胜利，６月８日国民政府财政部饬令停铸袁头币，改铸孙中山头像币。据南京造币厂厂长汤钜呈称：“职厂遵饬改铸孙先总理像新式国币，因绘样镌模种种手续尚需时日，在新模未成以前奉准暂用民国元年先总理开国纪念币旧模印铸，以济金融，成色重量仍照旧例办理，现在业经出币，已分运中国、交通、中南、盐业、大陆、金城、四明各银行分别销售，除将新模督促进行，一俟成就，立即更换所有现铸纪念新币。”①以上史料说明：１９２７年（民国１６年）开铸的“孙币”用的是旧模，即民国元年（１９１２年）开国纪念币的旧模。此币于１９１２年３月由南京造币厂铸造，正面为孙中山侧面像，中文：“中华民国开国纪念币”，背面为英文“中华民国”及“壹圆”，当中则为中文“壹圆”字样，“五角星”在下面两旁，钱币界称“下五角星”（图二）。所以此种“下五角星”有铸于１９１２年的，亦有铸于１９２７年的。又据南 “Sun coins” cast in 16 years of the Republic of China, said that questioned Fu Wequn “Sun Moon” that Sun Yat-sen commemorative coins, commonly known as “small head”, there are many versions, the most common feature of the obvious “Hexagram” pattern one). The coin sector generally think that the currency “cast in the Republic of China sixteen years” has basically reached a conclusion.
