北宋钱币。仁宗宝元二年至皇祐六年（1039～1054年）铸造。据巜文献通考》载：[……及改元宝元，仁宗特命以（皇宋通宝）为文，有篆真二种，又有铁钱。此皇宋通宝属于北宋的非年号钱。因南宋也铸有（皇宋钱），故此种皇宋通又被称作[北皇宋]。皇宋通宝铜质平钱有楷（亦称真书、隶、篆三种书体，均对读，可配配成对钱。该钱铸期达十六年之久，故而铸量极大，版别复杂，楷书面四星纹和背上星月纹钱，稀见。另有一种称[九叠篆皇宋通宝]的平钱，非常珍稀，此类钱也有不同之版式。铜钱还有类似折二之对钱对品，亦属罕见。铁钱仅见小平一种，有三种书体，皆对读，隶书版较少，背月纹者稀，除母钱外余者不奇。铁钱主要行用于北宋四川和河东（今山西部分地区）两处。 首都博物馆皇宋通宝九叠篆，径2.4 厘米 重3.9 克，钱文为九叠篆书，写在直径2.4 厘米的小平钱上，文字清晰，铸造技术精湛。“皇宋通宝”钱是北宋仁宗赵祯宝元元年（1038年）始铸的非年号钱。因鼓铸时间长，传世较多，钱文分真书和篆书两种；但以九叠篆为钱文的皇宋钱，传世和出土均极罕见。九叠篆书体，主要用于宋、元时期的印章，纸币上也常见，用于铜钱钱文的只有“皇宋通宝”，是历代钱币中绝无仅有的一例。一般认为皇宋通宝九叠篆不是流通货币，是试铸的样钱或开炉钱。
