袁大头是民国时期主要流通货币之一，“袁大头”是对袁世凯像系列硬币的口语俗称，严谨点说叫“袁世凯像背嘉禾银币”。北洋政府为了整顿币制，划一银币，于民国三年（1914年）二月，颁布《国币条例》十三条，决定实行银本位制度。《国币条例》规定：“以库平纯银六钱四分八厘为价格之单位，定名为圆”，“一圆银币，总重七钱二分，银八九，铜一一”，“一圆银币用数无限制”，即以一圆银币为无限法偿的本位贷币。根据这一规定，于1914年12月及1915年2月， 先后由造币总厂及江南造币厂开铸一圆银币，币面镌刻袁世凯头像，俗称“袁头币”或“袁大头”。
清朝灭亡之后，1912年4月袁世凯出任大总统。北洋政府鉴于当时铸币、纸币十分复杂，流通的中外货币在百种以上，规格不一，流通混乱，折算繁琐，民众积怨，同时也想借助货币改制以解决军费问题，便决定铸发国币。袁世凯为了提高自己的统治地位，把他的头像铸于币面，“袁大头”由此而来。
签字版袁大头
民国三年袁大头签字版：此枚中华民国三年袁世凯像壹圆“L.GIORGI”签字版银币，该币最显著特征就是币的正面袁世凯五分侧面向，在右侧有英文“L.GIORGI”或简写“L.G”字样，由意大利籍技师鲁乔奇(Luigi Giorgi) 雕刻制模，数量极少，市场价值高。
袁大头中的极品民国三年袁大头，这一年的袁大头发行量最少，因为他在当时是一个错版的存在，一般的袁大头都是七个字，多了一个‘造’字，在所有袁大头中只有民国三年的袁大头是没有造字的，民字是多一点的，这也是与其它钱币很大的一个区别，我们可以看到袁大头人像胸前与内齿接触的地方是少一个内齿的，这也是内行人鉴定钱币真假重要的一点，这枚钱币整圈就少这一个内齿，当时的目的就为了来防伪的，而后期仿制的钱币是没有注意到这个细节的。
背面嘉禾二本，左右交互，下系结带，,中铸“壹圆”二字。这些年，在银元收藏界，有一个名字，始终不乏耳闻，那就是“袁大头”，特别是这几年，随着金银价格走强以及市场的火爆，许多老银元的市场价格都有了多倍的涨幅，品相良好，存世稀少的珍品，更是不可估量。
背嘉禾”，美禾，茁壮之禾，硕大之禾，祥瑞之禾也。东汉许慎《说文》云：“禾，嘉谷也。以二月而种，八月始熟，得时之中，故谓之禾。”王充《论衡·讲瑞篇》云：“嘉禾生于禾中，与禾中异穗，谓之嘉禾。”古人多以“嘉禾”为祥瑞之物，与甘露醴泉并称。如班固《汉书·公孙弘传》云：“甘露降，风雨时，嘉禾兴。”也就是生长得特别茁壮的禾稻，古人视嘉禾图案为吉祥的象征。
在中国钱币上就有嘉禾图案，现在国徽上就有，最典型的嘉禾纹样就是“袁大头”上的背后的嘉禾图案。

According to this regulation, in December 1914 and February 1915, the Minting Factory and jiangnan Mint successively cast a yuan silver coin, with yuan Shikai's head engraved on the coin surface, commonly known as "Yuan Tou coin" or "Yuan Datou".

Yuan Shikai in order to enhance his dominance, his head cast on the currency, "Yuan Datou" from this.
