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。

民国九年袁大头

民国九年袁大头，可以看到袁大头胸前与内齿圈连接处，少一内小齿，是一种防伪手段，此币无论是看银光，压力，内齿，包浆，各方面都是表现十分开门的，是真品银币无疑，具有不菲的收藏价值。

背嘉禾二本，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，其中部分版本特殊，品相良好，存世稀少的珍品，更是不可估量。

银币压力：由于清朝自民国使用英国进口造币机器，压力高达五十吨，这个技术直到民国结束也未被超越，所以国内仿制银币多为图案模糊不清，内齿相连，并齿，所以很多专业的钱币收藏者，一看钱币说是压力不足，就变相的说是仿品，真品银币，图案清晰，无论是边齿，还是内次，都十分规整，且不会出现相连，并齿的情况，内齿长短一致，整齐划一，不会出现长短不一的情况，边齿也不会有斜齿，或者齿痕极浅的情况，因为仿币是用一种小型的设备，围着银币边缘，滚上一圈，我们称之为滚齿，很多阴阳齿等特殊齿轮是后滚出来的，在钱币边缘形成一圈滚痕，所以我们看钱币首要的就是看它的压力是否足够，线条是否清晰，没有瑕疵，多余的痕迹。

这枚钱币包浆自然，有典型的氧化银包浆，有包浆的钱币可以以此作为参考，所谓包浆是自然形成的氧化层，也有人为手盘包浆，两者不同，但同时都有保护钱币的功能，有如给钱币镀上一层保护膜，使钱币不再氧化，便于收藏传世，如果觉得钱币脏，可以用清水洗，再用棉布擦干，不要破坏包浆，破坏了包浆就相当于破坏了保护层，更重要的是包浆是鉴定新老钱币最简单有效的方法。细看这枚钱币品相完美，没有磕缺，损毁，变形等，是不可多得收藏级银币，建议收藏，传世。

英文翻译：Yuan Datou is one of the main currencies in circulation during the Period of the Republic of China. "Yuan Datou" is the colloquial name of yuan Shikai like a series of coins. It is called "Yuan Shikai like back Jiahe silver coin". In order to rectify the currency system, the Beiyang government made one silver coin. In February 1914, it promulgated the Thirteen National Currency Regulations and decided to implement the silver standard system. According to the Regulations on national currency, "the unit of price of kuping sterling silver is 6.48 per cent and its name is yuan", "a silver coin weighs 7.20 cents in total, silver 89 per cent and copper 11 per cent", and "there is no limit to the number of a silver coin", namely, a silver coin is the standard currency with unlimited legal compensation. 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".

After the fall of the Qing Dynasty, Yuan Shikai became president in April 1912. In view of the complexity of coinage and paper money at that time, there were more than 100 kinds of Chinese and foreign currencies in circulation with different specifications, chaotic circulation, cumbersome conversion, and resentment among the public, the Beiyang government also wanted to solve the military expenditure problem by means of currency reform, so it decided to coin and issue national currency. Yuan Shikai in order to enhance his dominance, his head cast on the currency, "Yuan Datou" from this.

Yuan Datou in the ninth year of the Republic of China

In the nine years of the Republic of China, Yuan Datou can be seen at the connection between yuan Datou's chest and the inner ring of teeth, with less one inner small tooth, which is a kind of anti-counterfeiting means. This coin is very open in all aspects, whether it is silver light, pressure, inner tooth and pulp. It is a genuine silver coin, and has a high collection value.

Back jiahe two, left and right interaction, the next knot belt, casting "one circle" two words. Over the years, in the silver collection area, has a name, is not always hear, that is "big head" yuan, especially in recent years, as the gold and silver price strength and market, and many there were more than the market price of the old silver dollar rise, some of these special version, good appearance, only rare treasures, is immeasurable.

Silver coin pressure: Since the qing dynasty republic of China, use the imported version machine, pressure up to 50 tons, the technology until the end of the republic of China, also not be transcended, so domestic imitation silver to design more blurred, internal tooth is linked together, and teeth, so a lot of professional coin collectors, a look at the coin, pressure is not enough, is a disguised form of replicas, genuine silver COINS, the pattern is clear, both side of tooth, Or within time, very neat, and there will not be connected, and teeth, the tooth length is consistent, uniform, there will be no length is differ, there will be no edge of helical, or teeth marks very shallow, because imitation coin is made of a small device, around silver edge, roll in a circle, we call the roll teeth, Yin and Yang are a lot of teeth after special gear is rolled out, A circle of rolling marks is formed on the edge of the coin, so the first thing we look at the coin is to see whether its pressure is enough, whether the lines are clear, there are no defects, and excess traces.

This coin patina nature, there is a typical wrapped slurry, silver oxide has patina of COINS can be as a reference, the so-called wrapped slurry is a natural formation of the oxide layer, also some people to hand wrapped slurry, the two different, but at the same time have to protect the function of money, like a plated coin on a layer of protective film, make money no longer oxidation, facilitate collection handed down from ancient times, if feel money is dirty, can wash, Then dry it with cotton cloth. Do not destroy the patna, which is equivalent to destroying the protective layer. More importantly, the patna is the simplest and effective way to identify new and old coins. Take a close look at this coin with perfect appearance, no damage, damage, deformation and so on. It is a rare collection of silver coins. It is recommended to collect and pass down.
