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。

由于袁大头银元铸造的时间长，参与铸造的造币厂多，因此，存世的袁大头银元的版别是非常多的，下面详细介绍一下：首先说1914年袁大头银元的版别就和其他年份都不一样，1914年袁大头银元的正面图案是袁世凯的侧面头像，上面的文字是：“中华民国三年”，在“年”字的后面没有“造”，其他年份的袁大头银元的“年”字后面都加上了一个字“造”。

藏品介绍

中文名称：民国三年袁大头

英文名称：Yuan dazhong in the third year of the republic of China

类别：杂项

规格：一枚

品相：美品

正面均为袁世凯五分侧面像，上列纪年，民国三年收藏价值是极高的，袁大头之所以会被称为袁大头主要是因为在这枚银元背后是印有袁世凯侧脸的“大头贴，并且这枚银元也是由他发行的，首先银元值钱的其中原因在于它和人民币不同，它从外国的传入期是由清朝开始袁世凯为了解决在辛亥革命后的军费问题以及个人地位提高的重要途径，从这里来说虽然他不受到欢迎但是银元背后的历史价值是不容小窥的。

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。

黑漆古包浆：古铜长期存放在大气中锈蚀机理分析紫铜、青铜、黄铜在大气中都很稳定，一般小于0.00015毫米/年，在铜表面会生成一层极稳定的保护薄膜，主要是碱式硫酸铜呈橄榄绿色，还会产生氧化铜（CuO）中黑色，硫化亚铜黑色，及氧化亚锡（SnO)棕黑色。年代越久则锈层加厚颜色也变深，俗称为“黑漆古”，若长期在手中把玩则会使表面光亮如镜俗称“传世古”。但在这类古铜中也产生电化学腐蚀，故是“哑声‘。若古铜长期在干燥的环境中（大气中或土中）也会产生氧化铜和氧化亚金星呈深黑色，俗称“黑漆古”

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，再看红圈所标记处，民字是多一点的，这也是与其它钱币很大的一个区别，下方红圈标记处，我们可以看到袁大头人像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。

这枚钱币黑漆古包浆自然，底光柔和，所谓包浆是自然形成的氧化层，也有认为手盘包浆，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，是钱币不再氧化，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。细看这三枚钱币品相完美，没有磕缺，损毁，变形等是不可多的收藏级铜币，建议收藏，传世。

英文翻译：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, the beiyang government decided to coin the national currency because there were more than 100 kinds of Chinese and foreign currencies in circulation, with different specifications, chaotic circulation, cumbersome conversion, and the public's resentment. In order to improve his dominance, yuan shikai had his head cast on the coin surface, from which the name "yuan dazhong" came.

Because big head silver casting a long time, yuan participation casting of mint, therefore, only yuen bulk silver bottle is very much, introduce in detail below: first of all, said big head silver bottle is 1914 yuan, unlike all the other years, big head silver positive pattern is in 1914 yuan yuan shikai's head appears in profile, the above words are: "three years of the republic of China," behind the word "year" without "made", other years of big head silver yuan are added at the end of the word "year" one word "build".

The collection is introduced

Chinese name: yuan daodong in the third year of the republic of China

English name: Yuan dazhong in the third year of the republic of China

Category: miscellaneous

Specification: one piece

Phase: beauty

Positive are five yuan shikai profile, the above calendar, three years of the republic of China collection value is extremely high, big head big head is called yuan yuan because behind this silver was printed with yuan shikai side face of the photo, and it also issued by his silver medal, the first silver valuable is that it, unlike the yuan, the reasons of it from foreign afferent phase consists of the qing dynasty to yuan shikai in order to solve the problem of the military after xinhai revolution as well as an important means to improve the personal status, from here, although he is not popular but the history behind the silver dollar value is not small peep.

Back jiahe two books, left and right interaction, the next tie belt, cast in the word "one round". 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.

Black paint the old wrapped slurry, bronze long-term in atmospheric corrosion mechanism analysis of copper, bronze, brass in the atmosphere is very stable, generally less than 0.00015 mm/year, in the copper surface generates a very stable layer of protective film, mainly alkaline type copper sulfate in olive green, also can produce copper oxide (CuO) in black, cuprous sulphur black, and stannous oxide (SnO), dark brown. The older the rust layer thickened color also become dark, commonly known as "black lacquer ancient", if long in the hand will make the surface as bright as a mirror commonly known as "handed down the ancient". But this type of copper also produces electrochemical corrosion, so it is "dumb". If the copper long-term in the dry environment (in the atmosphere or soil) will also produce copper oxide and Venus oxide dark black, commonly known as "black lacquer ancient"

Big head, big head in need three years of the republic of China yuan yuan this bulk circulation of at least one year of yuan, because he was a wrong version of the existence of general yuan big head is seven words, more than a "made" word, in only three years of the republic of China of all bulk yuan yuan big head there is no word, take a look at the red circle marked place, people, word is a bit more, this is also with the rest of the money, a big difference between the red circle below, we can see the big head portrait yuan less contact with the inner gear is an inner gear, it is also a professional identification of true and false coin important, this coin within the whole circle of the less a tooth, At that time the purpose is to counterfeit, and later copy of the money is not aware of this detail.

This coin black lacquer patina nature, downy light, the so-called wrapped slurry is a natural formation of the oxide layer, there are also think hands wrapped slurry, the two different, but at the same time have to protect the function of money, like to coin a layer of protective film on the plating, is money no longer oxidation, facilitate collection handed down from ancient times, if feel money is dirty, can wash, reoccupy cloth wipe, do not destroy the wrapped slurry, destroyed the wrapped slurry is equivalent to destroy the protective layer, more important is the wrapped slurry is the most simple and effective method for identification of new and old COINS. Look closely at the three COINS perfect, no knock, damage, deformation and so on is not much of the collection of grade copper COINS, suggest collection, handed down.
