3. Triangular circular plate. The word "mouth" in the circle on the back of this coin forms a "delta" shape, and other versions are "opening" shapes.

4. Open shell version. The bottom horizontal line of the word "shell" in the word "circle" of this coin is not connected with the vertical pen, forming an "open shell". There are obvious stripes on Yuan Xiang's epaulettes in this edition, and there is a straight line from top to bottom in Yuan's eyes, commonly known as "open eyes", which is not seen in other editions.

In the third year of the Republic of China, the back of Yuan Datou (triangle circle) 5. The word "Gansu" was added. This coin was cast by Lanzhou Mint in Gansu Province, imitating the old model of the three-year edition of the Republic of China. The word "Gansu" was cast around the Yuan image, and the rest were in the same shell version, with only tens of thousands of pieces cast.

6. Signature version. This coin is very rare. Tianjin Mint tried to cast sample coins, but there was no circulation. The coin is engraved with a vertical line of English letters "L.GioRGi" on the right side of the statue, which is the abbreviation of the signature of "Rurgi-Giorgio", a foreign coinage expert and Italian sculptor in China.

7. the edge of the "t" and the edge of the eagle ocean. These two kinds of coins are relatively rare, and they are the trial coins of Tianjin Mint General Factory.

The general edition of the eighth edition of Yuan Datou in the Republic of China has a large circulation, the steel mold is made in foreign countries, the writing conforms to the structure of Chinese characters, the font is unchanged, and the back picture of Jiahe is also standardized. It is characterized in that there is a thin tooth on the front inner side of the yuan-shaped brooch ornament, and there is no gap (there are gaps in other editions). In addition, there are several versions with less casting quantity, the main difference is that the word "made" is written differently:

1. The fourth stroke of the word "Zao" extends downward to form the word "Niu", but it is not connected with the word "Kou" below, so it is called "Niu" version.

2. Some words "Niu" and "Kou" are linked together, so they are called joint mouth books.

3. The word "mouth" in the word "made" lacks a horizontal line, forming a gap, which is called the notch version.

3. The main version of the nine-year edition of the Republic of China

The nine-year edition of Yuan Datou in the Republic of China includes nine-year fine hair, nine-year fine hair three times, nine-year medium hair, nine-year medium hair and small harvest, nine-year coarse hair and nine-year Hainan edition. In addition, there are rare versions, such as "Nine-year Niukou at 7: 00 am", "Nine-year gap" and "Nine-year epaulettes". In addition to the Hainan edition, other common forms of real money carving are extremely exquisite, which can be said to be more exquisite than the three-year Tianjin standard edition, especially the small print edition, with exquisite fonts, portraits and golden harvest patterns, which is also a major feature of the nine-year period. The following are introduced respectively:

1, nine-year fine hair: this edition is common, probably due to fine engraving. In the third edition of nine years (coarse, medium and fine), the main features are: the whole coin is finely carved, and the degree of exquisiteness is the highest in the big head series. The hair is a little bit, the beard has a strong three-dimensional effect, and the lower part of the beard is three or four locks (the middle hair version has only two locks, which is a simple way to distinguish the middle hair version from the fine hair version), and there is a small golden harvest on the back, and a small inner tooth is missing at nine o'clock (the place where the back of the fine hair is the easiest to distinguish between nine years and three years). The left ear is closed and the lower ear is closed.

2, nine years and three years back: this version is relatively rare, and so is the original light. Its main features are: the whole coin is finely carved, and the front is the same as the nine-year milliedition. The difference between it and the nine-year fine wool edition is mainly in the golden harvest face: big golden harvest (like Zhong Fa), there is no shortage of small internal teeth at nine o'clock, and the left ear is full and the left lower ear is not full.

3. Nine-year-old hair: rare, the original good product is more common than the coarse hair version and less common than the fine hair version. Its main features are: the whole hair is carved more finely than the coarse hair version, and the hair is in a wisp; The font is thicker, the hair is thinner, and the back is a bumper harvest, similar to the back of three years.

4. Nine-year-old Jiahe: Portraits and fonts are characterized by nine-year-old Jiahe, and there is a small Jiahe on the back (smaller than ordinary Jiahe and farther from the internal teeth, so it is called Xiao Jiahe). At nine o'clock, there is a small internal tooth on the surface of Jiahe, and the second ear on the upper left is open (please note that the nine-year fine-wool version is also a small Jiahe, but the ears are closed without awning, which is the difference between this version and the nine-year fine-wool back).

5, nine years rough: this version is more common, but it is not easy to get a good appearance of the original light. Its main characteristics are thick hair, thick font, round head for the first word of the year, hidden points on the mouth, hyphenation (occasionally), and a bumper harvest on the back, similar to three years.

6. Nine-year Hainan Edition: According to this edition, it was cast for Hainan Mint at the end of the Liberation War (belonging to Guangdong, also known as Guangzhou Edition), and the number of castings was small. Due to the age, good original products are not uncommon. Its main feature is that the whole coin is characterized by nine years of fine hair (with fine hair and small gold harvest on the back), but perhaps due to casting reasons such as mold or technology, the whole coin floats vaguely, which simply does not reflect the beauty of nine years of fine hair.

7, Niukou 7 o'clock in the morning year: This edition is rare, and the original light is hard to find. Its main features are as follows: the whole (Tou and Jiahe) is the feature of the nine-year edition, made of cow's mouth, with a 7-shaped year number and a nine-character pen with a bend.

Yuan Datou's signature edition was created in 1989: this edition is rare in the world, and only a dozen pieces can be seen in heaven. Its main features are as follows: the whole page was published in the middle of nine years, and the only difference is that the mouth of the word "Zao" consists of a gap, which is crisp and neat, which is different from that of ten years.

9. Nine-year epaulettes: This edition is rare, and it is absolutely hard to find a good original product. Its main features are as follows: the whole is similar to the nine-year edition, but the epaulettes are too large and the shoulder stars are large and flat. The Houjiahe has the characteristics of a big head for ten years (but not exactly the same), that is, the right ear tail is bent under the hook. In addition, there are small awns on the left ear.

There are mainly two kinds of nine-year editions: Yuanxiang unsealed edition and big-ear edition. The former is a common version with more casting quantity, while the latter has less casting quantity. The big ear version means that Yuan Xiang's ears are bigger than other versions and his collar is completely sealed. This version contains a lot of silver.

In addition, there are notch version, 7-point joint version, fine wool version, right hook version, broken pen version, big ear version and so on.

4. The main version of the ten-year edition of the Republic of China

There is not much difference between the ordinary version of Yuan Datou in the 10th edition of the Republic of China and the ordinary "Yuan Datou", and the casting quantity is large. Others write the word "year" as a vertical or "7"-shaped point, but the casting quantity is less.

In addition, there are T-point edition, notch edition, half-notch edition, double-notch edition, combined edition, ten-year eight-year edition, ten-year nine-year edition, open-ended flower edition, positive star edition, eccentric star edition, vertical-point edition, open-ended middle edition, right-notch middle edition, seven-point beard edition, big-point edition, lower-notch edition, failed edition, hexagonal star edition and so on.

In addition to the above version, there are many similar versions of the "Yuan Datou" one-dollar silver coin, which is difficult to name.
