1, rough version. Yuan has thick hair and wavy hairstyle. Jiahe tie did not form an "8" knot, but formed an irregular circle on the right side of a bunch of Jiahe tie.
2. 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.
3. 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.
4, add the word "Gansu" version. 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 Yuan Xiang, and the rest were open-shell versions, with only tens of thousands of pieces cast.
5. 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.
