1. "O" notation.
that is, there is an "O"-shaped inscription in the golden harvest pattern, a horizontal "8" shape at the golden harvest knot, a tiny "O"-shaped circle in the upper left hole, and the front collar of Yuan Xiang's chin is not sealed, with wide epaulettes and five stars protruding.
2. Rough version.
yuan has thick hair and wavy hairstyle. Jiahe knot belt did not form a "8" knot, but an irregular circle was formed at the right side of a bundle of Jiahe knot belt.
3. Triangular circular plate.
the word "mouth" in the circle on the back of this coin forms a "△" shape, while 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". This edition of Yuan Xiang has obvious stripes on the epaulettes, and there is a straight line from top to bottom in Yuan's eyes, commonly known as "open eyes", which is also unknown in other editions.
5. add the word "Gansu".
This coin is made by Lanzhou Mint, Gansu Province, following the old model of the three-year edition of the Republic of China. The word "Gansu" is added to the left and right of Yuan Xiang, and the others are the same as the open shell edition, with a casting quantity of only tens of thousands.
6. signed version.
This coin is very rare. The Tianjin Mint tried to cast a sample coin, but it did not circulate. The coin is engraved with a vertical line of English letters "L.GioRGi" on the right side of the Yuan statue, which is the abbreviation of the signature of Italian sculptor "Rurgi Giorgio", a foreign coin-making expert in China.
7. The edge of the "T" and the edge of the eagle ocean.
These two kinds of coins are rare, and they are trial-minted by Tianjin Mint General Factory. The front and back patterns are the same as those of Yuan Daxiang in circulation, but differ only in the side teeth, which are T-shaped edges or eagle-shaped edges.
