As of February, 2020, the most precious and rare is Yuan Shikai's signature edition in the third year of the Republic of China (the Latin signature "L GioRGi" by Italian sculptor Rurgi Giorgi is engraved on the right side of Yuan Shikai), which is a rare treasure in modern silver coins.

Yuan Datou is actually a silver coin issued by Yuan Shikai during the Republic of China. There are several versions of Yuan Datou, and the values of different versions are definitely different.

Rare and precious Yuan Datou style:

1, 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.

2. Add the word "Gansu". 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.

3. 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.

4, "T" side, eagle ocean side. These two kinds of coins are relatively rare, and they are the trial coins of Tianjin Mint General Factory. The front and back patterns are the same as the general "Yuan Datou" in circulation, but they are different on the side teeth, which are T-shaped edges or eagle-shaped edges.
