In the third year of the Republic of China, the signature version of Yuan Datou was a sample coin cast by the former Tianjin Mint. The most striking feature of this coin is that the words "L.GIORGI" or "L.G" are written on the right side of Yuan Shikai's head in English, which is the signature abbreviation of the sculptor "Rurgi George", commonly known as the signature big head. As for the T-shaped version, the silver dollar has no teeth and the edge is a T-shaped edge.
