I have a copy of Yuan Datou in the third year of the Republic of China in my hand, and I have looked up some information. There are many kinds in Yuan Datou, including L.Giorgi with English signature.
Signed 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.
Then yours is fake.
