I recently bought a small jade item and attempted to translate the seal on the bottom. After many hours of searching, I was unable to translate the characters. I believe they are Chinese characters, found some similar looking characters in small seal script but nothing matching what I have. Any help would be appreciated.
the character is a type called 经典繁方篆，a old standard chinese character around 1300BC to 1046BC
天福 is the name of a silver shop at TianJin during the period of the Republic of China(1912-1949)
纹银 means standard silver in ancient China
so the mean may be 天福's standard silver.
this probably a gift for their customers.
