The designation "G 45 34" may refer to grading within the numismatic community, specifically the coin's condition according to a standardized scale. F.D. Kohler refers to a notable coin dealer or collector. The year 1850 denotes the coin's minting date, and San Francisco indicates the location of the mint, which was a prominent site for gold and silver coinage in the United States during the mid-19th century.
