This is a rare example of a California Fractional Gold coin, specifically a 50-cent denomination, minted in 1853 in Philadelphia. These coins are noteworthy as they were created during a time when small denomination gold coins were in high demand due to the California Gold Rush, which significantly increased the availability of gold. The coin features a distinctive design that reflects the era, although the specific details of the designer are not available (denoted as 'N/A'). It does not have a mint mark, indicating that it was struck at the Philadelphia Mint. The properties listed indicate that the coin does not have specific measurements for width, height, diameter, or weight, but it is categorized as a Mint Strike, meaning it was produced directly from a die that has not been used before. The material of the coin is classified simply as "Other," which likely refers to the unique compositions used in fractional gold coins of this type. California Fractional Gold coins were often made from a mix of metals to resemble the value of gold while remaining affordable and practical for use in everyday transactions. Notably, the mintage for this particular coin is listed as zero, which may refer to a lack of recorded issues or production-related discrepancies, enhancing its rarity in the numismatic market. As a type of currency, it is from the United States of America, signifying its role in the American monetary system during the mid-19th century. Collectors and numismatists often seek out California Fractional Gold pieces due to their historical significance and connection to the Gold Rush period, making this particular 50¢ coin a fascinating component of American coinage history.
