This coin is part of the California Fractional Gold series, which was issued during a time when the gold rush in California led to a need for small denomination coins. Specifically, this piece represents a denomination of 50 cents and was minted in the year 1855. Despite its historical significance, the mint location for this particular issue is marked as "N/A," meaning it did not originate from a traditional U.S. mint, which is characteristic of fractional gold coins produced by private minters during that era. The coin is categorized simply as a "coin" type without any specific designer information available. Notably, certain physical properties such as width, height, diameter, and weight are listed as "0.00000000", indicating a lack of specific data for these measurements. Similarly, the mint mark is noted as "None," which is common for many California Fractional Gold coins. The coin is made from an unspecified material categorized as “Other,” reflecting the diverse types of metals that were often used in the production of these fractional coins, which were generally composed of gold, silver, or a mix of metals. Additionally, the mintage figure is reported as "0," which is unusual for coinage information and may indicate that specific records or details about its production are not available. Overall, this 1855 California Fractional Gold 50¢ coin stands as a significant piece of American numismatic history, representing the unique economic circumstances of its time and the need for fractional currency during the gold rush period.
