As a denomination of 50 cents, it represents part of a unique and historically significant period during the California Gold Rush, when smaller denomination coins were needed for everyday transactions. The design details for this specific coin are not attributed to a known designer and it features no mint mark, which is characteristic of some issues from this series. Although the measurements for width, height, diameter, and weight are not specified, such coins typically have dimensions that make them suitable for handheld use and storage. Manufactured as a mint strike, this coin is part of a production designed to circulate among the public, although its exact mintage remains unspecified, indicating that it might be rare. The material composition is listed as "Other," which likely refers to a non-standard gold alloy used during this period.
