California Fractional Gold coins are a type of collectible coin that emerged during the California Gold Rush in the mid-19th century. These coins were produced in various denominations, often in values of ten dollars and less, to facilitate commerce in a gold-rich region with limited official currency. Struck primarily in the 1850s, many of these coins were minted in Philadelphia and feature designs that reflect local themes or prominent figures of the era. The 10 Dollar denomination is particularly sought after by collectors for its historical significance and scarcity.
