California Fractional Gold coins are a type of collectible coin issued during the Gold Rush era, primarily between 1851 and 1856, to address the shortage of small denomination currency in California. These coins often feature denominations such as Ten Dollars and are typically made from gold or gold-plated materials. The 1851 Ten Dollar California Fractional Gold coins were minted in Philadelphia and are recognized for their unique designs and historical significance, appealing to both numismatists and collectors interested in the American West and gold mining history.
