Collectible coins include various categories such as historical, commemorative, and bullion coins. The United States quarter, specifically the 25 cent denomination, has been produced since 1796, with notable designs reflecting American history. California Fractional Gold coins, minted during the Gold Rush era, often feature unique designs and varying denominations to facilitate transactions. The 1871 date may refer to specific issues or series that are sought after by collectors, though the details of "Unknown" likely indicate a lack of information on a particular coin or variety within these categories.
