Collectible coins include a variety of items sought by numismatists, encompassing historical, rare, and valuable pieces. The United States quarter, particularly the 25 cents coin, features numerous designs and series, with collectors often focusing on specific years or states. California Fractional Gold coins, issued during the Gold Rush era, are small denomination gold pieces that varied in design and were used to facilitate commerce. The 1878 Morgan silver dollar is a notable example of U.S. coinage and holds significant interest among collectors for its historical context and aesthetic appeal. Coins designated as "Unknown" may refer to those with unclear provenance or without identifying features that establish them as recognized collectible items.
