This particular year, 1877, saw a total mintage of approximately 1,420,000 coins, making it relatively accessible compared to other dates in the series. However, Carson City coins are often sought after due to their historical significance and the lower number of coins that survived over the years. Collectors may look for various factors such as the coin's condition, the presence of original luster, and any wear or toning that could indicate its age and handling. Given its features and mintage, this 1877 Seated Liberty Half Dollar with a 'CC' mint mark holds both numismatic value and historical importance within American coinage.
