Collectible coins are items sought after by numismatists and investors for their historical significance, rarity, and intrinsic value. In the United States, notable examples include the Twenty Dollar American Liberty Gold coins, which were minted in various years, including 1890. The Carson City Mint, known for producing coins with a distinctive "CC" mint mark, added to the allure of collectible coins from this era, as pieces from this facility are often more coveted due to their limited mintage and historical context.
