Collectible coins, particularly those from the United States, encompass a variety of types that appeal to numismatists. One of the notable issues in 2016 was the release of Proof Sets, which included specially minted coins designed for collectors, characterized by their high-quality finish and mirror-like surfaces. The 1-cent coin, commonly referred to as the penny, is often featured in these sets, highlighting its historical significance and varying designs over the years. Collectors often seek out these Proof Sets to enhance their collections and preserve examples of U.S. currency in pristine condition.
