Collectible coins, such as those issued by the United States of America, can encompass a wide range of types, including commemorative coins, bullion coins, and those produced in special finishes like Proof coins. A notable example is the 1995 Proof Set, which includes coins minted with a high-quality finish, protected from wear and oxidation. These sets often appeal to collectors due to their limited mintage and presentation, making them valuable for both numismatic and investment purposes. The 1 cent coin, or penny, is particularly sought after in collectible form, especially when part of a complete Proof Set from a specific year.
