Collectible coins, particularly from the United States, encompass a range of types, including circulating coins, commemoratives, and proofs. The 1 cent (1c) coin, commonly known as the penny, is a popular focus among collectors. Proof sets, such as those minted in 2016 at the San Francisco Mint, feature coins that have been struck with high-quality techniques, producing a mirror-like finish and sharp details, making them highly sought after by numismatists. These sets typically include various denominations, showcasing the artistry and craftsmanship of U.S. coinage.
