Collectible coins are specially minted coins that are often sought after by collectors for their historical significance, rarity, or artistic design. In the United States, collectible coins include denominations such as 1 cent (1c) and 50 cents (50c), which can feature various designs over the years. Proof Sets, which include coins that are struck with a higher quality finish, were popular among collectors; the 1971 Proof Set included coins minted in that year, showcasing their unique characteristics and often higher value compared to standard circulation coins. These sets typically include a variety of denominations and are packaged in protective cases to maintain their condition.
