Collectible coins are specially minted coins that often serve as investments or items of numismatic interest. In the United States, various types of collectible coins include the 1 cent (1c) coins, often referred to as pennies. Proof sets, such as those from 2012 minted in San Francisco, contain coins that are struck with a higher level of detail and finish, making them suitable for collectors due to their quality and limited production. These coins typically feature a mirror-like background and frosted designs, enhancing their visual appeal.
