Collectible coins, particularly from the United States of America, include various denominations and special editions that are highly sought after by numismatists. The 1 cent (1c) coins, particularly those minted in 1986, are notable for their historical significance and connection to the long-standing tradition of American currency. Proof sets, such as those produced in San Francisco, represent a specific type of minting process that results in high-quality, mirror-like finishes. These sets often contain coins from different denominations and are produced in limited quantities, making them popular among collectors.
