Collectible coins encompass various categories, including standard issue coins, proof coins, and commemorative coins. In the United States, collectible coins such as the 1 cent (1c) to 50 cent (50c) denominations are popular among collectors. Proof sets, which include coins struck with a higher quality finish, were particularly notable from the San Francisco Mint in 1998. These proof coins have a mirrored surface and are often sought after for their aesthetic appeal and lower mintage figures.
