Collectible coins typically encompass various categories, including commemorative coins, bullion coins, and circulation coins. In the United States, coins are often categorized by their denominations, such as 1 cent (1c) and 50 cents (50c). Proof Sets are specially minted coins that feature a higher level of detail and a polished finish, often sought after by collectors. The 1995 San Francisco Proof Set, for example, is notable for its inclusion of coins struck at the San Francisco mint, making it a popular choice among enthusiasts for its quality and limited availability.
