Collectible coins, such as those from the United States of America, encompass a variety of denominations, including 1 cent (1c) to 50 cents (50c). One notable type of collectible coin is the Proof Set, which features coins that have been struck using a special process to create a high-quality finish and sharp details. The 1997 Proof Set, minted in San Francisco, includes coins from that year in pristine condition, making it desirable for collectors. These Proof Sets often serve as both a historical representation of the coins issued and a reflection of the numismatic artistry of the time.
