Collectible coins are specialty coins that are sought after by collectors for their historical significance, rarity, and aesthetic appeal rather than for their face value. The United States Mint issues a variety of collectible coins, including commemorative editions and annual Proof Sets. The 2021 Proof Set, produced in San Francisco, features high-quality coin strikes with a mirror-like finish, showcasing various denominations, including the iconic 1 One Dollar coin. These Proof Sets are typically encapsulated to preserve their condition and are often included as part of a collector's portfolio.
