Collectible coins include various types such as proof coins, which are struck using specially polished dies to create a mirror-like finish. The United States Mint produces proof sets, which often include multiple coins packaged for collectors. The 1984 Proof Set, minted in San Francisco, features coins including the Lincoln penny (1c), and is sought after by collectors for its quality and historical significance. Collectors often seek these sets for their aesthetic appeal and as a way to preserve numismatic history.
