Collectible coins include various types such as the Jefferson Nickel, which was introduced in 1938 and features a portrait of Thomas Jefferson. Specifically, the 1942 Jefferson Nickel is notable for its composition change during World War II, leading to the release of silver versions. Coins minted in San Francisco often have a "S" mint mark and are sought after by collectors due to their lower production numbers and historical significance. Additionally, the Half Dime, which is a denomination of five cents, was minted from the late 1700s until the mid-1800s and is collected for its rarity and historical context within U.S. currency.
