Collectible coins such as the Jefferson Nickels, particularly those minted in 1998 at the San Francisco Mint, are sought after by numismatists. The Jefferson Nickel, originally introduced in 1938, features a portrait of Thomas Jefferson on the obverse and Monticello on the reverse. The 1998 issue, while not exceptionally rare, can attract collectors due to its uncirculated or proof versions. Additionally, the designation of "Five Cents" refers to the denomination associated with these nickels, while the "Half Dime" refers to earlier coins that were worth five cents, predating the nickel's introduction.
