The Jefferson Nickel, issued by the United States Mint, was first released in 1938 and features a portrait of Thomas Jefferson on the obverse and Monticello on the reverse. The 1977 Jefferson Nickel, produced in Denver, is made of a copper-nickel alloy and weighs 5 grams. The coin is particularly notable for its design and historical significance, making it a popular collectible among numismatists. The term "Half Dime" historically refers to a coin denomination that was once equivalent to five cents, but is usually associated with earlier coins minted before the introduction of the nickel.
