Collectible coins include various types such as the Jefferson Nickel, which was first issued in 1938 as a replacement for the Buffalo Nickel. The 1945 Jefferson Nickel, minted in Denver, is part of a series known for its design featuring Thomas Jefferson on the obverse and Monticello on the reverse. The coin is composed of a copper-nickel alloy and is popular among numismatists for its historical significance and variety in mint marks. Additionally, the term "Half Dime" refers to early 5-cent coins made of silver, which are now considered rare collectibles.
