Collectible coins encompass various types, including denominations like the five-cent nickel and half dime. The Jefferson Nickel, introduced in 1938, features a portrait of Thomas Jefferson and is made primarily of cupronickel. The 1948 Jefferson Nickel, minted in Denver, is particularly sought after by collectors for its historical significance and lower mintage. Coins from this era are often valued for their condition, mint mark, and any unique characteristics.
