Collectible coins, particularly U.S. nickels such as the 1940 5-cent piece, are popular among numismatists due to their historical significance and unique designs. The 1940 nickel features Thomas Jefferson on the obverse and Monticello on the reverse. These coins are often sought after in various conditions, with uncirculated examples commanding higher prices. Additionally, mint marks, which indicate the location of production, can impact their collectible value. Collectors often examine attributes like strike quality, surface condition, and rarity to determine a coin's desirability.
