The collectible coin known as the 1959 Denver nickel, part of the United States coinage, is a five-cent piece that features the depiction of Thomas Jefferson on the obverse and Monticello on the reverse. This particular year marked the transition from the original design to the inclusion of the "profile" design. Collectors often seek out 1959 Denver nickels due to their potential rarity and condition, with those in uncirculated or high-grade condition being more valuable. Rolls containing multiple nickels from this year can also be of interest to coin enthusiasts.
