The 2021 Denver 5-cent nickel roll contains coins minted at the Denver facility in the United States. Nickels, which are made primarily of a copper-nickel alloy, feature the image of Thomas Jefferson on the obverse and his home, Monticello, on the reverse. The 2021 nickels are part of the standard series but may hold additional collectible value depending on their condition and demand among numismatists. Rolls of nickels can be a convenient way for collectors to acquire multiple coins at once, and the Denver mintmark signifies the location where these specific coins were produced.
