The 1990 Denver Mint nickel (5 cents) is part of the United States coinage series, featuring Thomas Jefferson on the obverse and Monticello on the reverse. Collectors often seek out rolls of nickels from specific years and mints due to their historical significance and potential numismatic value. Coins minted at the Denver Mint typically have a "D" mintmark, distinguishing them from those produced at other facilities. As with many collectible coins, factors such as condition, rarity, and demand can significantly influence their market value.
