The 2003 Denver 5-cent nickel is part of the United States' regular coinage and features the traditional portrait of Thomas Jefferson on the obverse and Monticello on the reverse. The Denver Mint produced these coins, contributing to the circulation of nickels during that year. Collectors often seek specific mint marks, such as the "D" mint mark found on Denver-produced coins, for their significance and rarity. Rolls of nickels can contain a mix of coins from various years and mint locations, making them popular among numismatists for searching for specific varieties or higher-grade specimens.
