Copper-nickel five-cent coin, 1984-D Jefferson Nickel with Double Die Reverse (DDR) error issued by the United States Mint

The Jefferson Nickel was first introduced in 1938, replacing the Buffalo Nickel, and features President Thomas Jefferson on the obverse and his home Monticello on the reverse. The design was created by Felix Schlag and has remained largely unchanged for decades. The 1984-D issue was minted at the Denver Mint, and certain specimens exhibit a double die reverse error, where the die impression was duplicated during the minting process, creating visible doubling on the reverse design elements. Double die error coins are highly sought after by numismatists and error coin collectors who appreciate the rarity and uniqueness of minting mistakes. The 1984-D DDR Jefferson Nickel represents a fascinating example of mint error coinage, appealing to specialists who focus on varieties and errors in modern U.S. coinage. These coins command premium prices over standard circulation strikes, with value depending on the strength and visibility of the doubling, as well as the coin's overall condition and grade.
