1968-D Lincoln Memorial Cent with Repunched Mint Mark (RPM)

The Lincoln Memorial Cent was introduced in 1959 to commemorate the 150th anniversary of Abraham Lincoln's birth. The 1968-D was minted at the Denver Mint, with over 2.8 billion pieces struck that year. During production, mint marks were hand-punched into working dies, occasionally resulting in doubled or repunched mint marks when the punch was applied more than once in slightly different positions. These repunched mint mark varieties (RPMs) occurred when the mint mark punch slipped or was repositioned during the die preparation process, creating a distinctive doubling effect visible under magnification. Repunched mint mark varieties are highly sought after by error and variety collectors who specialize in Lincoln cents. The 1968-D RPM varieties are cataloged and valued based on the prominence and clarity of the repunching. Collectors prize these coins for their uniqueness and the insight they provide into the minting process of the era. Such varieties appeal to numismatists who enjoy the challenge of discovering and attributing specific die varieties, making them more valuable than standard circulation strikes of the same date.
