A misaligned die error occurs when one of the coin dies shifts horizontally from its correct position, causing the design on one side to appear off-center while the other side remains properly centered. The key difference from an off-center strike is that the coin retains its full, normal rim — only the design is shifted, not the blank itself.
In a coin press, the upper and lower dies must be precisely aligned. When one die shifts — from loose mounting, worn components, or a mechanical issue — the design it impresses lands off-center relative to the rim. The collar die still constrains the planchet normally, so the coin is the correct diameter with a full rim.
Significant misalignment — where the design nearly touches the rim on one side — is more collectible. Minor misalignment under 5% is common and generally carries little premium. Higher denominations with misaligned dies are scarcer.

Scan Your Coin NowA misaligned die coin has a full, normal rim with the design shifted on one side. An off-center strike shows a missing rim and blank metal crescent because the planchet was mispositioned, not the die.
Minor misalignments are fairly common, especially on high-volume production runs. Significant misalignments where the design nearly reaches the rim are much scarcer and more collectible.
It's possible but uncommon. Usually only one die — typically the upper (hammer) die — shifts. If both were misaligned, the designs on both sides would appear off-center.
Compare the rim width at the narrowest and widest points on the affected side. The difference indicates the approximate shift distance.
