Misaligned Die Strikes – If the dies are not perfectly centered, one above the other, the struck coin will have incorrectly positioned images. Usually the obverse is offset and will look link an off center coin but the reverse will appear normal. These coins do not really command a premium being common from 1%-4% offset. A premium is usually paid for coins more then 5% as this is extreme misalignment. Misaligned dies are common in early 70’s Kennedy half dollars and late 70’s to early 80’s Lincoln cents. With a little luck one can pull these coins out of circulation on a regular basis but finding one that is more then 5% offset is a challenge.
