| double |
A die that has been struck more than one time by a hub in misaligned positions, resulting in doubling of design elements. If shifting occurs in the alignment between a hub and a die, the die will have some of its features doubled. This doubling is then imparted to every coin it strikes. The coins struck from such dies are called doubled-die errors. The 1955 Doubled Die Lincoln cent is one such error.

Seeing 'double' is usually due to an over or underaction of one of the muscles that surround an eye. This does not allow both eyes to point in the same direction. Any sudden appearance of double vision should be investigated by an eye doctor.
