Doubled die is a term in numismatics used to refer to doubling in the design elements of a coin. Doubled dies can appear as an outline of the design or in extreme cases, having legends and dates appear twice in an overlapping fashion.
Doubled die error coins can fetch significant prices when they are noticeable to the naked eye or occur in a popular coin series. One example of this is the 1955 doubled die Lincoln Wheat cent.
Note that the proper terminology for this occurrence includes the letter 'd' at the end of the first word, hence "doubled die". The term "double die" without the first word ending in 'd' is not proper numismatic terminology.

Famous quotes containing the words doubled and/or die:
“What of the heart without her? Nay, poor heart,
Of thee what word remains ere speech be still?
A wayfarer by barren ways and chill,
Steep ways and weary, without her thou art,
Where the long cloud, the long wood’s counterpart,
Sheds doubled darkness up the labouring hill.”
—Dante Gabriel Rossetti (1828–1882)
“To die proudly when it is no longer possible to live proudly. Death freely chosen, death at the right time, brightly and cheerfully accomplished amid children and witnesses: then a real farewell is still possible, as the one who is taking leave is still there; also a real estimate of what one has wished, drawing the sum of one’s life—all in opposition to the wretched and revolting comedy that Christianity has made of the hour of death.”
—Friedrich Nietzsche (1844–1900)
