A "Doubled Die" error on a coin is the result of a fault in the die manufacturing process creating either a fully complete image at an angle to the original or, most commonly, what might appear as a blurred image on the coin such as you may get if you move a camera at the point of taking the photo. Such dies should never reach the point of striking a coin.
The term "Doubled Die" should not be confused with the terms "Die Clash", which is the obverse and reverse dies meeting without a blank between them giving a slight mirror image on both sides of the coin, or a "Double Strike" which is the same blank being struck twice by the same dies.

This would mean that a coin could have 2 heads, but one side would be a reverse image of the other side.
