How Doubled Die Coins Are Made
A doubled die coin is one that was casted by a die that was accidentally engraved with a doubled image. A die is the device that imprints an image on blank coins, which are also known as planchets.
Dies are engraved by a positive, or relief, image of the coin called a hub; a hub is created by reducing down the image from an 20cm to 30cm” plaster model.
Sometimes, when a die is created, the hub will accidentally create two images on the coin, which will usually appear as a slight, overlapping misalignment of the same design twice on part of the coin.
Sometimes, the doubling will be quite extreme. In other cases, the doubling is barely noticeable.
How Much Are Doubled Die Coins Worth?
The value of doubled die coins depends greatly on the popularity of a given piece. In many cases, the news media has publicized the discovery of a doubled die. In other situations, a certain doubled die will have a sort of cult following within the greater hobby of coin collecting. In many cases though, a doubled die coin is worth a certain value largely because it made the news and became a well-known and widely desired coin.
