Doubled die also known as hub doubling is a term in numismatics used to refer to a duplication of design elements on a working die created due to a misalignment of the die or hub during the hubbing process. Strength of the doubling can vary from very slight and isolated to extreme and widespread. The exact cause of the doubling can also vary, which is why a class system was created to outline the known and hypothesized causes. Doubled die varieties, when noticeable to the naked eye or occur in a popular coin series, are extremely popular with collectors and can be worth a large premium over the same coin without the doubling. Doubled dies are created when the hub imprints an additional, misaligned image onto a die. The many ways this misalignment of images can occur have been arranged into eight classes. This class system was created when United States mints used a multiple-squeeze hubbing method, meaning the working dies were intentionally hubbed multiple times to transfer a complete image.

Doubled die obverse, or DDO coins are produced by coin dies that are not properly manufactured. The malformed die contains at least one duplicate image, letter, number, or word. Pay special attention to words on the coin and keep a magnifying glass or loupe handy! The Mint uses a stamp called a hub to create coin dies with a CNC milling machine. Several generations of hubs are employed to craft the working dies that strike coins. In the iterations of hubs and die, the image it imprints will be off-center if a hub is not perfectly aligned. If the misaligned die is used to strike coins, the coins it produces will have a doubled image, letter, number, or word. Doubled die obverse coins may have a partial or completely doubled image.

Definition : A doubled die hub doubling is caused by a misalignment or a mismatch between a working hub and a working die. The misalignment or mismatch occurs between a first and subsequent hubbing or sometimes in the course of a single hubbing. Misalignments can occur along three orthogonal planes and three orthogonal axes. Doubled dies that are the result of a misalignment are variously characterized as rotated, offset, pivoted, or tilted. A total of eight classes are recognized. Coins struck from a doubled die will show doubling of the design elements. Doubling can be limited to one element or encompass much of the design.

Many people confuse double die coins with double struck coins. The significant difference is that double-struck coins are hit twice by the same coin die during the striking process. A doubled die coin is produced when the coin die is not manufactured correctly. This manufacturing error leads to the appearance of two images on a single coin die. The more obvious and distinct the error is, the more the coin will be worth. The coin die that strikes double die coins has a partial or fully doubled image. Therefore, the coin has two identical images that are slightly offset. The doubling occurs from mistakes in the die hubbing process.
