In order to quality as an off-center, there must be design missing on at least one side of the coin, and it also must be struck out of collar (no reeding on the edge except perhaps minor traces.) Diagnostics include It is copper as well, which is different from a nickel's normal metal.Īn off-center is a coin which has its design struck off of the planchet. The above coin is a Jefferson nickel struck on a Lincoln cent planchet. The result was a planchet which has a ragged clip.Īn off-metal is a coin struck on a planchet other than what it was intended to be struck on, but also is a planchet which is a different metal than what the coin is normally struck on. The shape comes from the end of a coil of planchet strip which had not had it's rough, ragged end cut off, but instead was sent straight into the blank press. Then the planchet strip is not advanced forward all the way, resulting in the blanking press punching out planchets which overlapped the previously only partially punched out planchets, leaving an arching line across both sides of the coin.Ī ragged clip is a coin with a rough, ragged clip area. This error occurs when the blanking press does not punch all the way through the planchet strip, and then retracts. ![]() The error is a close relation to the incomplete clip, but is different in that when it punches the previously partially punched planchets, it punches them out all the way resulting in an overlap that produces an elliptically shapped planchet. A very rare error type.Īn elliptical clip is a coin which is struck on a oval or elliptically clipped planchet. If the blanking dies overlap one of the corners of the planchet strip, the result will be an outside corner clip. The punched out planchet will have a straight edged clip, call a straight clip. So for example, you might see a small dimple of metal missing on the rim, but this type of mint error coins would still be perfectly "round." On a clad coin, you will see a visible "shift" in the layers of metal on the edge where the disc clip is, but the coin will still be completely round.Ī straight clip occurs when the blanking dies punch planchets out of the planchet strip in such a way that they overlap one of the edges of the planchet strip. This clip is defined as being a clip so small, it can only be seen on the rim or in the "shift" of metal on the edge, but which does not effect the coin's diameter in any way. This results in coins with curved areas of metal missing called a curved clip. We will continue to add to this list over time, so check back often! mint errors examplesĪ curved clip occurs when the sheet of planchet strip is not advanced forwards far enough after having blanks punched out, causing the blanking dies to overlap the previously punched out holes. Of course, the list is not exhaustive, but it includes many different types. ![]() Although there are many ways in which a coin can have an "error", the errors all have definitions (although, new mint error types are discovered form time to time, particularly as the Mint's equipment changes!)īelow, you will see a partial list of some of the mint error types commonly encountered. Mint's are factories, and like all factories, the machinery breaks, people make mistakes, and all of it can result in improperly minted coins. Mint error coins can occur in many different ways, and come in all shapes, sizes, and with countless combinations and variations.
