One thing to note on the value of broadstrikes error coins – very wide and well centered pieces will bring much higher prices than the estimates below. Also, if the coin normally has a reeded edge, it will be missing from a broadstruck coin. Without the retaining collar, the coins spread out and become larger than normal coins. If the collar becomes jammed within the press, a partial collar error may occur in which some portion of the coin’s edge is properly formed, while another portion is broadstruck. This results in a coin struck outside the retaining collar. Sometimes the plating is partially or completely missing, resulting in cents with a silvery looking surface on part or all of the coin.īroadstrikes are common coin error, and they’re the result of the collar jamming or otherwise failing to enclose the planchet. Zinc cents with copper plating have been minted since the middle of 1982. In the case of clad coins, the outer layer may be completely or partially missing on one or both sides. Lamination errors may be missing or attached to the coin’s surface. These coin errors can be caused by dirt or gas trapped in the strip as it is rolled out to the prescribed thickness. Type one flans have flat edges, type II flans have raised rims, ready for the coinage press.Ī lamination error occurs when a coin has a fragment of metal missing or peeled off the coin’s surface. The value of error coins with cracks and cuds depends on the size and placement of the die break. The planchet metal then fills this void, and the resulting coins shows a featureless blob where the die broke.Ĭracks appear as raised irregular or jagged lines at the crack’s location, and can distort legends and other parts of the coin’s design. As these cracks deepen and reach from one edge of the die face to another, that portion defined by the crack may actually fall away from the die. The repeated stress of striking planchets causes dies to wear down and, in some instances, crack. These occur when a portion of the die breaks away as the consequence of a progressive crack. Major die breaks, commonly known as “cuds”, are perhaps the most popular die errors. Generally the more severe and interesting the error the more valuable the coin. Clips are categorized as curved, straight, ragged, incomplete and elliptical.
Values of clipped planchets may vary depending on the coin, the type of clip and the percentage missing from what would be a normal coin.
When the planchet punching press does not advance the metal coinage strip properly, the resulting strokes may overlap previously punched out metal and produce planchets that are incomplete, or “clipped”.
