Collecting Clipped Planchet Error Coins

indentError collectors usually end up collecting different types of clip error coins. Clip errors are coins struck on a clipped planchet. This happens when a blank is incorrectly punched from a sheet of metal. There are various types of clips as well as other error coins that have a clip involved. The larger clips are preferred and priced accordingly.

indentRegular coin collectors under appreciate clips. Some think they can easily be faked, which is not true. There are diagnostics for real clips, such as metal flow and the Blakesley Effect. Metal flow is metal movement towards the clip. The pressure from the dies wants to push metal towards the blank space left by the clip. Blakesley Effect happens near the rim and is characterized by weakness in the strike opposite the clip. Some numismatics think all real clips will have the Blakesley Effect, but that is not the case. Some genuine clips do not show that characteristic. Metal flow seems to be a constant on real clips so it is what I use as a diagnostic to confirm true clips.

indentThe percentage of a clip error is determined by weight. There are many different types of clip errors. The most common clip is the curved clip followed by the straight clip which happens at the end of the sheet of metal. There can be double, triple, and multiple clipped coins. Rarer clips include ragged, bowtie, and crescent clips. Another very rare error is the incomplete clip. Sometimes a clip can be part of a multiple error coin like an off center on clipped planchet. I even have examples of a clipped planchet struck thru another coin.

indentClips may be one of the only major errors found on coins minted from 2002 until present. In 2002 the US Mint put in policies and machinery to try to eliminate error coins from getting out. Clip errors seem to slip through the mints efforts and may be the only way to get a major error on certain issues.

indentThere is a lot more to a collection of clip error coins than most numismatics think. It is quite a fascinating sub-field of error collecting with all the different types of clips and coins with multiple errors that include clips as part of the error.
