Clipped Planchet Error Coin - Straight Clip
Australian 1961y 1/2d with straight edge clip and prominent Blakesley Effect
The last entry talked about curved clipped planchet errors. During the manufacturing process coin blanks are punched from a long metal strip. The curved clip coin error occurs when the coin blank is punched from the strip of metal before the hole from the previously punched blank has completely moved away. Another type of clipped planchet coin is the straight edge clip where the coin blank is punched from the strip of metal right at the end of the strip or the edge of the strip. This results in a bite taken from the coin with a largely straight edge. I have seen two types of this error, the so called ragged clip where end of the metal strip has not been cut cleanly and the edge bite has a ragged appearance. A regular straight clip shows a neat straight clip, most likely because the end of the metal strip has been cut and finished properly or the clip overlapped the edge of the strip of metal.
