What is a clipped planchet error?
How clipped planchets form
A planchet is the blank metal disc that is struck to make a coin. Blanks are often punched out of a strip of metal, and if the punch overlaps a spot already removed, a piece is missing from the blank. The coin is then struck with a clipped edge, which shows as a curved or straight missing section.
Clips can be small or large, and a larger clip is usually more noticeable and more desirable to collectors. The missing area is usually smooth, and the rim near the clip may look flattened.
- Missing piece from the blank before striking
- Curved or straight edge shapes are common
- Larger clips are usually more noticeable
- Affects coins of many types and metals
Checking your coin
Look at the edge and rim with a magnifier. A clip will show a clean edge where metal is missing, with the design possibly cut off near the spot. Compare with a normal coin to see the difference in roundness and rim thickness.
Make sure the missing piece is not from damage or wear. Impact damage often looks rough and irregular, while a clip is generally smooth. A coin shop or grading service can confirm what you have.
Common mistakes
- Confusing a clipped planchet with a coin that has been bent or damaged after striking.
- Trimming or filing a coin to make it look like a clip, which lowers its value.
