Curved Clip Mint Error Coin: 1978-D Penny

A curved clip mint error coin is a type of numismatic error that occurs during the production of coins. In other words, a 1978-D penny curved clip mint error refers to a portion of the coin’s circumference being absent. This is due to a misalignment during the blanking or cutting process.

1978 penny error

Furthermore, the blanking process involves cutting round metal discs, called planchets from large sheets of metal. Occasionally, the cutting machine may malfunction or experience misalignment. This results in irregularly shaped planchets.  Moreover, the irregularly shaped planchet used to strike a coin, creates a clipped mint error.




Note the Crescent-shaped Indention

Essentially, a curved clip mint error is named because a missing portion of the planchet creates a curved or crescent-shaped indentation. The location and size of the curved clip can vary, but typically affects a small segment of the coin’s circumference.

The Blakesley Effect specifically refers to the raised rim formed along the clipped edge of a coin.  A coin struck with insufficient force or misalignment, displaces the metal pushing it upward.  This causes the formation of a ridge or rim along the clipped area and a flattened area opposite the clip.
