Clipped Planchet Error Coins
A clipped planchet happens when the blanking machine punches a blank that overlaps an already-punched area, leaving a coin with a curved, straight, or ragged 'bite' missing from its edge.

What to look for
Types of clipped planchet errors
- Curved clip — Most common — a smooth crescent missing from the edge.
- Straight clip — From the straight end of the metal strip.
- Ragged clip — Irregular tear from the strip's end — scarcer.
- Elliptical clip — Two overlapping punches create an elongated clip.
- Off-Center Strike Error Coins — A related strike error often confused with clips.

Frequently asked questions
How much is a clipped planchet coin worth?
It depends on the size of the clip and the denomination. Small clips on cents bring a few dollars; large or multiple clips, and clips on larger coins, can be worth tens to hundreds of dollars.
How do I know a clip is genuine and not damage?
Genuine clips usually show the Blakesley effect — a weak, flattened rim on the opposite side — and the metal flow looks natural, not cut. Photograph yours in Coin AI to help assess it.
