What does “clipped corner” mean?

What it means

A clipped corner is physical damage to a coin where metal has been removed from one or more edges, specifically at the corners. This is not standard circulation wear; it is an alteration. The metal is shaved, chipped, or worn down to an uneven profile. In numismatics, this is a form of mechanical damage, distinct from environmental toning or surface scratches. The mainstream equivalent is a localized edge defect or physical abrasion, but "clipped corner" is the precise term for this specific type of material loss at the vertex.

What it does to price

Clipping severely reduces numismatic value because it compromises the coin's original planchet integrity. The devaluation is directly proportional to the percentage of metal removed and the visibility of the clip. A minor, barely perceptible nick might reduce value by 10-20% compared to a perfect specimen. A significant clip, where a noticeable chunk is missing, can cause a drop of 50% or more, sometimes rendering the coin non-collectible for high-grade sets. For example, a pristine 1955 Lincoln Cent might sell for $15.00; the same coin with a noticeable clip could sell for $5.00 or less, depending on the severity.

How to spot it

Inspection requires magnification, ideally 10x or higher. The tell is an unnatural, sharp discontinuity on the edge profile at the corner, not a smooth rounding from wear. Examine the coin under direct light to see if the missing metal reveals a different underlying metal grain or if the edge profile is jagged rather than uniform. Sellers might attempt to hide this with poor photography; always request high-resolution, edge-on photos. Common honest mistakes include rough handling during minting or early storage; fakes are rare for clipping itself, but altered coins (where metal was added or smoothed over) are a risk.

Buying smart

Paying a premium for a clipped coin is only justifiable if the coin is otherwise exceptionally rare, and the clip is extremely minor, almost invisible under normal viewing conditions. If the coin is common, the premium is never warranted. A fair deal involves pricing the coin at a significant discount relative to its unclipped counterpart. If a seller lists a clipped coin at 80% of the price of an unclipped version, the discount is insufficient compensation for the damage.

Selling smart

When listing a clipped coin, transparency is mandatory. Do not attempt to hide the defect. Disclose the clip clearly in the description, specifying its location and estimated severity (e.g., "light clip on the upper right corner"). Providing a clear, high-magnification photo focusing directly on the clipped area earns trust and allows the buyer to price the damage themselves, which often leads to a faster, more accurate sale. Omitting this detail leads to disputes and returns.
