Strike-Through Coin Value: From Grease Fills to Dramatic Impressions
Strike-through error values span the widest range of any error type — from common grease fills worth only a tiny premium to dramatic cloth or wire impressions worth significant amounts. The type of foreign material, the size of the affected area, and whether the material is retained on the coin are the primary value drivers.
What This Means
Strike-through values are driven by how interesting, identifiable, and dramatic the impression is. Common grease fills are too frequent to carry much premium, while identifiable impressions of specific objects are scarce and fascinating to collectors.
What to Look For
- Type of impression — cloth weave, wire, fragment, or grease?
- Size of affected area — larger strike-throughs are more dramatic
- Retained material — foreign object still embedded in the coin?
- Identifiability — can you tell what the object was?
- Denomination — strike-throughs on higher denominations carry more
- Condition — clean surfaces around the strike-through add appeal
Common Mistakes to Avoid
- Overvaluing minor grease-filled die errors that are extremely common
- Confusing environmental damage with genuine strike-through impressions
- Assuming all missing detail is a strike-through — could be weak strike or wear
- Not photographing strike-throughs with proper angled lighting
- Removing retained material that should be left in place
What Affects Value
Strike-through values are driven primarily by the type of impression and its identifiability. A clear cloth weave pattern is worth many times more than a vague grease fill. Retained foreign material on the coin increases value significantly.

Are grease-filled die errors worth money?
Minor grease fills carry very small premiums. Major grease fills where significant design elements are completely missing can carry moderate premiums. The more design that is missing, the more collectible it becomes.
What strike-through types are most valuable?
Cloth strike-throughs (showing clear weave pattern), wire strike-throughs, and retained foreign objects are most valuable. Any strike-through where the object can be identified is significantly more collectible than vague impressions.
How do I photograph a strike-through effectively?
Use strong, angled lighting to create shadows that highlight the impression texture. Multiple angles may be needed to capture the full detail of the strike-through. Good photos are essential for scanning and for potential sale.
Can ErrorHunt detect strike-through errors?
Yes, ErrorHunt's AI scanner can detect surface anomalies associated with strike-through errors. Photograph with good lighting to give the AI the best chance of identifying the impression type.
