Doubled dies, off-center strikes, die cracks and cuds, clipped planchets, wrong-planchet errors, broadstrikes, partial collar strikes, lamination errors, rotated dies, missing design elements, and many other anomalies. Every major U.S. error type is covered, plus errors on coins from over 50 countries.
Error category classification, confidence score for each finding, side-by-side comparison with known reference patterns, and a rough value estimate when the variety is in our database. No payment required for the first scans.

The AI flags potential errors with high accuracy but no automated system is 100% perfect. Significant findings should always be confirmed by a professional grading service like PCGS or NGC.
A smartphone or camera capable of taking a clear, focused photo. Good lighting helps. No special equipment is needed.
