How to Spot Fake Autographs
Counterfeit autographs are everywhere. Learn the red flags that separate real signatures from forgeries, autopens, and secretarial signs.
6 Red Flags of Fake Autographs
Autopens & Stamp Signatures
Machine-produced signatures look too perfect. Every line is identical across copies. Look for slight variations that indicate a human hand — real autographs are never exactly the same twice.
Pre-prints & Printed Signatures
Some items feature signatures printed directly onto the surface. Run your finger across the autograph — real ink sits slightly above the surface, while printed signatures feel perfectly flat.
Secretarial Signatures
Assistants often sign on behalf of celebrities and athletes. These signatures may look passable but typically lack the flow, pressure variation, and personality of authentic autographs.
Inconsistent Ink Flow
Forgers often pause, hesitate, or retrace. Look for unnatural ink pooling, shaky lines, or pen lifts in the middle of strokes where a genuine signer would have smooth, confident motion.
Too-Good-to-Be-True Pricing
If a signed Michael Jordan jersey is $50, it's almost certainly fake. Research fair market values on PSA, Beckett, or recent auction results before purchasing.
No Provenance or COA
Reputable sellers provide certificates of authenticity from recognized authenticators (PSA, JSA, Beckett). A generic or self-issued COA has no real value.
Quick Authentication Checklist
Does the signature match known exemplars from authentication databases?
Is there natural pen pressure variation (thick and thin strokes)?
Can you feel the ink sitting above the surface of the item?
Does it come with a COA from PSA, JSA, or Beckett?
Is the price consistent with fair market value for this signer?
Was the item obtained from a reputable source with provenance?
