Autographs 101: How to Avoid Forged Signatures

Autographs are one of the most emotional things to collect — a direct connection to a star, an athlete or a historical figure. Unfortunately, they're also one of the most heavily forged. A little knowledge goes a long way.

Know the non-authentic "real-looking" signatures

Not every fake is a deliberate forgery. Watch for:

• Pre-prints and facsimiles. The signature was printed as part of the photo or card. Tilt the item under light — a real ink signature sits on top of the surface and often shows a slight sheen or indentation.
• Autopen signatures. A machine reproduces a signature, often used by politicians and celebrities for fan mail. Autopen signatures can look unnaturally uniform, with blunt starts and stops and even pressure throughout.
• Secretarial signatures. An assistant signs on the celebrity's behalf. These may look fluent but won't match genuine examples.

A certificate is only as good as its issuer

Many listings come with a "COA" (certificate of authenticity). A COA written by the seller themselves is essentially meaningless. What carries weight in the market is authentication from established third-party services such as PSA/DNA, JSA (James Spence Authentication) and Beckett Authentication Services.

Always verify the certificate or sticker number on the authenticator's website, and make sure the item described matches the one you're buying.

Compare against known exemplars

Signatures change over a lifetime, but they have consistent traits: letter shapes, slant, where the pen lifts, and flourishes. Compare the item with multiple verified examples from the same era. Big differences are a warning sign.

Provenance and photo-matching

The strongest autographs have a documented history:

• Photo-matching — a photo of the celebrity signing that exact item
• In-person signing events run by reputable companies, with holograms and records
• Clear chain of ownership from the original recipient

Grail Hunt tip: Be skeptical of deceased celebrities whose genuine autographs are rare but whose signed photos seem to be everywhere on the market. Scarcity and supply should line up.

Price is a clue

If a signed item from a major star is listed far below market value, there's usually a reason. Genuine autographs from the biggest names rarely sell cheaply.

The bottom line

Understand pre-prints, autopens and secretarial signatures, trust only reputable third-party authenticators, verify every cert number, and favor items with provenance. When in doubt, walk away — there will always be another chance to buy a real one.
