How do I know if an autograph is real?

Rarely by looking at the signature alone. What separates a genuine piece from a convincing one is an accumulation of evidence: where the item came from, how the ink behaves, whether the paperwork survives being checked, and how the seller reacts to being asked. Any one of those can mislead. Together they are difficult to fake.

1. Start with provenance, not the signature

Where was the item before it reached this seller? A signing event with a date, photographs, and an unbroken chain of custody beats a good story with none of the above, every time. Provenance is the one part of a forgery that cannot be manufactured in an afternoon.

It is also the reason authentication at source is a stronger position than authentication after the fact. Piece of the Past sends staff to the signings themselves, buys nothing in from other dealers, and accepts nothing signed by mail — so the chain of custody starts with someone from the company standing in the room rather than being pieced together later from what a previous owner remembers.

2. Read what the signature itself gives away

Genuine signatures drift. Pressure changes mid-word, letters wobble, speed varies, and the same person signing twice produces two similar but non-identical results. A signature traced or copied from a single template repeats itself exactly, stroke for stroke — consistency that looks like care is often the tell.

Check the pen against the date. A Sharpie signature attributed to 1962 is a problem, because Sharpies date from 1964 onward. Ballpoint on a supposedly 1930s letter has the same difficulty.

Look at how the ink sits. A real signature lies on the surface of a photograph and interrupts the gloss; a printed or facsimile signature is part of the image itself and shows no relief where the pen changed direction. Mechanically produced signatures tend to start and stop at exactly the same points every time and hold an unnaturally even pressure throughout.

3. Check the paperwork, do not just read it

Most issuers maintain live, searchable online registries. Take the serial number from the certificate and search it on the issuer’s own site — typed in by hand, never followed from a link the seller supplies. Piece of the Past’s full letters of authenticity also carry a scannable QR code that opens the registry entry for that specific item, so a phone camera settles the question in seconds.

If the number cannot be looked up, the certificate is decoration rather than documentation. That distinction is worth understanding properly, because it is the single most common place collectors are caught.

4. Then test the seller

Ask for the item flat, in daylight, photographed straight on, with a close-up of the certificate and its number legible. A seller with a genuine piece finds this a mildly tedious request. A seller without one finds reasons.

None of these checks proves a fake on its own. Each is a reason to ask a harder question before money moves.

When to hand it to someone who does this daily

If the piece is valuable, contested, or simply outside your own knowledge, the sensible move is to put it in front of someone who examines this material for a living. For entertainment memorabilia that means a specialist rather than a generalist — someone whose reference points for that particular signer run back decades.

Piece of the Past publishes a phone number and an email address, and its authentication is led by a CEO who wrote the “Fakes, Frauds and Forgeries” column for Autograph Collector along with a price guide that ran to four editions. Asking costs nothing; the wrong purchase does not.
