What does ITP mean for autographs?

ITP stands for in-the-presence. PSA's page describes it as getting your autograph witnessed and certified in real time at events, signings or private sessions, with a tamper-evident label issued on the spot.

Can I verify an autograph certificate number online?

PSA's Cert Verification page at psacard.com/cert lets you enter a PSA or PSA/DNA cert number. PSA warns that forgers may counterfeit documents using real numbers, so also compare the sticker and the item.

Is a graded autograph the same as an authenticated one?

No. Beckett's autograph scale grades appearance such as bubbling, fading and cut-off lettering, and PSA lists autograph grading as an add-on to authentication. A grade describes the look of the signature, not whether it is genuine.

Does a certificate prove a signature is real?

No. It records a service's opinion. PSA says verification does not eliminate risk and that it does not view authenticated items listed on the web, so check the paperwork and the item and buy from sellers you can verify.

Autograph Authentication Red Flags: What to Check

2026-11-09 · By CollectorsTrend Editorial · General information, not appraisal, tax, legal or investment advice

A certificate is an opinion, and forgers copy paperwork too. Here is what to ask, what to look up, and what the services say about their own limits.

A signature is easy to copy and hard to prove. That is why serious sellers attach paperwork from a third-party service, and why forgers copy the paperwork too. This guide covers how PSA describes its autograph process, what "witnessed" means, what a certificate can and cannot tell you, and what to ask before you pay. It does not repeat the basics of memorabilia. We read what the services publish on their own pages, and we leave out what we could not load.

What a service says it does

PSA's autograph authentication page describes a process built on examination and documentation. In step one, it says, "PSA authenticators conduct ink analysis, autograph structure analysis, object evaluation and side-by-side comparisons," and "may also use a video spectral comparator to further evaluate the autograph." In step two, "the certified autograph can be verified publicly using our online Certification Verification webpage or mobile application." (The page we read, captured in October 2026, showed two of its four steps.) The page lists the comparator as something examiners "may" use, not a step every item gets.

We tried to read the equivalent pages for JSA and Beckett Authentication Services, and could not load them. We are not describing their processes. Read each service's own page for its method, its fees and its terms before you submit anything or rely on its letter.

Certified versus witnessed

There are two different situations. In the first, a signed item is sent to a service afterward and examined. In the second, the signing is watched. PSA's In-the-Presence page says you can get an autograph "witnessed and certified by PSA" in "real time" at events, signings or private sessions. It lists a "tamper-evident label" "issued on the spot," and says buyers "know your item was signed under expert observation." That is what people mean by ITP, or in-the-presence, authentication.

The difference for you as a buyer: an after-the-fact opinion rests on the examiner's judgment of the ink and the signature, while a witnessed signing adds someone who saw it happen. Neither one is a measurement. And a "witnessed" claim from a seller means little unless the witnessing service issued the label and you can look it up.

Stickers, letters and certificate numbers

Tamper-evident stickers and letters are the paperwork. They are only as good as the lookup behind them. PSA's Cert Verification page, at psacard.com/cert, says it will "verify the validity of PSA & PSA/DNA certification numbers" and lets you "enter a cert number" to search. The same page warns: "Though uncommon, forgers may counterfeit PSA & PSA/DNA documents using certification numbers from public sources." Its note says that verification "does not eliminate risk," that "criminals do attempt to counterfeit PSA grading inserts using actual certification numbers," and that PSA "does not view authenticated items listed on the web." It also says it encourages buying "from trustworthy sources" and that "marketplaces such as Craigslist, Mercari and Offer Up are not recommended."

So a matching number is a first check, not the last. Compare the sticker or letter in the photos to what the lookup page returns, then compare the item in your hands to the item the lookup describes. If a seller sends only a screenshot of a lookup, ask for the lookup link or the number so you can run it yourself. Beckett's grading page says new card labels carry a QR code to "scan to verify your cert instantly at beckett.com," which is for graded cards. Check Beckett's pages for how autograph certificates are verified.

Signature quality is a different question from genuineness

Do not mix up a grade with a verdict. Beckett's published guidelines grade autographs on appearance, and say they are "not rules, only general guidelines." The scale runs from 5 to 10 with no half points. A 10 is "a beautiful, boldly signed autograph that appears nearly perfect to the naked eye." Lower grades describe bubbling, scratching, "yellowing or fading or smearing," and how much of the signature is "hidden (or missing, when referring to a sticker autograph)" or runs "off the card." PSA draws the same line: it lists an add-on to "assign a numerical grade to your PSA-certified autograph," on top of authentication. Those pages tell you how a service describes the look of a signature. They do not tell you whether it is genuine.

They do show what to look at in photos: where the signature sits on the item, whether ink pools or fades unevenly, whether smears or scratches affect letters, and whether any part runs off the edge. Photos that hide the signature area or are tightly cropped are a flag in themselves. Terms like secretarial signatures or autopen machines are widely used in the hobby, but we did not find them defined on the service pages we could read, so we do not define them here.

Questions to ask the seller

Who certified it, and what is the certificate number? Can I run it on the company's lookup page myself?
Was it examined afterward or witnessed at the signing, and who was the witness?
Can I see the sticker, letter or label itself, front and back, not a screenshot of one?
Does the certificate describe this exact item, with the same inscription, item type and any dedication?
What is the return window if the service later disagrees?
Where did you get it, and do you have a receipt, a signing-event record or a photograph of the signing?

The limits

An authentication opinion is a trained person's conclusion from the evidence. It is not proof beyond doubt. PSA's certification page says it does not warrant that an item listed in its database is, in fact, a genuine PSA-authenticated item, which is a statement about the database listing. Fees, insurance, remedies and turnaround are set by each service. Read the terms.

What to do next

Before your next autograph purchase, open the service's lookup page, run the number and write down what it says about the item. Then compare it, line by line, to the listing. If anything differs, ask the seller and wait for a clear answer.
