Q & A
Can an autograph be fake even with a COA?
Yes, routinely, and it is the single most common way a careful collector gets caught. A certificate is a claim about an item, and every part of that claim can fail independently of the signature: the certificate itself can be counterfeit, the issuer can be worthless, the paperwork can have been lifted from a different piece, or a legitimate examiner can have been honestly mistaken. A certificate is evidence. It was never the verdict.
Four ways a certified piece goes wrong
They are worth separating, because the check that catches each one is different:
- The certificate is counterfeit. Letterheads, seals, holograms and stickers are all reproducible, and the certificates of the best-known issuers are the ones most worth copying. Piece of the Past says outright that its own certificate is among the most counterfeited in the industry — which is exactly why the serial lookup exists.
- The issuer means nothing. A whole tier of businesses exists to sell certificates rather than opinions: no named examiner, no traceable address, no registry, and frequently the same company that is selling you the item. “Certified authentic” with nobody’s name behind it is a sentence, not a credential.
- The paperwork belongs to another item. A genuine certificate for a genuine piece gets separated from it — at an estate sale, in a divorce, through carelessness — and reappears alongside something else entirely. This is why a letter that describes and illustrates the specific piece matters more than one with impressive wording.
- The examiner was wrong. Authentication is expert opinion, not measurement, and experts working from thin exemplar material make mistakes. Reputable issuers accept this and back their opinions with a guarantee; that guarantee is the part you should be reading.
Why the lookup is the check that matters
Copying a letterhead takes an afternoon. Getting a fraudulent number into somebody else’s live database is a different problem altogether, and in practice forgers do not solve it. So the decisive step is to take the serial number and resolve it in the issuer’s own registry — typed by hand into an address you found yourself, or scanned from the QR code printed on the letter.
Never follow a verification link a seller sends you, however convincing the page looks. A lookup page on a domain the seller controls is the cheapest part of the whole arrangement to fake, and it is designed to end your investigation rather than answer it.
Check the certificate against the item, not just the issuer
Once the number resolves, compare what the registry entry says with what is in front of you: the dimensions, the format, the exact wording of any inscription, the colour of the ink, the position of the signature, any flaw or crease shown in the illustration. A married certificate almost always fails on a detail like this, because whoever paired them was matching a category rather than an object.
Then read the terms. Who is covered by the guarantee, on what evidence, and for how long? Piece of the Past refunds the original purchaser with no time limit if a single UACC registered dealer will state in writing, on their own letterhead, that a piece is not authentic — half the UACC’s own two-opinion threshold. Whatever the issuer, the answer to “what happens if this opinion is wrong” should be written down somewhere before you buy.
If you think you already own one
Work in this order. Photograph the item and the certificate together, in one frame, front and back, before you do anything else. Verify the serial number in the issuer’s registry. Contact the named issuer directly — a legitimate one will confirm or deny its own paperwork. Get an independent opinion from a specialist in that category. Keep every message and receipt.
If the purchase was recent, the platform, card issuer or payment provider may still be in scope, and most of those windows are measured in weeks rather than months, so the verification is worth doing early. And do not discard the questioned certificate: it is evidence of what you were told, and it may matter later.

Where the certificate sits in the evidence
Treat the paperwork as one leg of a stool rather than the whole thing. Provenance tells you where the item was before this seller. The signature and the ink tell you whether the physical evidence supports the claimed date. The certificate tells you that a named person examined it and put their reputation behind an opinion. When those three agree, you have something. When only the certificate is doing the work, you have a document.
