Read what the document actually asserts
Start with the organization or person issuing the document, the named signer, the item description and the scope of the statement. A shop’s sales receipt, a signing-event certificate and a third-party authentication letter may describe different evidence. Do not treat the acronym as a universal standard or assume an ornate document is more reliable than a plain one.
PSA’s autograph service provides certificate and letter options and describes a replacement process for missing paperwork. Those are examples of one issuer’s workflow, not a rule governing every COA in the hobby. Read the actual issuer’s policy and record before drawing a conclusion about the card in front of you.
Connect the certification to the signed card
Compare the document number, any corresponding identifier on the item, the signer and the description. If the record contains a photograph, compare the signature placement, visible card version and distinguishing details. A letter for a signed photograph does not establish the authenticity of a trading card merely because the player’s name matches.
PSA warns that publicly visible certification numbers can be copied. A successful lookup therefore establishes a record to compare, not automatic physical authenticity. If the card, label, sticker or paperwork appears altered or inconsistent, keep the evidence and ask the issuer or transaction platform for guidance. Do not remove an identifier to inspect what is underneath.
| Check | What should agree | Pause when |
|---|---|---|
| Issuer | Document and official verification site | The source is unclear or impersonated |
| Certification | Readable matching identifiers | Numbers differ or are obscured |
| Description | Signer, object type and relevant card identity | A letter describes another type of object |
| Available image | Actual signature placement and visible copy details | The offered copy differs from the recorded image |
Worked example: a matching name is not enough
Imagine a seller offers a signed card with a letter naming the same athlete. The certification lookup describes an 8-by-10 photograph. That record does not match the object offered, even if both signatures look similar to you. The appropriate next step is to request the correct supporting record, not to rationalize the mismatch as a harmless detail.
In another fictional example, the document describes the correct card but the photograph shows the autograph in a different position. Ask whether the supplied paperwork belongs to a different copy and keep the listing images. Neither example requires you to become a handwriting examiner. It requires you to notice that the evidence does not yet connect the document to this physical item.

- RecordWhat item does the official entry describe?
- ObjectDoes the actual signed card match?
Schematic. Original verification schematic; it does not reproduce certificate security features or authenticate a signature.
Handle older or missing paperwork carefully
An older format should be assessed in its historical context rather than rejected solely for looking different from a new certificate. Use the issuer’s official references and support to ask about the specific document. A seller’s broad claim that all old examples looked this way is weaker than a confirmed issuer record.
For missing PSA paperwork, its autograph service page provides a replacement-request route. Contact the issuer before assuming a downloadable copy or another seller’s letter can substitute. Ask what evidence, fees and item inspection are currently required for your case. Keep an electronic reference copy of your own documents, but do not present a self-made reconstruction as an issuer’s original certificate.
Store the authentication history with the inventory
Give the signed card one inventory ID and link its front, back, paperwork images, purchase record and official verification URL. Record whether you possess the original document or only a reference image. Keep the paper protected separately when necessary, with a clear inventory link, rather than attaching it physically to the card.
When buying or selling, distinguish autograph authentication, autograph condition grading and the card’s own grade. The presence of a COA or LOA does not by itself assign a numerical card grade. Describe exactly what documentation accompanies the item and any unresolved mismatch. A complete record helps the next owner verify the chain instead of having to reconstruct it from a vague authenticated listing title.
Frequently asked questions
Is an LOA automatically stronger than every COA?
No. The issuer, scope, verification evidence and match to the item matter more than the document’s title.
Can a genuine certification number be copied?
Yes. PSA explicitly warns about that risk. Verify the connection to the actual card and paperwork.
Can missing PSA autograph paperwork be replaced?
PSA publishes a replacement-request process. Contact it about the particular certification and current requirements before relying on a replacement.
Does autograph authentication also grade the card?
Not automatically. Read the service scope and any separate card or autograph grade on the record.
