When you buy a signed item you did not watch being signed, you are trusting someone's word. Third-party authentication is a way to add an independent opinion to that trust. This guide explains what it is, what the paperwork means and what it cannot do.
What third-party authentication is
Third-party authentication means an independent company, not the seller, reviews an autograph and gives an opinion on whether it is genuine. "Third party" is the key idea: the person who examines the item has no stake in selling it.
Typically the process looks like this:
- Submission. You send the item, or in some cases photos, to the service.
- Examination. Reviewers compare the signature against known examples of the signer's autograph, and look at the ink, the item and other details.
- Opinion. The service decides whether it believes the autograph is genuine.
- Identification. If the item passes, the service marks it, often with a sticker or tag carrying a unique number, and records it in a database.
How each company runs this differs: who reviews, how many opinions are needed, what they examine and what fees apply. Read each company's own description before you decide.
What a COA or LOA is
You will see two abbreviations constantly:
- COA means certificate of authenticity. A document, card or sticker stating that an autograph is genuine.
- LOA means letter of authenticity. A fuller letter that describes the item and states the company's opinion about it.
Both are only as good as the company behind them. A COA from a respected authentication service, linked to a record you can look up, carries weight. A COA the seller printed at home carries none. A certificate should always tell you who issued it, which item it covers and how to verify it.
Some companies collectors know
There are many authentication services. These are a few names you will come across, listed as examples and in no particular order:
- PSA/DNA
- JSA
- Beckett
- AutographCOA (autographcoa.com)
Each has its own process, scope, fees and reputation among collectors and dealers, and acceptance varies by market and by buyer. This is not a ranking or an endorsement of any one company. Before you choose, look at what the company authenticates, how its certificates are checked, how it handles disagreements and what collectors in your area of the hobby say about it.
How to verify a certificate
If an item comes with paperwork, check it:
- Find the number. Most services print a unique certificate number on the sticker, card or letter.
- Look it up on the company's own website. Do not rely on a link supplied by the seller.
- Match the details. The record should describe the same signer and the same kind of item. A record for a photo does not prove a baseball.
- Compare the images, where the service shows them. Make sure the item in your hands matches the one in the record.
- Be careful with fake stickers. A real sticker can be moved, and a fake one can be printed. A record that matches the item is the better evidence.
What authentication can tell you
- That an independent reviewer examined the item and formed an opinion
- That the item has been recorded, so it can be identified later
- A degree of added comfort when you are buying or selling, especially for higher-value pieces
What authentication cannot tell you
This part is important.
- It is an opinion, not a guarantee. Reviewers can be wrong, and different companies sometimes disagree. Authentication reduces risk. It does not remove it.
- It is not an appraisal. It does not say what an item is worth.
- It usually does not prove when or where something was signed, or that the signer signed it for any particular occasion, unless the company says so and documents it.
- It does not cover the whole item. A letter might address the signature, not whether a jersey, ball or photo is itself period-correct or in good condition.
- It does not last by magic. Stickers can fall off, and paperwork can be lost. Keep records in more than one place.
Authentication companies themselves state that their results are opinions. Read their terms to see what they promise, what they do not and what happens if they change their opinion later.
When authentication is worth it
Authentication costs money and time, so it helps to be selective.
- For high-value pieces, where an extra opinion is cheap relative to the risk.
- For items you did not see signed, especially from signers with many known forgeries.
- Before you resell, since buyers often look for recognized third-party paperwork.
- When the signature is unusual, and you want a more experienced eye.
It may be less useful for items you obtained and can document yourself, such as something you got signed in person or through the mail, and for inexpensive pieces where the fee would exceed the value. A photo of the signing, the date and the place can be a good record on its own.
Authentication and buying from sellers
A trustworthy seller with a clear return policy and a record of happy customers is part of the picture, not a replacement for authentication and not made unnecessary by it. The best combination is a seller you trust, an item you have compared against known examples and, for pieces that matter, an independent opinion.

A note about AutographCOA
AutographCOA provides authentication with a public certificate lookup, so you can check a certificate number yourself at autographcoa.com. As with any service, read how it works and what its certificates mean before you submit an item.
Questions to ask before you submit anything
- What exactly will the company examine, and what will its paperwork say?
- What does it cost, including shipping and insurance both ways?
- How long does it take?
- What happens if the item does not pass?
- Can anyone verify the result later, and how?
- What are the terms if there is damage or loss?
A few minutes of reading will tell you whether a service fits what you want.
