Why this guide doesn’t rank them
PSA/DNA, JSA (James Spence Authentication) and Beckett are three of the most widely recognized names in third-party autograph authentication, and collectors also encounter others, such as Piece of the Past and smaller specialists. Experienced collectors have different preferences, and acceptance can vary by area of the hobby, by era and by buyer. CollectorFish doesn’t prefer or promote any provider; on the listing form they appear in alphabetical order.
What these services have in common
- They give an opinion on whether a signature is genuine, based on comparison with known examples and examination of the item.
- They typically record a passing opinion under a certificate number, often with a matching sticker or hologram, that you can look up on the company’s website.
- They usually offer different service levels, for example a quicker opinion and a more detailed letter, at different prices and turnaround times.
- Items can generally be submitted by mail, and some services also review items in person at shows and events.
Services, prices and policies change. Check each company’s own website for current details rather than relying on secondhand summaries.
Opinions can differ
Authentication is expert opinion, not proof. Different authenticators can reach different conclusions about the same item, and any company may revise an opinion. A certificate from any of these companies is information to help you decide, and it doesn’t replace your own due diligence. See autograph authentication explained.
Questions to ask, whichever service you are considering
- What do buyers in my area of collecting usually expect?
- Which service level does this item need, and what will it cost compared with the item’s likely value?
- Does the certificate number on this item look up correctly, and does the record match the item?
- Is the item a type the service has experience with, such as vintage documents, modern sports or entertainment?
