If you’re buying a signed piece of memorabilia, the authentication behind it matters as much as the signature itself. The three services you’ll see most often are PSA/DNA, Beckett Authentication (BAS), and James Spence Authentication (JSA). All three are respected throughout the industry; all three use tamper-evident labels, expert analysis, and online verification databases; and all three add long-term value to the items they certify.
But they’re not identical. Each has a different history, a different process, and a different standing in the marketplace. This guide breaks down how each one works so you can understand exactly what you’re getting when you see their name on a piece of memorabilia.
PSA/DNA — The Industry Standard
PSA (Professional Sports Authenticator) is the largest and most widely recognized authentication service in the world, with over 35 million collectibles certified. Their autograph authentication division, PSA/DNA, has been operating since the late 1990s and uses a multi-step process that includes ink analysis, autograph structure analysis, side-by-side comparison against known exemplars, and when necessary, examination with a Video Spectral Comparator (VSC). Every autograph is reviewed by at least three separate experts before a determination is made.
When an autograph passes authentication, PSA/DNA applies a tamper-evident holographic sticker containing a unique certification number and a synthetic DNA marker. The DNA tagging adds a layer of security that is virtually impossible to replicate; PSA states the odds of randomly reproducing their specific DNA sequence are one in 33 trillion. Every cert number is permanently verifiable in their online database at psacard.com.
As of October 2023, PSA/DNA transitioned away from issuing physical certification cards with standard submissions. Authentication now consists of the tamper-evident holographic sticker plus a permanent digital Certificate of Authenticity (COA) in their online database. Items submitted at $50 and above automatically receive a full Premium Letter of Authenticity; items below that threshold can be upgraded for an additional $15. Older PSA/DNA items may still have the original 3×3 physical certification card; both formats are equally valid.
PSA/DNA remains the gold standard in the hobby. Their cert numbers are the most widely recognized by collectors, dealers, and auction houses worldwide. When collectors evaluate a signed item, PSA/DNA authentication consistently carries the highest level of trust and typically commands the strongest secondary market confidence of any authentication service. For most collectors; if you see PSA/DNA on an item, that is the benchmark.
Beckett Authentication (BAS) — Deep Expertise, Strong Reputation
Beckett Authentication Services (BAS) is the autograph division of Beckett Media, a name that has been synonymous with sports and entertainment collecting for decades through their grading services and price guides. Founded by Dr. James Beckett in 1984, Beckett became one of the most recognizable brands in the hobby through its monthly price guides before expanding into grading and authentication. In December 2025, Beckett was acquired by Collectors; the parent company of PSA. Beckett continues to operate as an independent brand with its own operations, grading standards, and authentication team. Their authenticators bring a combined 100 years of experience and certified over 2 million items in 2024 alone.
The BAS process is similar to PSA/DNA in its fundamentals. Experts analyze ink, structure, and exemplar comparisons; advanced tools like Pro-Scope and VSC machines are available for closer inspection. When an autograph is deemed authentic, a half-inch oval tamper-evident label with a unique BAS certification number is applied to the item. This label is designed to leave behind fragments if removed; preventing it from being transferred to a different item. Collectors can verify any cert number instantly at beckett-authentication.com.
Beckett also offers Letters of Authenticity (LOA) for an additional fee on lower-tier submissions; items authenticated at $50 and above automatically receive a full LOA. They offer encapsulation for trading cards, baseballs, and flat items like cuts and index cards; and their Card & Auto Grade service combines card grading with autograph authentication in a single slab.
BAS carries strong recognition and respect across the hobby. Their authentication is accepted by every major auction house and dealer network. For collectors who already work within the Beckett ecosystem for card grading, BAS authentication offers a natural complement. Beckett-authenticated items hold their value well and are trusted by serious collectors.
JSA — The Authenticator’s Authenticator
James Spence Authentication (JSA) was founded in 2005 by James Spence, Jr.; a figure with over 30 years of hands-on autograph authentication experience. Spence built his reputation authenticating for every major auction house in the country before launching JSA; and the company has since grown into one of the most respected names in the field. JSA now operates out of two locations in Fort Lauderdale, Florida and Parsippany, New Jersey; and has built an exemplar database of nearly 500,000 files.
JSA was acquired by Certified Collectibles Group (CCG); the parent company of NGC (coins) and CGC (comics). This partnership has expanded JSA’s capabilities; including a co-branded CGC x JSA service that combines card grading with autograph authentication. JSA operates out of events nationwide and offers both quick-turn hologram-only authentication and full Letters of Authenticity.
JSA’s reputation is built on the personal expertise of its founding team and their deep relationships with the auction and dealer community. Their COAs and LOAs are accepted universally. JSA-authenticated items carry strong collector confidence and hold long-term value in the marketplace.
So Which One Should You Trust?
All three. That is the honest answer. PSA/DNA, Beckett, and JSA are all legitimate; industry-respected authentication services that add real, lasting value to any signed item they certify. An autograph authenticated by any of these three carries more collector confidence than an unauthenticated signature ever will; regardless of who signed it.
That said; PSA/DNA remains the most widely recognized and trusted name in autograph authentication. Their cert numbers are the most universally accepted across the hobby; they have the largest database of certified items; and PSA/DNA authentication consistently carries the strongest buyer confidence in the marketplace. When most collectors see a PSA/DNA hologram and cert number on an item; that is the standard they measure everything else against.
Beckett and JSA are both excellent services with strong reputations and deep expertise. Neither is a lesser choice. But if you are looking at two identical items and one carries PSA/DNA authentication; that is the one most collectors will gravitate toward first.
How to Verify Any Authentication
No matter which service authenticated your item; verification takes less than 30 seconds. Enter the cert number from the tamper-evident label into the appropriate online database and confirm the item matches what is on file.

If you cannot verify a cert number online; do not buy the item until you can confirm it directly with the authentication company.
