PSA/DNA vs JSA vs Beckett (BAS): Which Autograph Authenticator Should You Use?

A grading company scores a card's condition; an authenticator opines on whether a signature is genuine. Some companies do both under one roof (PSA runs PSA/DNA; Beckett runs BAS), but the two calls are independent — a card can come back a clean PSA 9 with a signature PSA/DNA won't authenticate, or vice versa. See how to tell if a sports card autograph is real for the on-card vs. sticker distinction and forgery tells this guide assumes; this one is about which company to trust with the call.

• Market reputation— the most widely recognized autograph authenticator in sports, riding the same brand trust as PSA card grading. For most signed cards and memorabilia, a PSA/DNA cert is the easiest to resell without a buyer second-guessing it.
• Process— in-person or mail-in submission; genuine signatures get a tamper-evident sticker plus a matching numbered cert card or certificate, both verifiable in PSA's online cert lookup.
• Cost/turnaround— tiered by service level and item value, similar to PSA card grading; bulk/economy tiers run slower during high-volume periods.
• Best for— modern and vintage signed cards, especially anything you plan to resell where broad buyer recognition matters most.

• Market reputation— founded by a former PSA/DNA authenticator and widely treated as the second major name in the hobby, with particular strength on vintage and higher-end memorabilia where exemplar depth matters.
• Process— submission by mail or at hobby shows; a genuine signature gets a numbered JSA sticker and letter of authenticity, cert-lookup verifiable on JSA's site.
• Cost/turnaround— generally comparable to PSA/DNA at similar service tiers; show-day, in-person authentication is a common option for signatures obtained at events.
• Best for— vintage autographs and higher-end memorabilia where a JSA letter carries real weight alongside or in place of PSA/DNA. See What Is JSA Authentication? for JSA's founding, exemplar database, and its 2024 acquisition by Certified Collectibles Group (CCG).

• Market reputation— backed by Beckett's grading pedigree (BGS); strongest where BGS grading itself is strongest — modern cards and autograph cards where a buyer already trusts the Beckett name.
• Process— can run alongside a BGS grading submission so a signed card comes back with both a grade and an authentication sticker/cert in one trip, or as a standalone service for loose autographs and memorabilia.
• Cost/turnaround— bundling authentication with a BGS grading submission is usually cheaper and faster than sending the card to two separate companies.
• Best for— signed cards you're already sending to BGS for grading, where a combined grade-plus-auth submission saves a round trip. See What Is Beckett Authentication Services (BAS)? for BAS's process and combined-submission details.

1. Match the authenticator to the grader, if you're also grading. Sending a card to BGS for grading and Beckett (BAS) for authentication in one submission avoids a second shipping round trip; the same applies pairing PSA grading with PSA/DNA.
2. Check sold comps for that exact player and era — buyer trust in a given authenticator's call varies by sport, era, and even by specific player, especially for signatures obtained outside a manufacturer's licensed on-card program.
3. Confirm the signature is worth authenticating at all — a raw signature on a low-value common rarely recoups the authentication fee; it makes the most sense on cards or memorabilia with real resale value at stake.
4. Verify any existing cert before you pay— all three companies publish an online cert lookup; check the number on the sticker or letter against the seller's listing before assuming it's genuine.
