Why You Should Authenticate Sports Autographs Before Selling
Introduction
In the world of sports memorabilia, autographs can be among the most valuable and vulnerable collectibles. Whether you’re a seasoned collector or simply looking to sell a few pieces, having your autographs authenticated by a respected third-party expert is essential before offering them for sale.
Why Authentication Matters
The sports autograph market has long been plagued by forgeries. From legends like Babe Ruth and Michael Jordan to modern stars like Tom Brady or Shohei Ohtani, counterfeit signatures are rampant.
Without third-party verification, even genuine autographs may be viewed with suspicion by buyers, auction houses, and dealers. Most autographs, even attained first hand, will be looked at with suspicion by a potential buyer. It is built in to the dynamic of autograph transactions. Owner/Sellers should not take it as an attack on their trustworthiness. I have visited collectors to conduct appraisals and many autographs are not authenticated. Many believe the autographs the will never be sold and will remain in the family. Spoiler…some family member down the line will want to sell that autograph and it will be so much smoother with an authentication.

Trust Builds Value
Authentication provides trust, which is the cornerstone of any successful sale. A certificate or letter from a top-tier third-party authenticator tells potential buyers that:
The autograph has been evaluated by experienced professionals
Industry-standard techniques were used to confirm its legitimacy
The item is safe to purchase with confidence
With proper authentication:
Buyers are more confident, which often leads to faster, higher offers
Marketplaces take you seriously—many won’t list unverified items
Value is protected—authenticated pieces typically sell for much more
Selling Without Authentication? A Risky Move
If you skip authentication, you might:
Be forced to accept lower offers
Be rejected or restricted from major platforms (e.g., eBay, auction houses)
Face refunds, reputation damage, or even legal issues if authenticity is disputed
Who are the Authenticators?
Stick with industry-respected companies, including:
PSA/DNA – A leading name in sports and celebrity autograph authentication
JSA (James Spence Authentication) – Known for signature accuracy and reliability
Beckett Authentication Services (BAS) – Rapidly growing, highly trusted
Do your research and choose an authenticator with a solid reputation and transparent process.
Final Thoughts
Authentication is more than just a certificate—it’s a way to safeguard your credibility and maximize your return. For a relatively small cost, you gain peace of mind and increase the likelihood of a successful sale.
Whether it’s a single signed item, or an entire collection of Hall of Fame memorabilia, authentication is a smart, necessary investment.
