So you’ve found a signed jersey online, or maybe you’re eyeing a baseball at a local shop. It looks real, it feels special — but is it? One of the most important things to understand as a collector is the difference between authenticated and non-authenticated memorabilia. It can mean the difference between a treasured piece and an expensive mistake.
What Does “Authenticated” Mean?
Authenticated memorabilia has been reviewed and verified by a professional third-party company whose job is to confirm that a signature or item is genuine. These companies use expert handwriting analysis, witness programs, and tamper-proof holograms or certificates to back up their opinion.
Some of the most trusted names in authentication include:
• PSA/DNA (Professional Sports Authenticator)
• JSA (James Spence Authentication)
• Beckett Authentication Services (BAS)
• Fanatics Authentic
When a piece is authenticated, it typically comes with a certificate of authenticity (COA) and a hologram sticker that ties the item to a record in the authenticator’s database. You can verify it online.
What About Non-Authenticated Items?
Non-authenticated memorabilia simply hasn’t gone through that third-party verification process. That doesn’t automatically mean it’s fake — but there’s no independent expert backing up the claim that it’s real. These items might come with a seller-issued COA, but that’s worth very little since anyone can print one.

Tips for Buyers
• Always look for third-party authentication — not just a seller-issued COA. A COA from PSA, JSA, or BAS carries real weight.
• Verify the hologram. Most top authenticators let you look up the item number on their website. If it doesn’t appear, walk away.
• Be cautious of deals that seem too good to be true. A signed LeBron James jersey for $30 is almost certainly a fake.
• If you buy non-authenticated, consider submitting it for authentication yourself. It can dramatically increase the item’s value and your confidence in it.
• Buy from reputable sellers. Established auction houses, licensed dealers, and official team stores are safer bets than random online listings.
Bottom Line
Authenticated items cost more for a reason — they come with confidence. If you’re collecting for investment or resale, authentication is essentially non-negotiable. If you’re buying something purely for personal enjoyment and you trust the source, non-authenticated items can still hold sentimental value. Just go in with eyes open, and never let excitement override caution.
Happy collecting!
