Authentication is only as strong as the authority behind it. That's why we match each category to the most respected name in that field — Beckett and James Spence for signed music and entertainment, PSA/DNA for collectibles, Zarelli for space artifacts, OneCOA and NFC for designer figures. No shortcuts. No second-tier services. The right authenticator for the right piece, every time.
The Second Layer
How Gauntlet Gallery Authenticates
The industry's top authentication bodies do their job. Then we do ours. Every piece in our catalog passes an independent Gauntlet review — on top of whatever third-party certification it already carries.
1
Third Party First
Third-party cert is the baseline, not the finish line
Every piece must carry Beckett, JSA, PSA, Zarelli, or OneCOA documentation matched to its category. That certificate is the starting point — our review is what happens next.
2
Independent Review
We examine every piece ourselves — independently
Our team reviews provenance, substrate, signature, and condition independent of the third-party cert. Anything inconsistent stops the piece from moving forward.
3
Two Outcomes Only
Pass or reject. No gray area, no exceptions
A piece meets our standard or goes back to the seller — no caveats, no grading on a curve. What you see here passed.
4
Permanent Record
A blockchain certificate that can't be altered — by anyone
Passing pieces receive a TrueCOA minted on Polygon — unique serial, full provenance, high-res photos. Verify anytime at truecoa.com.
Full Authenticity Guarantee
If you ever receive a piece you believe to be inauthentic, we conduct a full re-examination alongside a qualified third-party authenticator — and guarantee complete compensation if it fails the authentication criteria on which it was sold. No runaround. No fine print.
We only work with the best.
