A serialized, tamper-evident sticker applied to every item signed at an official MTP signing event. The unique number on your holo is registered in our database and tied to the specific event and athlete.

Enter the serial number from your holo in the Certification Check above. A match confirms your item was signed at an official MTP event.

check the digits — some numbers are easy to misread. If it still doesn't appear, email admin@morrisontradingpost.com with clear photos of the item and holo and we'll investigate. Not every autographed item we sell came from an MTP signing; some carry third-party certification (PSA/DNA, JSA, Fanatics, etc.) instead.

It's different — and in one important way, stronger. Third-party authenticators give an expert opinion on a signature after the fact. MTP certification means we physically witnessed the signature happen and recorded it. Because we're the direct source, there's no opinion involved. That said, MTP-authenticated items can also be submitted to third-party services if you'd like an additional certification for resale.

Yes. The certification follows the item, not the buyer. Anyone can verify the holo number on this page at any time, which makes MTP-authenticated items easy to resell or trade with confidence.

For select signings, yes — we accept customer send-ins and in-person items when the athlete's agreement allows it. Watch our Upcoming Signings section and social channels for details on each event.

Contact us with photos before removing anything. Because the holo is tamper-evident, removal voids the certification — but if we can match the item and remaining serial digits to our records, we'll work with you on a resolution.
