How it works
Four steps to a certified slab
From your collection to a tamper-evident, population-tracked MAS slab — fast, secure, and fully verifiable online.
01
Submit
Start an online submission, choose your service tier, and log each card's details. Add optional autograph services per card.
02
Receive & Log
Our team receives your package, logs every card into the MAS system, and confirms it against your submission.
03
Grade & Encapsulate
Certified experts assess centering, corners, edges, and surface under controlled light, then seal each card in a tamper-evident holder.
04
Certify & Return
A unique cert number and live population entry are issued, and your graded slab ships safely back to you.
