Who We Are

A Grading Company That Actually Gets It

King Authentications was built by collectors, for collectors. We know how much your cards mean to you — and we believe every submission deserves to be treated with the same care and passion you put into building your collection.

We started King Authentications because collectors deserve the best — fast turnarounds, accurate grades, and every card handled with the care it deserves from the moment it arrives.

Every card that comes through our doors is treated like it belongs to us. Because we know it matters to you — and that's enough reason for us to care.

What Drives Us

Our Core Values

Speed Without Compromise

We built King Authentications around one promise: your cards back fast. Same-day and next-day turnarounds mean you never wait weeks or even months to hold your graded collection.

Honest Grading

Every card is graded against a strict 1–10 scale with no bias. We grade what we see — corners, edges, surface, and centering — and stand behind every label we put on a slab.

Collector-First Mindset

We're collectors ourselves. We know how much these cards mean, which is why we handle every submission with the same care we'd give our own collection.

Professional Encapsulation

Each graded card is sealed in a tamper-evident, UV-resistant slab that protects your investment and displays beautifully in any collection.

Why Collectors Trust Us

Your Cards Deserve Better Than a 6-Week Wait

We started King Authentications because the hobby deserved a grading option that moves at the speed collectors actually need. No gimmicks, no inflated grades — just honest, fast, professional grading from people who love the hobby as much as you do.
