Who We Are

A message from our founders

GGS was built around one simple idea: grading should be fast, fair, and treat every collector like they matter — not just the biggest submissions. We turn most orders around in just 3 to 7 days, because we know the wait is the hardest part of sending your cards away. Every submission gets careful, hands-on attention from our team, and if you ever have a question, you'll hear back from a real person, not a ticket number. We built GGS around customer service and value first, so you get an accurate grade, a slab worth displaying, and a team that genuinely cares about getting it right.

Accurate Grading

Every submission is reviewed against a consistent, documented standard, so your grade reflects the true condition of the card — not the mood of the day.

Simple, Quick & Affordable

No confusing tiers, no hidden add-ons. One flat rate, a fast turnaround, and a process built around getting your cards back in your hands quickly.

Designed for Perfection

Housed in a crystal-clear, UV-resistant case with a sharp, minimal navy-and-diamond label — because a card worth grading deserves a slab worth displaying.

Our Mission

To make trustworthy card authentication fast, transparent, and accessible — and to give every graded card a presentation worthy of the collection it belongs to.
