Accurate, affordable grading matched with a world-class slab design — so your cards are protected, verified, and ready to display.

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.
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.
Grading Overview
Engineered for perfection
Clear fees, realistic timelines, and a scale built around what actually matters: the condition of your card.
The GGS Scale
To optimize value, we only encapsulate Mint 9 and above
All other cards incur the small review fee noted above instead of a full encapsulation.
