Global Card Grading
About Global Card Grading
Built by collectors, for collectors
Global Card Grading (GCG) was created with one clear goal: to deliver a reliable, transparent, and consistent card grading experience collectors can trust.
From day one, we set out to build a grading service that removes guesswork. Every card we grade is documented with full, high-resolution images, including centering, corners, edges, and surface scans. We believe collectors deserve to see exactly how a grade was determined—not just the final number.
Consistency Through Standards and Technology
At GCG, every card is evaluated using a defined grading standard followed by all graders. This framework is reinforced with AI-assisted grading tools to help ensure consistency across submissions. Our technology supports precise analysis of centering, corners, edges, and surface condition, helping reduce subjectivity and variation.
By publishing and following a clear grading standard, we allow collectors to understand what to look for and what to expect—before a card is ever submitted.
Transparency You Can See
Transparency is a core principle of our company. Each graded card includes:
- Detailed image documentation
- Clear breakdowns of grading criteria
- Visual evidence supporting the final grade
Our goal is simple: collectors should be able to review the data and understand the result with confidence.
Fast Turnaround, Fair Pricing
We prioritize fast turnaround times without compromising accuracy or quality. Our pricing is based strictly on the service level and turnaround time, never on the value of the card. Whether your card is worth $10 or $10,000, you pay for the work we perform—not its market price.
Built for Collectors
Global Card Grading is built by collectors, for collectors. We focus on consistency, speed, and full transparency—so you always know what you're getting and why.
