Professional Collectibles Grading
Introducing the GCC Black Gem Grade™
Identify cards that project at GEM MINT level.
GCC Proudly Recognizes Ian Desmond
GCC proudly recognizes Ian Desmond and the submission of the iconic 1979 O-Pee-Chee Wayne Gretzky rookie card as part of his collection review. Alongside this legendary hockey cornerstone, several additional high-value cards were identified and awarded the GCC grading sticker.
“Our experience with GCC Grading delivered exactly the trust and security we'd been searching for but couldn't find anywhere else. Their evaluation and guidance were highly professional, giving us clarity on what we have and how to move forward.”
— Ian Desmond
The finished graded cards reflect GCC's commitment to accuracy, presentation, and collector confidence—featuring clean encapsulation, clear labeling, and a premium look that enhances both display and long-term value.
“The graded cards look amazing, and I would strongly recommend GCC for their exceptional expertise and deep understanding of what collectors truly value.”
