Sitting on a Garage
Full of History?
“My father collected for 40 years. After he passed, I had a garage full of items I couldn't price. Gridiron authenticated 67 pieces and sold 52 of them in three months. The estate check was $28,400.”
“I was hunting a specific Barry Sanders rookie for my son's 16th birthday. Put it on the Want List in January. They called me February 3rd with a PSA 9. Exactly what I needed.”
“As a dealer, I need to know grades are real and COAs are traceable. Gridiron's authentication chain is tighter than anyone I've worked with. I send my clients here.”
