The Problem
Submitting the Wrong Cards for Grading Is Expensive
Professional grading can cost $20-$150+ per card plus shipping, insurance, and long wait times. If the grade comes back low, your margin disappears fast.
High Costs
PSA charges $20-150+ per card depending on service level. Submit 10 cards and you're looking at $200-1500+ in fees alone.
Long Wait Times
Economy services can take 3-6 months. Express services cost even more. Your money is tied up while you wait.
Risk of Low Grades
A card you thought was a 9 comes back a 6. You've paid for grading on a card that's now worth less than raw.

Testimonials
What Collectors Are Saying
"I was about to submit 20 cards to PSA. PreGradeCards showed me that 8 of them would likely grade below 7. Saved me $400+ in grading fees on cards that weren't worth it."
"The centering analysis alone is worth it. I can now quickly sort through my Pokémon cards and find the ones with the best centering for grading."
"As a dealer, I process hundreds of cards. PreGradeCards helps me quickly identify which cards are worth sending to PSA and which to sell raw. Game changer."
