What Our Users Say
Join thousands of collectors who trust PreGradeCards to make smarter grading decisions.
"PreGradeCards has completely transformed my business. I used to submit hundreds of cards blindly to PSA, wasting thousands on cards that came back as 7s or 8s. Now I pre-screen everything and only submit cards likely to grade 9 or higher. My profit margins have increased by 40%."
"The centering analysis is incredibly accurate. I can now quickly identify which cards have PSA 10 potential without squinting at borders for hours."
"Finally, a tool that understands vintage cards! The corner and edge detection helped me identify hidden flaws I would have missed."
"I use PreGradeCards before listing any high-value raw card. It helps me price accurately and describe condition honestly."
"As someone new to card collecting, this tool taught me what to look for. The detailed breakdowns are educational and helpful."
"Great for bulk screening. I can process my entire inventory quickly and identify the gems worth sending to PSA."
"Love the grade calculator tool! It helped me understand why my cards got the grades they did and what to look for next time."
"ROI positive within my first week. Found 3 cards in my collection that were worth grading that I would have sold raw."
"The AI is remarkably consistent. I've compared results to actual PSA grades on 20+ cards and it's been within half a grade every time."
"Use it at shows to quickly evaluate cards before buying. Has saved me from overpaying for cards with hidden defects."
