Frequently Asked Questions

How many cards should I submit at once for grading?+
Most grading companies offer volume discounts starting at 20+ cards. PSA offers price breaks at 20, 50, and 100+ cards. BGS and CGC have similar tiers. The optimal batch size is 20-50 cards — large enough for discounts but small enough to manage risk. Never submit cards just to fill a batch if they have negative ROI.
What is the minimum card value worth grading?+
As a general rule, a card should be worth at least 3-4x the grading cost in its current raw condition to justify grading. For PSA Economy at $20/card, the raw card should be worth at least $60-80. For Express at $100/card, the raw card should be worth $300+. Our calculator shows the exact ROI for each card in your submission.
Should I use PSA, BGS, CGC, or SGC for my submission?+
PSA has the largest market share and highest resale premium for most sports cards. BGS is preferred for modern cards due to subgrades and the coveted Black Label. CGC is the cheapest option and gaining market share. SGC is popular for vintage cards. For bulk submissions of modern sports cards, PSA Economy typically offers the best ROI.
How do I estimate my card condition accurately?+
Use our Condition Grader tool for detailed assessment. For this calculator: 5 = pack fresh (PSA 10 candidate), 4 = near mint (PSA 9), 3 = excellent (PSA 8), 2 = good with minor flaws (PSA 7), 1 = visible wear (PSA 5). Be conservative — most collectors overestimate their card conditions by 1-2 grades.
Can I mix grading companies in one submission?+
No. Each grading company requires a separate submission. However, you can strategically split your cards — send high-end modern cards to PSA for maximum resale, vintage to SGC for their holder style, and budget cards to CGC for the lowest cost. Our calculator helps you compare costs across services.

How Bulk Grading ROI Works

Professional card grading from PSA, BGS, CGC, or SGC adds significant value to sports cards and Pokemon cards — but only if the card is valuable enough to justify the cost. Our bulk calculator analyzes every card in your planned submission individually and as a batch.

For each card, we estimate the likely PSA grade based on your condition assessment, calculate the graded value using real market multipliers, subtract the grading cost, and show you the net profit or loss. Cards marked “SKIP” are costing you money to grade — remove them to improve your batch ROI.

The 3x Rule of Thumb

A card's PSA 10 value should be at least 3x the grading cost for submission to make sense. At $20/card economy pricing, that means the gem mint value should be $60+. This accounts for the risk that not every card will get a 10 — some will come back as 9s or 8s.
