A profitable PSA 10 can still mean a losing submission.
This teaching example assumes a 20% chance of a $100 PSA 10 and an 80% chance of a $20 PSA 9, with a 13% selling fee. Expected net is (0.20 × $100 + 0.80 × $20) × 0.87 − $10 − $25 = −$3.68. These are illustrative assumptions, not a card recommendation or a current grading quote. Shipping, taxes and other costs would reduce the result further.
Everything you need to flip smarter.
Expected Value Engine
See the modeled expected return on grading any card — not just the PSA 10 dream scenario. Our formula weighs every grade outcome by its historical population share and market value across 69,000+ data points.
Top Cards Rankings
Screen grading candidates by modeled returns. Filter by ROI, EV, gem rate, raw cost, set, language and release year, then verify exact sold comparisons and condition before buying.
Market Trends
Compare changes in tracked raw prices, graded prices, grading volume and sales activity across snapshots. Use the changes to decide where to investigate next.
Low Pop Gems
Find cards with low recorded graded populations. Compare gem rates and price references while checking the exact variant. A low population does not establish demand or profitable resale.
Compare grading companies and tiers
Compare PSA, BGS, CGC, SGC, and TAG across every pricing tier. See which company and service level gives you the best margin on each card. Compare the current costs with the expected outcome for your specific card.
Full Grade Breakdown
Inspect available grade populations and price references to understand the expected-value model. Check disclosed missing prices and remember that population shares are not a prediction for your individual card.
