Ranked by expected profit 3
| # | Card | Raw | PSA 9 | PSA 10 | Cost | Best case | Gem rate | Expected | Sample |
|---|---|---|---|---|---|---|---|---|---|
| 1 | Expected loss −$44 per submission: 3.8% of 26 graded copies came back PSA 10 ($225), and a PSA 9 ($90) still clears the $89 you have in it. Confidence low on that sample. | $17 | $90 | $225 | $72 | +$136 | 3.8% | −$44 | 26 low |
| 2 | Expected loss −$58 per submission: 3.8% of 186 graded copies came back PSA 10 ($199), and only a PSA 10 covers the $97 you have in it — a 9 loses money. Confidence high on that sample. | $25 | $80 | $199 | $72 | +$102 | 3.8% | −$58 | 186 high |
| 3 | Expected loss −$61 per submission: 0% of 32 graded copies came back PSA 10 ($116), and only a PSA 10 covers the $88 you have in it — a 9 loses money. Confidence medium on that sample. | $17 | $47 | $116 | $71 | +$28 | 0% | −$61 | 32 medium |
Expected = every grade outcome weighted by its share of the card's graded population, minus the raw price and the grading cost (PSA tier fee for the graded value plus ~$20 round-trip shipping, fees as of 2026-08-26). Best case is the PSA 10 leg alone. Gem rates come from a self-selected population — collectors grade their cleanest copies — so read them as an upper bound. Raw is a blended market price, not a sale of your copy. Full method and filters on the grading index.
