Best Keldeo Cards to Grade
The Keldeo cards worth grading, ranked by expected profit per submission — every grade outcome weighted by how often the card actually receives it — after current grading fees. The PSA 10 best case is shown on every row but does not decide the order. Top pick: Keldeo (XY Black Star Promos) at an expected +$395.
Ranked by expected profit 6

|---|---|---|---|---|---|---|---|---|---|
| 1 | Expected +$395 per submission: 3.3% of 399 graded copies came back PSA 10 ($14,000), and a PSA 9 ($235) still clears the $1,179 you have in it. Confidence high on that sample. | $20 | $235 | $14,000 | $1,159 | +$12,821 | 3.3% | +$395 | 399 high |

| 3 | Expected +$41 per submission: 40.9% of 274 graded copies came back PSA 10 ($285), and only a PSA 10 covers the $95 you have in it — a 9 loses money. Confidence high on that sample. | $12 | $35 | $285 | $83 | +$190 | 40.9% | +$41 | 274 high |

| 6 | Expected loss −$18 per submission: 52.2% of 4,419 graded copies came back PSA 10 ($203), and only a PSA 10 covers the $152 you have in it — a 9 loses money. Confidence high on that sample. | $70 | $59 | $203 | $82 | +$50 | 52.2% | −$18 | 4,419 high |
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 2026-09-26). 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.
How to read the Keldeo ranking
Every Keldeo card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 6 Keldeo printings pass. 6 of them (100%) have a gem-rate sample of at least ten graded copies in the population reports, and 5 of those keep a positive expected value once every grade outcome is weighted by how often the card actually receives it.
The order is expected profit, not the PSA 10 best case, which rewards the widest raw-to-gem gap whether the card gems one time in two or one in fifty. Here the top row, the Keldeo from XY Black Star Promos, gems 3.3% of the time across 399 graded copies: +$395 is what a long run of submissions would average, $12,821 is what one lucky copy returns.
The median gem rate across the sampled Keldeo cards is 40.9%. Roughly one submitted copy in 2 came back PSA 10, and most rows here need that PSA 10 to cover raw price plus fee, so the gem rate decides whether a submission pays. Of the 6 ranked cards, 2 still cover raw price plus fee at PSA 9, 4 need a 10 to break even and 1 loses money on expectation. 5 rest on a hundred or more graded copies.
Before you submit a Keldeo card
Grading pays on condition. The four things every grader scores — centering, corners, edges and surface — can be checked at home before paying a fee, and a copy that is visibly off-centre or has a whitened corner will not gem whatever the population says. Those gem rates come from a self-selected population of clean copies, so a random copy does worse.
The cost column assumes a PSA submission at the tier covering the card's PSA 10 value, fees as of 2026-09-26, and raw is CardTrack's blended near-mint price, not a sale of your copy: pay more, or hold a lighter copy, and the break-even moves against you. Test a card with your own numbers in the ROI calculator, see the printings that fail the bar on the Keldeo card list, or see how gem-mint premiums run across the whole catalogue on the PSA premium index.
