Best Slaking Cards to Grade
The Slaking 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: Slaking (Power Keepers) at an expected +$368.
Ranked by expected profit 4
| # | Card | Raw | PSA 9 | PSA 10 | Cost | Best case | Gem rate | Expected | Sample |
|---|---|---|---|---|---|---|---|---|---|
| 1 | Expected +$368 per submission: 22% of 227 graded copies came back PSA 10 ($2,000), and a PSA 9 ($94) still clears the $247 you have in it. Confidence high on that sample. | $8 | $94 | $2,000 | $239 | +$1,753 | 22% | +$368 | 227 high |
| 2 | Expected +$275 per submission: 10.5% of 276 graded copies came back PSA 10 ($3,025), and a PSA 9 ($200) still clears the $419 you have in it. Confidence high on that sample. | $20 | $200 | $3,025 | $399 | +$2,606 | 10.5% | +$275 | 276 high |
| 3 | Expected +$181 per submission: 12% of 150 graded copies came back PSA 10 ($2,000), and a PSA 9 ($100) still clears the $256 you have in it. Confidence high on that sample. | $17 | $100 | $2,000 | $239 | +$1,744 | 12% | +$181 | 150 high |
| 4 | Expected loss −$61 per submission: 23.1% of 13 graded copies came back PSA 10 ($100), and only a PSA 10 covers the $87 you have in it — a 9 loses money. Confidence low on that sample. | $6 | $2 | $100 | $81 | +$13 | 23.1% | −$61 | 13 low |
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 Slaking ranking
Every Slaking card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 4 Slaking printings pass. 4 of them (100%) have a gem-rate sample of at least ten graded copies in the population reports, and 3 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 Slaking from Power Keepers, gems 22% of the time across 227 graded copies: +$368 is what a long run of submissions would average, $1,753 is what one lucky copy returns.
The median gem rate across the sampled Slaking cards is 22%. Roughly one submitted copy in 5 came back PSA 10, and most rows here still cover raw price plus fee at PSA 9, so the PSA 9 price does most of the work. Of the 4 ranked cards, 3 still cover raw price plus fee at PSA 9, 1 needs a 10 to break even and 1 loses money on expectation. 3 rest on a hundred or more graded copies.
Before you submit a Slaking 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 Slaking card list, or see how gem-mint premiums run across the whole catalogue on the PSA premium index.
