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 Slowpoke ranking
Every Slowpoke card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 13 Slowpoke printings pass. 13 of them (100%) have a gem-rate sample of at least ten graded copies in the population reports, and 9 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 Slowpoke & Psyduck-GX from Unified Minds, gems 41.7% of the time across 3,523 graded copies: +$672 is what a long run of submissions would average, $1,528 is what one lucky copy returns.
The median gem rate across the sampled Slowpoke cards is 30.6%. Roughly one submitted copy in 3 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 13 ranked cards, 5 still cover raw price plus fee at PSA 9, 8 need a 10 to break even and 4 lose money on expectation. 8 rest on a hundred or more graded copies.
Before you submit a Slowpoke 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 Slowpoke card list, or see how gem-mint premiums run across the whole catalogue on the PSA premium index.
