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 Gym Challenge ranking

Every Gym Challenge card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 47 cards from the set pass. 47 of them (100%) have a gem-rate sample of at least ten graded copies in the population reports, and 22 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 Sabrina's Gengar from Gym Challenge, gems 6.5% of the time across 2,539 graded copies: +$297 is what a long run of submissions would average, $4,081 is what one lucky copy returns.

The median gem rate across the sampled Gym Challenge cards is 11.6%. Roughly one submitted copy in 9 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 47 ranked cards, 14 still cover raw price plus fee at PSA 9, 33 need a 10 to break even and 25 lose money on expectation. 40 rest on a hundred or more graded copies.

Before you submit a Gym Challenge 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 Gym Challenge card list, or see how gem-mint premiums run across the whole catalogue on the PSA premium index.

Gym Challenge grading questions

Which Gym Challenge card is the best to grade?

On current numbers the Sabrina's Gengar (Gym Challenge #29): 6.5% of 2,539 graded copies came back PSA 10, an expected profit of $297 per submission after the $416 grading cost, against a best case of $4,081 if it gems.

How many Gym Challenge cards are worth grading?

22 keep a positive expected value after the fee, out of the 47 with a gem-rate sample of at least ten graded copies. 47 cards on this page have a PSA 10 price that beats the raw price by more than the grading fee.

What gem rate do Gym Challenge cards get at PSA?

The median across the 47 sampled Gym Challenge cards is 11.6%, so about one in 9 of the copies collectors chose to submit came back PSA 10. The strongest rate with a sample of thirty or more is the Koga's Muk (Gym Challenge #26) at 29.6% of 115.

Does the Gym Challenge ranking apply to CGC or Beckett?

Not directly. The cost column is PSA's fee as of 2026-09-26 and the graded columns are PSA slab prices; the gem-rate sample falls back to CGC's population only when PSA has fewer than ten copies. A CGC or Beckett submission has its own fee and resale price.
