Best case only — no gem-rate evidence 2
Fewer than 10 graded copies in the PSA and CGC population reports. They clear the grading cost if they gem — that is all the numbers support.
| # | Card | Raw | PSA 9 | PSA 10 | Cost | Best case | Gem rate | Expected | Sample |
|---|---|---|---|---|---|---|---|---|---|
| 39 | $20 | — | $510 | $85 | +$405 | — | — | none <10 | |
| 40 | $31 | — | $153 | $82 | +$40 | — | — | none <10 |
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 Blastoise ranking
Every Blastoise card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 40 Blastoise printings pass. 38 of them (95%) have a gem-rate sample of at least ten graded copies in the population reports, and 28 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 Blastoise from Expedition Base Set, gems 4.9% of the time across 1,798 graded copies: +$2,670 is what a long run of submissions would average, $28,442 is what one lucky copy returns.
The median gem rate across the sampled Blastoise cards is 23.5%. Roughly one submitted copy in 4 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 38 ranked cards, 17 still cover raw price plus fee at PSA 9, 21 need a 10 to break even and 9 lose money on expectation. 38 rest on a hundred or more graded copies.
2 cards sit below the ranking with a best case only, fewer than ten graded copies. The largest best case among them is the Blastoise-GX from SM Black Star Promos at +$405.
Before you submit a Blastoise 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 Blastoise card list, or see how gem-mint premiums run across the whole catalogue on the PSA premium index.
Blastoise grading questions
Which Blastoise card is the best to grade?
On current numbers the Blastoise (Expedition Base Set #4): 4.9% of 1,798 graded copies came back PSA 10, an expected profit of $2,670 per submission after the $2,331 grading cost, against a best case of $28,442 if it gems.
How many Blastoise cards are worth grading?
28 keep a positive expected value after the fee, out of the 38 with a gem-rate sample of at least ten graded copies. The best case is broader: 40 cards on this page have a PSA 10 price that beats the raw price by more than the grading fee. The other 2 are best case only.
What gem rate do Blastoise cards get at PSA?
The median across the 38 sampled Blastoise cards is 23.5%, so about one in 4 of the copies collectors chose to submit came back PSA 10. The strongest rate with a sample of thirty or more is the Blastoise (Celebrations: Classic Collection #2) at 61.3% of 43,795.
Does the Blastoise 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.
