Ranked two ways
Screening spread is the money figure - cash left after costs. Premium ratio shows how many times the raw price a gem copy fetches. They rank differently.
The widest premium on the board
Slowpoke
Slowpoke 204/198 from SV01: Scarlet & Violet Base Set sits at the top of this week's screening list on the strength of an exceptionally wide gap between its modest raw price and its PSA 10 value, giving it the largest estimated screening spread in the table. The illustration rare treatment places the card in a category that collectors have consistently chased in graded form, and the cobblestone street scene by Toshinao Aoki, with its warm afternoon light, unhurried composition and the tiny pink Slowpoke wandering along the pavement, gives it a distinct visual identity that stands apart from standard set artwork. The trade-off is a relatively low historical PSA 10 rate, so raw condition is everything here; a copy that misses PSA 10 will land at a PSA 9 value that sits close to its raw price, leaving very little room for error. Worth watching carefully, but only with a copy that self-grades conservatively as near-mint or better under strong light.
All eight, card by card
Each screened card in its own dossier: raw and graded prices, the premium multiple, the estimated spread, why it's here and what could go wrong.
The whole screen in one table
Every candidate, one row each - built to be screenshotted. Sorted by screening spread.
What could go wrong
Grading is a bet on condition. The risks below apply to every card here - plus the sharper downside on the cards where a PSA 9 leaves little over raw.
- Condition cannot be judged from a catalogue image.
- Most raw cards will not grade 10.
- Grading fees, timelines and premiums all move.
- PSA 10 comps reflect recent last-sold prices; future realisations may differ.

Grading, premiums & how we screen
The questions readers ask most about PSA grading and how Grading Watch is put together.
01What is PSA grading?⌄
PSA grading is a professional authentication and condition assessment service provided by Professional Sports Authenticator (PSA). Cards are examined for centering, corners, edges and surface before being assigned a grade from 1 to 10, with PSA 10 Gem Mint representing the highest standard.
02Is PSA grading worth it?⌄
Grading can be worthwhile when the graded premium outweighs the cost of grading and selling the card. Not every card benefits, and even valuable cards may not justify grading if they are unlikely to reach a high grade. Grading Watch highlights cards with strong PSA 10 premiums, but it is not a prediction that any given copy will grade a 10.
03How does Grading Watch choose cards?⌄
Each issue we screen the catalogue on price, era and rarity, then verify the shortlist against recent graded and raw comparables from live market data. We rank the survivors by screening spread and feature the eight widest. It is a screening list, not a submission recommendation.
04What is the “screening spread”?⌄
Screening spread is the PSA 10 price minus the raw price, minus estimated grading, shipping, selling and transaction costs. It is labelled as an estimate before tax and condition risk - the exact cost assumptions are printed in the methodology box and are placeholders pending confirmation.
05Does a big premium mean I will make money?⌄
No. The premium only pays out on a genuine PSA 10. Most raw cards will not grade 10, condition cannot be judged from a catalogue image, and premiums move with the market. Treat every figure as a screen, not a promise.
06How often is Grading Watch updated?⌄
Grading Watch runs fortnightly, with a fresh screen of raw cards and their graded premiums each issue.
