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.
PSA population 21
Every Castform card with a PSA population reading, ranked five ways. A historical PSA 10 rate is the share of graded copies that came back a 10 — how hard a 10 has been to earn, not the chance your copy earns one — and it is only quoted on cards with at least 20 graded copies; the PSA 10 tables use the same floor. PSA counts as of 15 Oct 2026. How population is measured.

How to read the Castform ranking
Every Castform card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 3 Castform printings pass. 3 of them (100%) have a gem-rate sample of at least ten graded copies in the population reports, and 2 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 Sunny Castform from Hidden Legends, gems 31.4% of the time across 35 graded copies: +$9 is what a long run of submissions would average, $33 is what one lucky copy returns.
The median gem rate across the sampled Castform cards is 31.4%. 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 3 ranked cards, 1 still covers raw price plus fee at PSA 9, 2 need a 10 to break even and 1 loses money on expectation. 1 rests on a hundred or more graded copies.
Before you submit a Castform 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 Castform card list, or see how gem-mint premiums run across the whole catalogue on the PSA premium index.
