Best Thundurus Cards to Grade

How to read the Thundurus ranking

Every Thundurus card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 4 Thundurus printings pass. 4 of them (100%) have a gem-rate sample of at least ten graded copies in the population reports, and 3 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 Thundurus-EX from Plasma Freeze, gems 4.4% of the time across 481 graded copies: +$1,290 is what a long run of submissions would average, $27,555 is what one lucky copy returns.

The median gem rate across the sampled Thundurus cards is 6.9%. Roughly one submitted copy in 14 came back PSA 10, and most rows here still cover raw price plus fee at PSA 9, so the PSA 9 price does most of the work. Of the 4 ranked cards, 3 still cover raw price plus fee at PSA 9, 1 needs a 10 to break even and 1 loses money on expectation. 3 rest on a hundred or more graded copies.

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