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 Wooper ranking
Every Wooper card listed here clears one bar: its PSA 10 price beats its raw price by more than the cost of grading it. 7 Wooper printings pass. 7 of them (100%) have a gem-rate sample of at least ten graded copies in the population reports, and 5 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 Wooper from Aquapolis, gems 20.9% of the time across 134 graded copies: +$299 is what a long run of submissions would average, $1,152 is what one lucky copy returns.
The median gem rate across the sampled Wooper cards is 23.9%. 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 7 ranked cards, 2 still cover raw price plus fee at PSA 9, 5 need a 10 to break even and 2 lose money on expectation. 4 rest on a hundred or more graded copies.
Before you submit a Wooper 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 Wooper card list, or see how gem-mint premiums run across the whole catalogue on the PSA premium index.
