What's your copy worth?
Estimated. This card has enough sales to price the top 15% but not the top 5%, so pack-fresh is projected from the gap we measure between those two tiers on cards that do — about 1.4x on vintage, 1.2x on modern. $12.63. That's about +27% over a typical Near Mint copy.
ⓘ How do we work this out?
We take every real sale of this exact card over the last 12 months (24 sales), sort them by price, and read off the top 15% and top 5%. No multipliers, no guesses — the prices cleaner copies actually fetched.
Why cleaner copies cost more: buyers can see condition in the photos and pay for it. Listings sellers describe as pack fresh or gem mint land in this top band 1.7× more often than ordinary ones — the premium follows the card, not the hype.
Copies in this band are also the ones collectors send to grading: far more likely than a typical binder copy to be submitted at all — and to come back with the strong grade that carries the PSA prices shown on this page. That prospect is part of what buyers are paying for here.
These are read straight off this card's own completed sales — sort them by price and take the top 15% and top 5%. Whether your copy qualifies is a judgment made by looking at the card.

Compare graders, and the live market
The verdict above is PSA's — the grader the population report, the ROI table and the price ladder on this page all use. Trader prices all three graders against each other and adds what the asking market is doing right now.
- PSA, CGC and Beckett side by side — each on its own population and its own fees, with Beckett scored on the 9.5 its market actually pays for.
- Lightly and moderately played — the same expected return for a copy that cannot gem.
- Ask vs sold — what the live listings want, against what copies have really closed at.
- Momentum — the 30-day median against the 90-day, per grade.
- Where it sells higher — the Fanatics-versus-eBay premium, with the sale counts behind it.
- Population history — the weekly PSA census, so you can see how fast 10s are arriving before you post the card.
The odds
Professor's Research is a Secret / Rainbow in Pokémon GO — the pack's hit slot lands on Secret / Rainbow 2.5% of the time, split across 12 secret / rainbow cards in the set, so pulling this exact card is roughly 1 in 482 packs.
Estimates only. Pack odds come from CardTrack's pack model (the same one behind the pack simulator) — not an official rate. Grading odds are the real cumulative PSA population, which skews toward nicer, resubmitted copies, so it overstates the true first-submission gem rate. Full grade-by-grade breakdown below.

† Priced from PriceCharting's graded ladder — we hold no completed sale of our own at that grade. Every other row is our own sold data.
Net = graded value − raw value − grading cost (tier fee + ~$20 round-trip shipping), using PSA fees as of 2026-08-26; the paused PSA Value tier is excluded so this isn't overstated. Gem rate is estimated from cumulative PSA population, which skews toward nicer, resubmitted copies — so it overstates the true grade rate. Treat it as a guide, not a guarantee.
