Alakazam (No Rarity Symbol)Grading odds
PSA has graded 45 copies. Where they landed:
Why the verdict weights the odds
Only 48.9% of copies reach a 10, which is why the top price is the wrong number to plan around. Weighting each grade’s PSA price by these odds, a submission is worth $31.57£23.54€28.24 on average against $107.54£80.19€96.20 for the card plus $79.99£59.65€71.55 at Regular, the cheapest level PSA will insure it at. That loses $75.97£56.65€67.96, so a copy is worth more raw.

What is a PSA 10 Professor Oak's Research worth?
A PSA 10 Professor Oak's Research from Japanese Base Expansion Pack sells for $56. 57.1% of the copies PSA has graded came back a 10, so that price is the best case rather than the one a submission should expect.
Is Professor Oak's Research from Japanese Base Expansion Pack worth grading?
On the numbers, no. The average submission is worth $34.86 with every grade weighted by how often this card comes back at it, against $7.55 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $72.68.
Condition does most of the work below the surface. A copy with soft corners or a print line off centre trades well under the market price shown here, and a copy clean enough to grade trades well above it, which is why the PSA 10 sits at $56£41.76€50.09. Before you value your own copy, look at the corners under a light and check the centring on the back, where most cards give themselves away.
