Champions Festival (World Championships 2022)Grading odds
PSA has graded 20 copies. Where they landed:
PSA 10315.0%
PSA 91050.0%
PSA 8315.0%
PSA 7420.0%
Why the verdict weights the odds
A CGC/BGS 9.5 sells for $2£1.51€1.76 against $0.51£0.38€0.45 ungraded plus $79.99£60.20€70.44 at Regular. Without a PSA population report there is nothing to weight those grades by, so this is a best case rather than an average. CGC numbers cannot stand in: the prices on this ladder are PSA prices and a CGC 10 is an easier grade to reach.
1 of the 2 grades priced above had no sales at that grade, so the figure is modelled from the grades that did rather than observed.

What moves the price of this card
The Professor's Research [Professor Willow] on this page is the Holofoil printing from Sword & Shield Promo Cards, and it trades at $0.43£0.32€0.38 in near mint condition. Only one printing of this card was produced, so there is no cheaper version to confuse it with.
Graded, it runs PSA 9 $2.25£1.69€1.98, CGC/BGS 9.5 $2£1.51€1.76. PSA has graded 20 copies of it. 55 completed sales are on file.
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. 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.
