Champions Festival (World Championships 2022)Grading odds
CGC has graded 32 copies. Where they landed:
These are CGC grades. The prices above are for PSA slabs, and a CGC 10 is not the same grade as a PSA 10, so read the two as separate markets rather than one.
Why the verdict weights the odds
Only 22.7% 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 $2.23£1.68€1.97 on average against $101.70£76.54€89.56 for the card plus $79.99£60.20€70.44 at Regular, the cheapest level PSA will insure it at. That loses $99.47£74.86€87.60, so a copy is worth more raw.
1 of the 4 grades priced above had no sales at that grade, so the figure is modelled from the grades that did rather than observed.

The Rillaboom on this page is the Holofoil printing from Sword & Shield Promo Cards, and it trades at $0.53£0.40€0.47 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 7 $0.82£0.62€0.72, PSA 8 $2£1.51€1.76, PSA 9 $3.01£2.27€2.65, CGC/BGS 9.5 $3£2.26€2.64. PSA has graded 22 copies of it. 38 completed sales are on file.
Is Rillaboom from Sword & Shield Promo Cards worth grading?
On the numbers, no. The average submission is worth $2.23 with every grade weighted by how often this card comes back at it, against $1.71 for a raw copy plus $99.99 to send it through PSA Regular, so it loses $99.47.
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.
