Grading odds

No population report for this card, so the prices below are the best case rather than the likely one.

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.

✓ Worth grading
$139.99
top slab, best case

A PSA 10 sells for $139.99 against $1.50 raw plus a $25 fee. Without a population report we cannot weight that by the odds, so treat it as the best case: most submissions come back below the top grade.

What moves the price of this card

The Weavile (Cosmos Holo) on this page is the Holofoil printing from Mega Evolution Promo, and it trades at $0.40 in near mint condition. Only one printing of this card was produced, so there is no cheaper version to confuse it with.

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 $139.99. 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.
