Grading odds

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

✓ Worth grading
$231.90
top slab, best case

A PSA 10 sells for $231.90 against $1.46 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 Professor's Research [Professor Oak] on this page is the Holofoil printing from Celebrations, and it trades at $0.29 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 $231.90. 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.
