Grading odds
No population report for this card, so the prices below are the best case rather than the likely one.
The top slab against $22.40 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 Keldeo GX (Secret) on this page is the Holofoil printing from SM - Unified Minds, and it trades at $22.40 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. 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.
