What moves the price of this card

The Dialga GX (Full Art) on this page is the Holofoil printing from SM - Ultra Prism, and it trades at $20.50 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 $286.40. 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.
