What moves the price of this card

The Mystery Plate Beta on this page is the Reverse Holofoil printing from Skyridge, and it trades at $28.16 in near mint condition. The other 1 printing of the same card sits lower, which is normal: the scarcer print run always carries the premium.

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 $559.50. 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.
