Gundam Sandrock (C+).

What moves the price of this card

The Gundam Sandrock (C+) on this page is the Holofoil printing from Starter Deck 02: Wings of Advance, and it trades at $12.88 in near mint condition. The same name is on 3 other printings: Edition Beta GD01-028 at $0.80, Newtype Rising GD01-028 at $0.37, Starter Deck 02: Wings of Advance ST02-004 at $0.17, so read the set, the number and the rarity together before comparing prices.

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.
