What moves the price of this card

The Jegan on this page is the Normal printing from Freedom Ascension, and it trades at $0.17 in near mint condition. The same name is on 4 other printings: Gundam Promotional Cards GD01-016 at $20.24, Gundam Promotional Cards GD01-016 at $0.48, Edition Beta GD01-016 at $0.27, Newtype Rising GD01-016 at $0.13, 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.
