Gundam Barbatos Lupus Rex (EX) (R+).

What moves the price of this card

The Gundam Barbatos Lupus Rex (EX) (R+) on this page is the Holofoil printing from Eternal Nexus, and it trades at $12.70 in near mint condition. The same name is on 3 other printings: Freedom Ascension GD05-051 at $8.25, Freedom Ascension GD05-051 at $0.38, Eternal Nexus EB01-004 at $0.25, 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.
