Leo.

What moves the price of this card

The Leo on this page is the Normal printing from Freedom Ascension, and it trades at $0.15 in near mint condition. The same name is on 4 other printings: Gundam Promotional Cards T-004 at $59.99, Starter Deck 02: Wings of Advance ST02-007 at $4.51, Newtype Rising T-004 at $1.48, Starter Deck 02: Wings of Advance ST02-007 at $0.15, 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.
