What moves the price of this card

The Tieria Erde (Store Tournament Winner Pack 03) on this page is the Holofoil printing from Gundam Promotional Cards, and it trades at $9.47 in near mint condition. The same name is on 3 other printings: Starter Deck 07: Celestial Drive ST07-010 at $3.10, Gundam Promotional Cards ST07-010 at $0.36, Starter Deck 07: Celestial Drive ST07-010 at $0.18, 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.
