What makes one Dialga-GX worth more than another?
4 versions are chase rarities (Rare Ultra and Rare Rainbow), and these are usually the most valuable. 2 versions are secret rares, numbered past the set total. No version is Standard-legal right now, so demand comes from collectors. Condition is the biggest swing — a Near Mint copy can sell for several times a played one.
